LINEAR TECHNOLOGY - LTC2414/LTC2418 handbook
Update: 28 September, 2023
The LTC2414/LTC2418 are 8-/16-channel (4-/8-differential) micropower 24-bit ∆Σ analog-to-digital converters. They operate from 2.7V to 5.5V and include an integrated oscillator, 2ppm INL and 0.2ppm RMS noise. They use delta-sigma technology and provide single cycle settling time for multiplexed applications. Through a single pin, the LTC2414/LTC2418 can be configured for better than 110dB differential mode rejection at 50Hz or 60Hz ±2%, or they can be driven by an external oscillator for a user-defined rejection frequency. The internal oscillator requires no external frequency setting components. The LTC2414/LTC2418 accept any external differential reference voltage from 0.1V to VCC for flexible ratiometric and remote sensing measurement applications. They can be configured to take 4/8 differential channels or 8/16 single-ended channels. The full-scale bipolar 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 within GND to VCC. The DC common mode input rejection is better than 140dB. The LTC2414/LTC2418 communicate through a flexible 4-wire digital interface that is compatible with SPI and MICROWIRE TM protocols.
