ADC12451 Dynamically-Tested Self-Calibrating 12-Bit Plus Sign A D Converter with Sample-and-Hold
General Description
The ADC12451 is a
CMOS 12-bit plus sign successive approximation analog-to-digital converter whose dynamic specifications (S N THD etc ) are tested and guaranteed On request the ADC12451 goes through a self-calibration cycle that adjusts linearity zero and full-scale errors The ADC12451 also has the ability to go through an Auto-Zero cycle that corrects the zero error during every conversion The analog input to the ADC12451 is tracked and held by the internal circui...
