Description

The ADS800 is a low-power, monolithic 12-bit, 40MHz 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 ADS800 employs digital error correction to provide excellent Nyquist differential linearity performance for de manding 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 over tem-perature for AC and DC performance at a 40MHz sampling rate. The ADS800 is available in an SO-28 package.
