PCM1771RGA

ADCs/DACs - Special Purpose Overview

The PCM1771RGA is a stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 48 kHz. The device integrates a headphone amplifier and operates on a single power supply ranging from 1.6 V to 3.6 V. Key performance metrics include a signal-to-noise ratio of 98 dB and a total harmonic distortion plus noise of 0.007%. It utilizes a serial 3-wire interface for control and data input. The component is housed in a 20-pin VQFNP package and draws a typical operating current of 2.5 mA, designed for low-power applications.
