DESCRIPTION

The PCM1750 is a low cost, dual 18-bit CMOS

analog-to-digital converter optimized for dynamic sig-

nal applications. The PCM1750 features true co-phased

inputs with an internal sample/hold function for each

channel. The PCM1750 also comes complete with an

internal reference. Total power dissipation is less than

300mW max using

鹵5V

voltage supplies. Low maxi-

mum Total Harmonic Distortion + Noise (鈥?8dB max)

is 100% tested. The very fast PCM1750 is capable

of 4X

audio bandwidth oversampling rates on both

input channels simultaneously, providing greater free-

dom to designers in selecting input anti-aliasing fil-

ters.

PCM1750 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.
