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-kΩ 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. The DRV603 has an external and internal undervoltage detector that mutes the output. Using the DRV603 in audio products can reduce component count considerab...
