22-Bit ANALOG-TO-DIGITAL CONVERTER  
DESCRIPTION  
FEATURES  
● DELTA-SIGMA A/D CONVERTER  
● 22 BITS NO MISSING CODES  
The ADS1212 and ADS1213 are precision, wide  
dynamic range, delta-sigma analog-to-digital converters  
with 24-bit resolution operating from a single +5V  
supply. The differential inputs are ideal for direct  
connection to transducers or low level voltage sig-  
nals. The delta-sigma architecture is used for wide  
dynamic range and to guarantee 22 bits of no missing  
code performance. An effective resolution of 20 bits  
is achieved through the use of a very low-noise input  
amplifier at conversion rates up to 10Hz. Effective  
resolutions of 16 bits can be maintained up to a  
sample rate of 1kHz through the use of the unique  
Turbo modulator mode of operation. The dynamic  
range of the converters is further increased by provid-  
ing a low-noise programmable gain amplifier with a  
gain range of 1 to 16 in binary steps.  
● 20 BITS EFFECTIVE RESOLUTION AT 10Hz  
AND 16 BITS AT 1000Hz  
● LOW POWER: 1.4mW  
● DIFFERENTIAL INPUTS  
● PROGRAMMABLE GAIN AMPLIFIER  
● SPI COMPATIBLE SSI INTERFACE  
● PROGRAMMABLE CUT-OFF FREQUENCY  
UP TO 6.25kHz  
● INTERNAL/EXTERNAL REFERENCE  
● ON CHIP SELF-CALIBRATION  
● ADS1213 INCLUDES 4 CHANNEL MUX  
The ADS1212 and ADS1213 are designed for high  
resolution measurement applications in smart trans-  
mitters, industrial process control, weigh scales, chro-  
matography and portable instrumentation. Both con-  
verters include a flexible synchronous serial interface  
which is SPI compatible and also offers a two-wire  
control mode for low cost isolation.  
APPLICATIONS  
● INDUSTRIAL PROCESS CONTROL  
● INSTRUMENTATION  
● BLOOD ANALYSIS  
The ADS1212 is a single channel converter and is  
offered in both 18-pin DIP and 18-lead SOIC pack-  
ages. The ADS1213 includes a 4 channel input multi-  
plexer and is available in 24-pin DIP, 24-lead SOIC,  
and 28-lead SSOP packages.
