DESCRIPTION
The ADS820 is a low-power, monolithic 10-bit, 20MHz Analog-
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 ADS820 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 and video applications.
This high performance converter is specified for AC and
DC-performance at a 20MHz sampling rate. The ADS820
is available in an SO-28 package.
