DRV612RGTR

The DRV612RGTR from Texas Instruments is a high-performance, single-ended stereo line driver. It is engineered to reduce component count, board space, and cost, making it ideal for single-supply electronics where size and cost are critical. This device utilizes TI's patented DirectPath technology, which integrates a charge pump to generate a negative supply rail, providing a clean, pop-free ground-biased output without the need for external DC-blocking capacitors.

The DRV612RGTR is capable of delivering 2 Vrms into a 600-Ω load. It features low noise and low total harmonic distortion plus noise (THD+N), with SNR greater than 105 dB and THD+N below 0.003% at a 10-kΩ load. The device operates from a 3-V to 3.6-V supply voltage. It includes programmable fixed-gain settings, selectable via a gain-select pin, offering 13 different gain values to match various codec output levels, thereby reducing component count. An active mute function provides more than 80 dB of attenuation. For protection, the DRV612RGTR includes short-circuit and thermal protection, as well as ±8-kV HBM ESD protection on its outputs.

Available in VQFN and TSSOP packages, the DRV612RGTR is suitable for applications requiring high-quality audio output in compact designs. Its operating temperature range is -40°C to 85°C.
