LTC2411 - 24-Bit No Latency Delta Sigma ADC with Differential Input and Reference in MSOP

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 LTC2411/LTC2411-1. The DC common mode input rejection is better than 140dB.

The LTC2411/LTC2411-1 communicate through a flexible 3-wire digital interface that is compatible with SPI and MICROWIRE™ protocols.
