Description
The CS5012A/14/16 are 12-, 14-, and 16-bit mono-
lithic analog to digital converters with conversion
times of 7.2
μ
s, 14.25

s and 16.25

s. Unique self-
calibration circuitry ensures excellent linearity and
differential nonlinearity, with no missing codes. Off-
set 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 am-
plifier. This allows throughput rates up to
100 kSps(CS5012A), 56 kSps (CS5014), and
50 kSps (CS5016).
