DESCRIPTION

The ADS801 is a low power, monolithic 12-bit, 25MHz

analog-to-digital converter utilizing a small geometry

CMOS process. This COMPLETE converter includes

a 12-bit quantizer, wideband track/hold, reference, and

three-state outputs. It operates from a single +5V

power supply and can be configured to accept either

single-ended or differential input signals.

The ADS801 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, instru-

mentation and video applications.

This high performance A/D converter is specified over

temperature for AC and DC performance at a 25MHz

sampling rate. The ADS820 is available in 28-lead

SOIC and 28-lead SSOP packages.
