PCM1681PWPRG4

ADCs/DACs - Special Purpose Overview

The PCM1681PWPRG4 is an eight-channel audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It utilizes enhanced multilevel delta-sigma modulation to achieve 24-bit resolution and supports sampling rates up to 192 kHz. The device operates on a single power supply ranging from 4.5 V to 5.5 V. Key performance metrics include a signal-to-noise ratio of 105 dB and a total harmonic distortion plus noise of 0.002%. It features I2C and SPI interface types for control and is housed in a 28-pin HTSSOP package.
