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.

... The adjustment range is ±0.5% of FSR for zero or offset and ±0.3% for gain. The trimming pots should be located as close as possible to the converter to avoid noise pickup. Calibration of the ADC-HS12B is performed with the sample-hold connected and operating dynamically. This results in adjusting out the sample-hold errors along with the A/D converter. For slow throughput applications it is recommended that a 0.01 μ ...

... CALIBRATION PROCEDURE 1. Connect the ADC-HS12B as shown in one of the connection diagrams. The sample-hold and AID converter should be timed as shown in the timing diagram. The trigger pulse should be applied at a rate of 70 kHz or less and should be 100 nanoseconds minimum width. 2. Zero and Offset Adjustments Apply a precision voltage reference source between the selected analog input and ground ...
