ADC12441 Dynamically-Tested Self-Calibrating 12-Bit

Plus Sign A D Converter with Sample-and-Hold

General Description

The ADC12441 is a CMOS 12-bit plus sign successive ap-

proximation analog-to-digital converter whose dynamic

specifications (S N THD etc ) are tested and guaranteed

On request the ADC12441 goes through a self-calibration

cycle that adjusts positive linearity and full-scale errors to

less than

an Auto-Zero cycle that corrects the zero error during every

conversion

The analog input to the ADC12441 is tracked and held by

the internal circuitry and therefore does not require an ex-

ternal sample-and-hold A unipolar analog input voltage

range (0V to

accommodated with

The 13-bit word on the outputs of the ADC12441 gives a 2’s

complement representation of negative numbers The digi-

tal inputs and outputs are compatible with TTL or CMOS

logic levels
