Each Conversion Is Accurate, Even After an Input Step Single Supply 2.7V to 5.5V Operation Internal Oscillator—No External Components Required 110dB Min, 50Hz/60Hz Notch Filter Pin Compatible with 24-Bit LTC2410/LTC2411 The LTC®2430/LTC2431 are 2.7V to 5.5V micropower 20-bit differential ∆Σ analog-to-digital converters with an integrated oscillator, 3ppm INL and 0.56ppm RMS noise. They use delta-sigma technology and provide single cycle settling time for multiplexed applications. Through a single pin, The fullscale 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 GND to VCC.
