The LTC2415/LTC2415-1 are micropower 24-bit differential ∆Σ analog to digital converters with integrated oscillator, 2ppm INL, 0.23ppm RMS noise and a 2.7V to 5.5V supply range. They use 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 LTC2415-1 can be configured for better than 87dB input differential mode rejection over the range of 49Hz to 61.2Hz (50Hz and 60Hz ±2% simultaneously). 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 full-scale differential input range is from –0.5VREF to 0.5VREF. 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/LTC2415-1. The DC common mode input rejection is better than 140dB.

The LTC2415/LTC2415-1 communicate through a flexible 3-wire digital interface which is compatible with SPI and MICROWIRE protocols.
