The small footprints of the Gs809X series packages save space on printed circuit boards and enable the design of smaller electronic products Power Supply Bypassing and Board Layout GS809X series operates from a single 2.5V to 5.5V supply or dual +1.25V to +2.75V supplies For best performance, a01uF ceramic capacitor should be placed close to the VoD pin in single supply operation For dual supply operation, both VoD and vss supplies should be bypassed to ground with separate 0. 1 uF ceramic capacitors Low Supply Current The low supply current (typical 4.2mA per channel) of GS809X series will help to maximize battery life. They are ideal for battery powered systems Operating Voltage GS809X series operate under wide input supply voltage(2. 5V to 5.5V. In addition, all temperature specifications apply from -40C to +125C. Most behavior remains unchanged throughout the full operating voltage range. These guarantees ensure operation throughout the single Li-lon battery lifetime Rail-to-Rail output Rail-to-Rail output swing provides maximum possible dynamic range at the output. This is particularly important when operating in low supply voltages. The output voltage of G s809x series can typically swing to less than 30mv from supply rail in light resistive loads(lkQ), and 120mV of supply rail in moderate resistive loads(1500) Capacitive Load Tolerance The Gs809X family is optimized for bandwidth and speed, not for driving capacitive loads. Output capacitance will create a ole in the amplifier's feedback path, leading to excessive peaking and potential oscillation. If dealing with load capacitance is a requirement of the application the two strategies to consider are(1)using a small resistor in series with the amplifier's output and the load capacitance and(2)reducing the bandwidth of the amplifier's feedback loop by increasing the overall naise gain Figure 2 shows a unity gain follower using the series resistor strategy. the resistor isolates the output from the capacitance and, more importantly, creates a zero in the feedback path that compensates for the pole created by the output capacitance R OUT Figure 2. Indirectly Driving a Capacitive Load Using Isolation Resistor The bigger the Riso resistor value, the more stable VOUT will be. However, if there is a resistive load RL in parallel with the capacitive load, a voltage divider(proportional to RisoRL)is formed, this will result in a gain error www.gainsll.com AO 920 saISI Gs8091/92/9491N/92N The circuit in Figure 3 is an improvement to the one in Figure 2 R provides the DC accuracy by feed-forward the vin to R. Cr and Riso serve to counteract the loss of phase margin by feeding the high frequency component of the output signal back to the amplifier's inverting input, thereby preserving the phase margin in the overall feedback loop. Capacitive drive can be increased by increasing the value of CF. This in turn will slow down the pulse response Figure 3.
