It can also be tied to a voltage other than ground OUT: Amplifier Output The voltage range extends to as long as the voltage between v+ and v-is from 2. 5v to within mv of each supply rail 5.5V. If it is not connected to ground, bypass it with a V+ or +Vs: Positive Power Supply. Typically the voltage capacitor of 0. 1uf as close to the part as possible is from 2. 5V to 5.5V. Split supplies are possible as long SHDN: High on this pin logic low to shut down the as the voltage between v+ and v-is between 2.5V and device. Range Logic high enables the device and 5.5V. A bypass capacitor of 0. 1pF as close to the part as logic low shut down the device. This pin defaults to possible should be used between power supply pins or logic high if left open. between supply pins and ground Operati。m The TPH2501, TPH2502, TPH2504 is a CMOS, rail-to-rail IO, high-speed, voltage-feedback operational amplifier designed for video, high-speed and other applications It is available as a single, dual, or quad op amp. the amplifier features a 250MHz gain bandwidth, and 180V/us slew rate, but it is unity-gain stable and can be operated as a+1V/ voltage follower. The TPH2501/TPH2502/TPH2504 is specified over a power-supply range of +2.7V to +5.5V(+1.35V to #2.75V). However, the supply voltage may range from +2. 5V to +5. 5V(+1.25V to +2.75V). Supply voltages higher than 7.5v (absolute maximum) can permanently damage the amplifier. Parameters that vary over supply voltage or temperature are shown in the typical characteristics section of this datasheet Applications Information Rail-to-Rail Inputs and outputs The TPH2501, TPH2502, TPH2504 op amps are designed to be immune to phase reversal when the input pins exceed the supply voltages, therefore providing further in-system stability and predictability. Figure 1 shows the input voltage exceeding the supply voltage without any phase reversal 3As=+2.5 V -500-250 007501000 Time (us) Figure 1. No Phase Reversal Choice of feedback resistor and gain bandwidth product For applications that require a gain of +1, no feedback resistor is required. Just short the output pin to the inverting input pin For gains greater than +1, the feedback resistor forms a pole with the parasitic capacitance at the inverting ReV,A www.3peakic.com TPH2501/TPH2502/TPH2503/TPH2504 250MHZ, Precision, Rail-to-Rail l/O, CMOS input. As this pole becomes smaller, the amplifier,'s phase margin is reduced. This causes ringing in the time domain and peaking in the frequency domain. Therefore, Rp has some maximum value that should not be exceeded for optimum performance. If a large value of r must be used, a small capacitor in the few Pico farad range in parallel with RF can help to reduce the ringing and peaking at the expense of reducing the bandwidth. As far as the output stage of the amplifier is concerned, the output stage is also a gain stage with the load RF and RG appear in parallel with RL for gains other than +1. As this combination gets smaller, the bandwidth falls off. Consequently, RF also has a minimum value that should not be exceeded for optimum performance. For gain of +1, R=0 is optimum. For the gains other than +1, optimum response is obtained with ro between 3000 to 1 kQ2 The TPH2501, TPH2502 and TPH2504 have a gain bandwidth product of 120MHz For gains 25, its bandwidth can be predicted by the following equation Gain x BW=120MHz Video performance For good video performance, an amplifier is required to maintain the same output impedance and the same frequency response as DC levels are changed at the output. This is especially difficult when driving a standard video load of 150Q because the change in output current with DC level. Special circuitry has been incorporated in the TPH2501, TPH2502 and TPH2504 to reduce the variation of the output impedance with the current output. This results in dG and dP specifications of 0. 03% and 0.3, while driving 150Q at a gain of 2. Driving high impedance loads would give a similar or better dG and dP performance Driving Capacitive Loads and cables The TPH2501, TPH2502 and TPH2504 can drive 10pF loads in parallel with 1kQ2 with less than 5dB of peaking at gain of +1. If less peaking is desired in applications, a small series resistor (usually between 50 to 50Q)can be placed in series with the output to eliminate most peaking. However, this will reduce the gain slightly. If the gain setting is greater than 1, the gain resistor RG can then be chosen to make up for any gain loss which may be created by the additional series resistor at the output. When used as a cable driver, double termination is always recommended for reflection-free performance. For those applications a back-termination series resistor at the amplifier's output will isolate the amplifier from the cable and allow extensive capacitive drive. However, other applications may have high capacitive loads without a back-termination resistor. Again, a small series resistor at the output can help to reduce peaking Output Drive Capability The TPH2501, TPH2502 and TPH2504 output stage can supply a continuous output current of +100mA and still provide approximately 2.7V of output swing on a 5V supply. For maximum reliability, it is not recommended to run a continuous DC current in excess of +100mA. Refer to the typical characteristic curve Output Voltage Swing vs Output Current. For supplying continuous output currents greater than +100mA, the TPH250x may be operated in parallel. the tPh250X will provide peak currents up to 200mA, which corresponds to the typical short-circuit current. Therefore, an on-chip thermal shutdown circuit is provided to protect the TPH250x from dangerously high junction temperatures. At 160C the protection circuit will shut down the amplifier. Normal operation will resume when the junction temperature cools to below140°C. www.3peakic.com Rev.A TPH2501/TPH2502/TPH2503/TPH2504 250MHZ, Precision, Rail-to-Rail I/o, CMOS Op-amps Single Supply video Line Driver The TPH2501, TPH2502 and TPH2504 are wideband rail-to-rail output op amplifiers with large output current, excellent dG, dP, and low distortion that allow them to drive video signals in low supply applications. Figure 2 is the single supply non-inverting video line driver configuration inverting video ling driver configuration. the signal is Ac coupled by c1 R1 and R2 are used to level shift the input and output to provide the largest output swing RF and RG set the ac gain. C2 isolates the virtual ground potential. RT and R3 are the termination resistors for the line C1, C2 and C3 are selected big enough to minimize the droop of the luminance signal 47F 470F TPH250 75n 75 220uF 工 47F500 v R 750 75Q 10K 10K 220μF Figure 2. 5V Single Supply Non-Inverting and Inverting Video Line Driver Power Supply Bypassing and Printed Circuit Board Layout As with any high frequency device, a good printed circuit board layout is necessary for optimum performance. Lead lengths should be as sort as possible. The power supply pin must be well bypassed to reduce the risk of oscillation. For normal single supply operation, where the Vs- pin is connected to the ground plane, a single 4.7uF tantalum capacitor in parallel with a 0. 1uF ceramic capacitor from Vs+ to gnd will suffice. This same capacitor combination should be placed at each supply pin to ground if split supplies are to be used. In this case, the vs- pin becomes the negative supply rail For good AC performance, parasitic capacitance should be kept to a minimum Use of wire wound resistors should be avoided because of their additional series inductance. Use of sockets should also be avoided if possible Sockets add parasitic inductance and capacitance that can result in compromised performance. Minimizing parasitic capacitance at the amplifier's inverting input pin is very important the feedback resistor should be placed very close to ReV,A www.3peakic.com
