Texas Instruments ADS1256

the ads1255 and ads1256 are extremely low-noise 24-bit analog-to-digital (a/d) converters. they provide complete high-resolution measurement solutions for the most demanding applications. the converter is comprised of a 4th-order delta-sigma (ds) modulator followed by a programmable digital filter. a flexible input multiplexer handles differential or single-ended signals and includes circuitry to verify the integrity of the external sensor connected to the inputs. the selectable input buffer greatly increases the input impedance and the low-noise programmable gain amplifier (pga) provides gains from 1 to 64 in binary steps. the programmable filter allows the user to optimize between resolution of up to 23 bits noise-free and data rate of up to 30k samples per second (sps). view all in datasheet
