DRV603 具有差动输入的 2Vrm DirectPath™ 无杂声可变输入增益线路驱动器

The DRV603PW is a 3-VRMS 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 and cost are critical design parameters.

Designed using TI’s patented DirectPath™ technology, The DRV603 is capable of driving 3 Vrms into a 2.5-k load with 5-V supply voltage. The device has differential inputs and uses external gain-setting resistors to support a gain range of ±1 V/V to ±10 V/V, and line outputs that have ±8 kV IEC ESD protection. The DRV603 (occasionally referred to as the ‘603) has built-in shutdown control for pop-free on/off control
