The ADS1210 and ADS1211 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 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 23 bits is achieved through the use of a very low-noise input amplifier at conversion rates up to 10Hz. Effective resolutions of 20 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 ADS1210 and ADS1211 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 ADS1210 is a single channel converter and is offered in both 18-pin DIP and 18-lead SOIC packages. The ADS1211 includes a 4-channel input multiplexer and is available in 24-pin DIP, 24-lead SOIC, and 28-lead SSOP packages.
