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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can
range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to
damage because very small parametric changes could cause the device not to meet its published specifications.
