DESCRIPTION

The ADS820 is a low-power, monolithic 10-bit, 20MHz 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 ADS820 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

DC-performance at a 20MHz sampling rate. The ADS820

is available in an SO-28 package.
