DESCRIPTION
The ADS820 is a low power, monolithic 10-bit, 20MHz
analog-to-digital converter utilizing a small geometry
CMOS process. This COMPLETE converter includes
a 10-bit quantizer with internal track/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 pro-
vide excellent Nyquist differential linearity perfor-
mance 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 28-pin SOIC and SSOP
packages.
