The ads1210 and ads1211 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 ensure 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 that 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.
