CS5016 CS5014 CS5012A
General Description
The CS5012A/14/16 are 12, 14 and 16-bit monolithic
analog to digital converters with conversion times of
7.2 s, 14.25 s and 16.25 s. Unique self-calibration cir-
cuitry 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 select-
able.
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, in-
herent 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.
