Description
The CS5012A/14/16 are 12, 14 and 16-bit monolithic an-
alog to digital converters with conversion times of 7.2 s,
14.25 s and 16.25 s. Unique self-calibration circuitry
insures 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 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 kHz (CS5012A), 56 kHz (CS5014) and 50 kHz
(CS5016).
An evaluation board (CDB5012/14/16) is available which
allows fast evaluation of ADC performance.
