产品概述
The PCM1681 and PCM1681-Q1 are CMOS monolithic integrated circuits which feature an
eight-channel 24-bit audio digital-to-analog converter (DAC) and support circuitry in small 28-lead
TSSOP PowerPAD packages. The DACs utilize Burr-Brown's enhanced multilevel delta-sigma (ΔΣ)
architecture to achieve excellent signal-to-noise performance and a high tolerance to clock
jitter.The PCM1681 and PCM1681-Q1 accept TDM (time-division multiplexed) format in addition to
industry-standard audio data formats with 16- to 24-bit audio data width. Sampling rates up to 200
kHz are supported. The PCM1681 and PCM1681-Q1 provide a sub-set of user-programmable functions
through a parallel control port, in addition to a full set of user-programmable functions through a
serial control port, SPI, or I2C. The PCM1681 supports –40°C to +85°C
for consumer grade applications and the PCM1681-Q1 supports –40°C to +105°C for automotive audio
grade systems.
