The ADS1218Y/250 is a precision wide dynamic range delta-sigma Analog-to-digital Converter (ADC) with 24-bit resolution and Flash memory operating from 2.7 to 5.25V supplies. The delta-sigma A/D converter provides up to 24-bit of no missing code performance and effective resolution of 22-bit. Internal buffering can be selected to provide very high input impedance for direct connection to transducers or low-level voltage signals. Burnout current sources are provided that allow for the detection of an open or shorted sensor. An 8-bit digital-to-analog (D/A) converter provides an offset correction with a range of 50% of the FSR (full-scale range). The A/D conversion is accomplished with a second-order delta-sigma modulator and programmable sinc filter. The reference input is differential and can be used for ratiometric conversion. The on-board current DACs (digital-to-analog converters) operate independently with the maximum current set by an external resistor.
