DescripTion  
FeaTures  
The LTC®2435/LTC2435-1 are 2.7V to 5.5V micropower  
20-bit differential ∆∑ analog to digital converters with  
integrated oscillator, 3ppm INL and 0.8ppm RMS noise.  
They use delta-sigma technology and provide single  
cycle settling time for multiplexed applications. Through  
a single pin, the LTC2435 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 LTC2435-1  
can be configured for better than 87dB input differential  
mode rejection over the range of 49Hz to 61.2Hz (50Hz  
and 60Hz 2% simultaneously). The internal oscillator  
requires no external frequency setting components.
