PCM1750U

Dual CMOS 18-Bit Monolithic Audio

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● DUAL 18-BIT LOW-POWER CMOS AUDIO

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 4X x audio bandwidth oversampling rates on both

input channels simultaneously, providing greater free-

dom to designers in selecting input anti-aliasing fil-

ters.

A/D CONVERTER

● FAST 4.5µs MIN CONVERSION TIME

INCLUDING S/H

● VERY LOW MAX THD+N: –88dB Without

External Adjust

● COMPLETE WITH INTERNAL

REFERENCE AND DUAL S/H FUNCTION

● TWO CO-PHASE SAMPLED, ±2.75V

AUDIO INPUTS

● CAPABLE OF 4X PER CHANNEL

OVERSAMPLING RATE

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.

● RUNS ON ±5V SUPPLIES AND

DISSIPATES 300mW MAX

● COMPACT 28-PIN PLASTIC DIP OR SOIC
