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 rang...
