ANALOG DEVICES LTC2415CGN#PBF Analogue to Digital Converter, 24 bit, 15 SPS, Differential, SPI, Single, 2.7 V

LTC2415CGN#PBF is a micropower 24bit differential ?? analogue to digital converter with an integrated oscillator. It uses delta-sigma technology and provides single cycle settling time for multiplexed applications. Through a single pin, the LTC2415 can be configured for better than 110dB input differential mode rejection at 50Hz or 60Hz ±2%, or it can be driven by an external oscillator for a user-defined rejection frequency. The converter accepts any external differential reference voltage from 0.1V to VCC for flexible ratiometric and remote sensing measurement configurations. The full-scale differential input range is from -0.5VREF to 0.5VREF. Applications include direct sensor digitizers, weight scales, direct temperature measurement, gas analysers, strain gauge transducers, instrumentation, data acquisition, industrial process control, and 6-digit DVMs.
