LTC2415IGN#PBF

LTC2415 is a micropower 24bit differential ∆Σ analogue to digital converter. This uses delta-sigma technology and provide 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 internal oscillator requires no external frequency setting components. The converters accept any external differential reference voltage from 0.1V to VCC for flexible ratiometric and remote sensing measurement configurations. The reference common mode voltage, VREFCM, and the input common mode voltage, VINCM, may be independently set anywhere within the GND to VCC range of the LTC2415-1. Application includes direct sensor digitizer, weight scales, direct temperature measurement, gas analysers, strain gauge transducers, instrumentation, data acquisition, industrial process control, 6-Digit DVMs.
