The CS5012A/14/16 are 12-, 14-, and 16-bit monolithic analog to digital converters with conversion times of µs, µs and µs. Unique selfcalibration circuitry ensures excellent linearity and differential nonlinearity, with no missing codes. Offset and full-scale errors are kept within 1/2 LSB CS5012A/14 and 1 LSB CS5016 , eliminating the need for calibration. Unipolar and bipolar input ranges are digitally selectable.

The pin compatible CS5012A/14/16 consist of a DAC, conversion and calibration microcontroller, oscillator, comparator, microprocessor-compatible 3-state I/O, and calibration circuitry. The input track-and-hold, inherent to the devices’ sampling architecture, acquires the input signal after each conversion using a fast-slewing, on-chip buffer amplifier. This allows throughput rates up to 100 kSps CS5012A , 56 kSps CS5014 , and 50 kSps CS5016 .
