DESCRIPTION
The ADS801 is a low power, monolithic 12-bit, 25MHz
analog-to-digital converter utilizing a small geometry
CMOS process. This COMPLETE converter includes
a 12-bit quantizer, wideband track/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
demanding imaging applications. Its low distortion,
high SNR and high oversampling capability give it the
extra margin needed for telecommunications, instru-
mentation and video applications.
This high performance A/D converter is specified over
temperature for AC and DC performance at a 25MHz
sampling rate. The ADS820 is available in 28-lead
SOIC and 28-lead SSOP packages.
