ADS1212U .

The ADS1212U is a precision wide dynamic range delta-sigma Analog-to-digital Converter (ADC) 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-bit of no missing code performance. An effective resolution of 20-bit is achieved through the use of a very low-noise input amplifier at conversion rates up to 10Hz. Effective resolutions of 16-bit 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.
