DESCRIPTION
The ADS1212 and ADS1213 are precision, wide dynamic
range, delta-sigma Analog-to-Digital (A/D) converters with
24-bit resolution operating from a single +5V supply. The
differential inputs are ideal for direct connection to trans-
ducers or low-level voltage signals. The delta-sigma archi-
tecture is used for wide dynamic range and to guarantee 22
bits of no missing code performance. An effective resolu-
tion of 20 bits is achieved through the use of a very low-
noise input amplifier at conversion rates up to 10Hz. Effec-
tive 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 providing a low-noise programmable
gain amplifier with a gain range of 1 to 16 in binary steps.
The ADS1212 and ADS1213 are designed for high-resolu-
tion measurement applications in smart transmitters, indus-
trial process control, weigh scales, chromatography and
portable instrumentation. Both converters include a flexible
synchronous serial interface which is SPI compatible and
also offers a two-wire control mode for low-cost isolation.
The ADS1212 is a single channel converter and is offered in
both DIP-18 and SO-18 packages. The ADS1213 includes a
4-channel input multiplexer and is available in DIP-24,
SO-24, and SSOP-28 packages.
