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.
