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 (%#x394;) 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.
