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 transducers or low-level voltage signals. 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 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-resolution measurement applications in smart transmitters, industrial 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.
