DESCRIPTION

The PCM1680 is a CMOS, monolithic integrated

circuit which features eight 24-bit audio

digital-to-analog converters (DACs) and support

circuitry in a small SSOP-28. The DACs use TI's

enhanced multilevel delta-sigma (ΔΣ) architecture to achieve excellent signal-to-noise performance and a

high tolerance to clock jitter.

The PCM1680 accepts industry-standard audio data

formats with 16-bit to 24-bit audio data. Sampling

rates up to 200 kHz are supported. The PCM1680

provides a full set of user-programmable functions

through a serial control port, using an SPI or I2C

interface.
