TEXAS INSTRUMENTS DRV602PW 音频功率放大器, AB, 2通道, 870 mW, 3V 至 5.5V, TSSOP, 14 引脚
The is a 3V pop-free Stereo Line Driver designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost. The device is ideal for single supply electronics where size are critical design parameters. Designed using "s patented DirectPath™ technology, the DRV602 is capable of driving 3V into an into a 2.5kR load with 5V supply voltage. The device has differential inputs and uses external gain setting resistors that supports a gain range of ±1V/V to ±10V/V. The use of external gain resistors also allows the implementation of a 2nd order low pass filter to complement DAC"s and SOC converters. The line output of the DRV602 has ±8kV IEC ESD protection. The DRV602 has built-in shutdown control for pop-free on/off control. Using the DRV602 in audio products can reduce component count compared to traditional methods of generating a 3V output.
