The DRV612 is a single-ended, 2-Vrms stereo line driver designed to reduce component count, board space, and cost. 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 also allows the removal of the costly output dc-blocking capacitors.
The device has fixed-gain single-ended inputs with a gain-select pin. Using a single resistor on this pin, the designer can choose from 13 internal programmable gain settings to match the line driver with the codec output level. The device also reduces the component count and board space.
Line outputs have ±8-kV HBM ESD protection, enabling a simple ESD protection circuit. The DRV612 has built-in active mute control with more that 80-dB attenuation for pop-free mute on/off control.
The DRV612 is available in a 14-pin TSSOP and 16-pin VQFN. For a footprint-compatible stereo headphone driver, see the TPA6139A2.
