They use delta-sigma technology and provide single cycle digital filter settling time (no latency delay) for multiplexed applications. The first conversion after the channel is changed is always valid. Through a single pin the LTC2404/ LTC2408 can be configured for better than 110d B rejection at 50Hz or 60Hz ± 2%, or 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 converters accept any external reference voltage from 0.1V to VCC. With their extended input conversion range of - 12.5% VREF to 112.5% VREF the LTC2404/LTC2408 smoothly resolve the offset and overrange problems of preceding sensors or signal conditioning circuits. The LTC2404/LTC2408 municate through a flexible 4-wire digital interface which is patible with SPI and MICROWIRETM protocols. , LTC and LT are registered trademarks of Linear Technology Corporation.
