PCM1798DBG4

ADCs/DACs - Special Purpose Overview

The PCM1798DBG4 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 192 kHz. The device utilizes an advanced segment architecture to achieve high performance metrics, including a signal-to-noise ratio of 123 dB. It operates on a single power supply ranging from 4.75 V to 5.25 V and draws approximately 20 mA of operating current. The component is housed in a 28-pin SSOP package and communicates via a serial 3-wire interface.
