It uses delta-sigma technology and provides single cycle settling time for multiplexed applications. Through a single pin the LTC2400 can be configured for better than 110d B rejection at 50Hz or 60Hz ± 2%, or it can be driven by an external oscillator for a user defined rejection frequency in the range 1Hz to 120Hz. The internal oscillator requires no external frequency setting ponents. The converter accepts any external reference voltage from 0.1V to VCC. With its extended input conversion range of - 12.5% VREF to 112.5% VREF, the LTC2400 smoothly resolves the offset and overrange problems of preceding sensors or signal conditioning circuits. The LTC2400 municates through a flexible 3-wire digital interface which is patible with SPI and MICROWIRETM protocols. , LTC and LT are registered trademarks of Linear Technology Corporation.
