This allows large externalsourceimpedancesandinputsignals,withrail-to- rail input range to be directly digitized while maintaining exceptional DC accuracy. The LTC2485 includes an on-chip oscillator. The LTC2485 can be configured through an I2C interface to reject line frequencies. 50Hz, 60Hz or simultaneous 50Hz/60Hz line frequency rejection can be selected as well as a 2x speed-up mode. The LTC2485 allows a wide common mode input range (0V to VCC) independent of the reference voltage. The reference can be as low as 100mV or can be tied directly to VCC. The LTC2485 includes an on-chip trimmed oscil- lator eliminating the need for external crystals or oscil- lators. Absolute accuracy and low drift are automatically maintained through continuous, transparent, offset and full-scale calibration.
