Texas Instruments ADS1211

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. view all in datasheet
