The LTC2480 includes on-chip programmable gain and  
an oscillator. The LTC2480 can be configured to provide a  
programmable gain from 1 to 256 in 8 steps, measure an  
external signal or internal temperature sensor and reject  
line frequencies. 50Hz, 60Hz or simultaneous 50Hz/60Hz  
line frequency rejection can be selected as well as a 2x  
speed-up mode.

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.
