Description

The PCM1750U is a low cost, dual 18-bit CMOSanalog-to-digital converter optimized for dynamic sig-nal applications. The PCM1750 features true co-phasedinputs with an internal sample/hold function for eachchannel. The PCM1750U also comes complete with aninternal reference. Total power dissipation is less than300mW max using ±5V voltage supplies. Low maxi-mum Total Harmonic Distortion + Noise (88dB max)is 100% tested. The very fast PCM1750U is capableof 4X x audio bandwidth oversampling rates on bothinput channels simultaneously, providing greater free-dom to designers in selecting input anti-aliasing fil-ters.

PCM1750U outputs serial data in a format that is com-patible with many digital filter chips and comes pack-aged in a space saving 28-pin plastic DIP or SOIC.
