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.
