PCM1750
Dual CMOS 18-Bit Monolithic Audio
ANALOG-TO-DIGITAL CONVERTER
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
±
5V voltage supplies. Low maxi-
mum Total Harmonic Distortion + Noise (–88dB max)
is 100% tested. The very fast PCM1750 is capable
of 4
X
x
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.
