FEATURES
PRODUCT OVERVIEW
self-contained sample-hold. It is specifi cally designed for systems applica-
tions where the sample-hold is an integral part of the conversion process. The
internal sample-hold has a 6 microseconds acquisition time for a full 10V dc
input change; the AID converter has a fast 9 microseconds conversion time.
Five input voltage ranges are programmable by external pin connection; 0 to
+5V, 0 to+10V, ±2.5V, ±5V, and ±10V. Input impedance to the sample-hold is
100 megohms. Output coding is complementary binary for unipolar operation
and complimentary offset binary for bipolar operation.
sion zener reference source. The circuit also contains a fast monolithic 12-bit
successive approximation register, a clock and a monolithic sample-hold.
