The LTC ®2411/LTC2411-1 are 2.7V to 5.5V micropower 24-bit differential ∆Σ analog-to-digital converters with an integrated oscillator, 2ppm INL and 0.29ppm RMS noise. They use delta-sigma technology and provide single cycle settling time for multiplexed applications. Through a single pin, the LTC2411 can be configured for better than 110dB differential mode rejection at 50Hz or 60Hz ±2%, and the LTC2411-1 can provide better than 87dB input differential mode rejection over the range of 49Hz to 61.2Hz, or they can be driven by an external oscillator for a user-defined rejection frequency. The LTC2411 and LTC2411-1 are identical when driven by an external oscillator. 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 indepen- dently set anywhere within the GND to VCC range of the LTC2411/LTC2411-1. The DC common mode input rejec- tion is better than 140dB. The LTC2411/LTC2411-1 communicate through a flexible 3-wire digital interface that is compatible with SPI and MICROWIRE TM protocols.
