CS5012A CS5014 CS5016  
16-, 14-, & 12-bit Self-calibrating A/D Converters  
Features  
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.  
z Monolithic CMOS A/D Converters  
– Microprocessor Compatible  
– Parallel & Serial Output  
– Inherent Track/Hold Input  
z True 12-bit, 14-bit, and 16-bit Precision  
z Conversion Times  
– CS5016: 16.25 µs  
– CS5014: 14.25 µs  
– CS5012A: 7.20 µs  
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).  
z Linearity Error: ±0.001% FS  
– Guaranteed No Missing Codes  
z Self-calibration Maintains Accuracy  
– Accurate Over Time & Temperature  
z Low Power Consumption  
– 150 mW
