Texas Instruments  DRV604PWPEVM

The DRV604PWPEVM customer evaluation module demonstrates the DRV604PWP integrated circuit (IC)from Texas Instruments (TI).

The DRV604PWP is a 2Vrms Pop-Free stereo line driver with a stereo headphone driver designed toallow 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 DRV604 is capable of driving 2 Vrms into a 5kΩ load and a clean 40mW into a 32Ω headphone with a single 3.3V supply voltage. The device has differential inputs and uses external gain setting resistors, that supports a gain range of ±1V/V to ±10V/V, and line and headphone outputs have ±8kV IEC ESD protection. The DRV604 (occasionally referred to as the '604) has built-in shutdown control for pop-free on/off control.
