PCM1770RGA TI Audio DAC | 20-VQFN (4.2x4.2) | 96kHz, 24-Bit, Low Power

Product Overview

The PCM1770RGA is a low-power, stereo audio digital-to-analog converter (DAC) from Texas Instruments. It features a 24-bit resolution, sampling rates up to 96 kHz, and an integrated headphone amplifier. The device is housed in a compact 20-pin VQFN package (4.2 mm x 4.2 mm), making it ideal for portable and space-constrained applications. It operates from a single 2.4V to 3.6V supply and consumes only 18 mW during playback, with a power-down mode reducing consumption to 1 µW.
