DESCRIPTION

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

to-Digital (A/D) converter utilizing a small geometry CMOS

process. This complete converter includes a 10-bit quantizer

with internal track-and-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 provide

excellent Nyquist differential linearity performance 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 DCperformance

at a 40MHz sampling rate. The ADS821 is

available in an SO-28 package.
