PCM1681
Description
The PCM1681 and PCM1681-Q1 are CMOS monolithic integrated circuits which feature an eightchannel 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.
