They use delta-sigma technology and provide single cycle settling time for multiplexed applications. Through a single pin, the LTC2415 can be configured for better than 110dB input differential mode rejection at 50Hz or 60Hz ±2%, or it can be driven by an external oscillator for a user defined rejection frequency. The LTC2415-1 can be configured for better than 87dB input differential mode rejection over the range of 49Hz to 61.2Hz (50Hz and 60Hz ±2% simultaneously). The inter- nal oscillator requires no external frequency setting com- ponents. 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 LTC2415/LTC2415-1. The DC common mode input rejec- tion is better than 140dB. The LTC2415/LTC2415-1 communicate through a flexible 3-wire digital interface which is compatible with SPI and MICROWIRE TM protocols. , LTC and LT are registered trademarks of Linear Technology Corporation. 24-Bit No Latency ∆ΣTM ADCs with Differential Input and Differential Reference No Latency ∆Σ is a trademark of Linear Technology Corporation.
