GENERAL DESCRIPTION
The nAD1220 is a compact, high-speed, very low power 12-bit monolithic analog-to-
digital converter, implemented in a 0.35碌m CMOS process. It has 12-bit resolution
with close to 10 effective bits, and more than 10 bit dynamic range for video signals.
The converter includes sample and hold. The full-scale range can be set between
鹵0.6V
and
鹵1.7V
using external references. It operates from a single 2.8-3.6V supply
- compatible with modern digital systems. Most converters in this performance range
demand at least a +5V supply. Its low distortion and high dynamic range offers the
performance needed for demanding imaging, multimedia, telecommunications and
instrumentation applications. The conversion rate can be increased to 40MHz while
keeping SINAD higher than 50dB. An evaluation kit is available, see ordering
information below.
