The LTC2412CGN#PBF is a 2-channel differential input micropower 24-bit no latency sigma-delta? Analog-to-digital Converter (ADC) with an integrated oscillator. It provides 2ppm INL and 0.16ppm RMS noise over the entire supply range. The two differential channels are converted alternately with channel ID included in the conversion results. It uses delta-sigma technology and provides single conversion settling of the digital filter. Through a single pin, the ADC can be configured for better than 110dB input differential mode rejection at 50/60Hz±2% or it can be driven by an external oscillator for user defined rejection frequency. The internal oscillator requires no external frequency setting components. 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.
