The CS5012A/14/16 are 12, 14, and 16-bit monolithic A/D converters with conversion times of 7.2 µs, 14.25 µs, and 16.25 µs. Unique self-calibration circuitry ensures excellent linearity and differential non-linearity, 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 D/A converter, conversion and calibration micro-controller, oscillator, comparator, micro-processor compatible 3-state I/O, and calibration circuitry. The input track-and-hold, inherent to the sampling architecture, acquires the input signal after each conversion using a fast slewing on-chip buffer amplifier. This allows throughput rates up to 100 kHz (CS5012A), 56 kHz (CS5014), and 50 kHz (CS5016). An evaluation board (CDB5012/14/16) is available which allows fast evaluation of A/D converter performance.
