General Description

The ADC12441 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 ADC12441 goes through a self-calibration cycle that adjusts positive linearity and full-scale errors to less than ±½ LSB each and zero error to less than ±1 LSB. The ADC12441 also has the ability to go through 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 external sample-and-hold. A unipolar analog input voltage range (0V to +5V) or a bipolar range (-5V to +5V) can be accommodated with ±5V supplies.

The 13-bit word on the outputs of the ADC12441 gives a 2's complement representation of negative numbers. The digital inputs and outputs are compatible with TTL or CMOS logic levels.
