DESCRIPTION
The ADS801 is a low-power, monolithic 12-bit, 25MHz 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 single-ended or differential input
signals.
The ADS801 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, instrumentation, and video
applications.
This high-performance A/D converter is specified over tem-
perature for AC and DC performance at a 25MHz sampling
rate. The ADS820 is available in an SO-28 package.
