CS5012A CS5014 CS5016
16-, 14-, & 12-bit Self-calibrating A/D Converters
Features
Monolithic CMOS A/D Converters
– Microprocessor Compatible
– Parallel & Serial Output
– Inherent Track/Hold Input
Description
The CS5012A/14/16 are 12-, 14-, and 16-bit mono-
lithic analog to digital converters with conversion
times of 7.2
µs,
14.25
µs
and 16.25
µs.
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).

Notes: 4. Applies only in track mode. When converting or calibrating, input capacitance will not exceed 15 pF.
5. Measured from falling transition on HOLD to falling transition on EOC.
6. Conversion, acquisition, and throughput times depend on CLKIN, sampling, and calibration conditions.
The numbers shown assume sampling and conversion is synchronized with the CS5012A/14/16 ’s
conversion clock, interleave calibrate is disabled, and operation is from the full-rated, external clock.
Refer to the section
Conversion Time/Throughput
for a detailed discussion of conversion timing.
7. All outputs unloaded. All inputs CMOS levels.
8. With 300 mV p-p, 1 kHz ripple applied to each analog supply separately in bipolar mode. Rejection
improves by 6 dB in the unipolar mode to 90 dB. Figure 13 shows a plot of typical power supply
rejection versus frequency.
