DESCRIPTION

The ADS821 is a low power, monolithic 10-bit, 40MHz

analog-to-digital converter utilizing a small geometry

CMOS process. This COMPLETE converter includes

a 10-bit quantizer with internal track/hold, reference,

and a power down feature. It operates from a single

+5V power supply and can be configured to accept

either differential or single-ended input signals.

The ADS821 employs digital error correction to pro-

vide excellent Nyquist differential linearity perfor-

mance for demanding imaging applications. Its low

distortion, high SNR and high oversampling capability

give it the extra margin needed for telecommunications

and video applications.

This high performance converter is specified for AC

and DC performance at a 40MHz sampling rate. The

ADS821 is available in 28-pin SOIC and SSOP

packages.
