It is ideal for single-supply electronics where size and cost are critical design parameters. The DRV612 does not require a power supply greater than 3.3 V to generate its 5.6-VPP output, nor does it require a split-rail power supply. The DRV612 device is designed using TI’s patented DirectPath technology, which integrates a charge pump to generate a negative supply rail that provides a clean, pop-free ground-biased output. The DRV612 is capable of driving 2 Vms into a 600-Ω load. DirectPath technology al...
