FEATURES

●NO MISSING CODES

●LOW POWER: 250mW

●INTERNAL REFERENCE

●WIDEBAND TRACK-AND-HOLD: 65MHz

●SINGLE +5V SUPPLY

DESCRIPTION

The ADS802 is a low-power, monolithic 12-bit, 10MHz Ana-

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

process. This complete converter includes a 12-bit quantizer,

wideband track-and-hold, reference, and three-state outputs.

It operates from a single +5V power supply and can be

configured to accept either differential or single-ended input

signals.

The ADS802 employs digital error correction in order 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, test instrumentation,

and video applications.

This high-performance A/D converter is specified for AC and

DC performance at a 10MHz sampling rate. The ADS802 is

available in an SO-28 package.
