DESCRIPTION
The ADS821 is a low-power, monolithic 10-bit, 40MHz Ana-
log-to-Digital (A/D) converter utilizing a small geometry CMOS
process. This complete converter includes a 10-bit quantizer
with internal track-and-hold, reference, and a power-down
feature. It operates from a single +5V power supply and can
be configured to accept either differential or single-ended
input signals.
The ADS821 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 and video applications.
This high-performance converter is specified for AC and DC-
performance at a 40MHz sampling rate. The ADS821 is
available in an SO-28 package.
