ADC12441 Dynamically-Tested Self-Calibrating 12-Bit Plus Sign A D Converter with Sample-and-Hold November 1994 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 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 g LSB each and zero error to less than g 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 a 5V) or a bipolar range (b5V to a 5V) can be accommodated with g 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 Applications Y Y Y Y Y Digital signal processing Telecommunications Audio High resolution process control Instrumentation Key Specifications Y Y Y Y Y Y Y Y Y Y Resolution Conversion Time Bipolar Signal Noise Total Harmonic Distortion Aperture Time Aperture Jitter Zero Error Positive Full Scale Error g 5V Power Consumption Sampling rate 12 bits plus sign 13 8 ms...
