The PCM1774RGPR is a 16-bit stereo audio digital-to-analog converter from Texas Instruments, sampling at up to 50k samples per second per channel.
The exposed pad also provides a low-impedance ground return for the analog section. The 50k sample rate ceiling covers CD-quality audio (44.1 kHz) with margin.
The PCM1774RGPR accepts audio data over DSP or I²S serial interfaces, the two most common protocols for connecting to audio codecs, DSPs, or MCUs with I²S peripherals.
