详细说明：信号功率放大芯片PDF FEATURES 】 PurePath™ HD Enabled Integrated Feedback Provides: – Signal Bandwidth up to 80kHz for High Frequency Content From HD Sources – Ultralow 0.03% THD at 1W into 4Ω – Flat THD at all Frequencies for Natural Sound – 80dB PSRR (BTL, No Input Signal) – >100dB (A weighted) SNR – Click and Pop Free Startup Multiple Configurations Possible on the Same PurePath™ HD technology enables traditional PCB With Stuffing Options: AB-Amplifier performance (<0.03% THD) levels while – Mono Parallel Bridge Tied Load (PBTL) providing the power efficiency of traditional class D – Stereo Bridge Tied Load (BTL) amplifiers. – 2.1 Single Ended Stereo Pair and Bridge Unlike traditional Class D amplifiers, the distortion Tied Load Subwoofer curve only increases once the output levels move into clipping. PurePath Premier Pro™Power PAD™ – Quad Single Ended Outputs • Total Output Power at 10%THD+N PurePath™ HD technology enables lower idle losses making the device even more efficient.
