CS5016 CS5014 CS5012A

16, 14 & 12-Bit, Self-Calibrating A/D Converters

Semiconductor Corporation

Features

General Description

The CS5012A/14/16 are 12, 14 and 16-bit monolithic

analog to digital converters with conversion times of

7.2µs, 14.25µs and 16.25µs. 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.

Monolithic CMOS A/D Converters

Microprocessor Compatible

Parallel and Serial Output

Inherent Track/Hold Input

•

True 12, 14 and 16-Bit Precision

•

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).

Conversion Times:

CS5016 16.25 µs

CS5014 14.25 µs

CS5012A 7.20 µs

Self Calibration Maintains Accuracy

Over Time and Temperature

•

An evaluation board (CDB5012/14/16) is available

which allows fast evaluation of ADC performance.

Low Power Dissipation: 150 mW

Low Distortion
