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 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 synchronization.
This document provides technical specifications and application information for the Burr-Brown ADS1212 and ADS1213, which are precision, wide dynamic range, delta-sigma analog-to-digital converters. The ADS1212 is a single-channel converter, while the ADS1213 includes a 4-channel input multiplexer. Both devices operate from a single +5V supply and feature differential inputs ideal for direct connection to transducers.
