The LTC®2400 is a 2.7V to 5.5V micropower 24-bit converter with an integrated oscillator, 4ppm INL and 0.3ppm RMS noise. It uses delta-sigma technology and it provides single cycle settling time for multiplexed applications. Through a single pin the LTC2400 can be configured for better than 110dB 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 components.
The converter accepts any external reference voltage from 0.1V to 0.9 x 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 communicates through a flexible 3-wire digital interface which is compatible with SPI and MICROWIRE™ protocols.
