16-Bit No Latency ∆Σ™ ADC  
FEATURES  
DESCRIPTION  
TheLTC®2439-1isa16-channel(8-differential)micropower  
16-bit∆Σanalog-to-digitalconverter.Itoperatesfrom2.7V  
to 5.5V and includes an integrated oscillator, 0.12LSB  
INL and 1µV RMS noise. It uses delta-sigma technology  
and provides single cycle settling time for multiplexed  
applications. Through a single pin, the LTC2439-1 can be  
configuredforbetterthan87dBdifferentialmoderejection  
at 50Hz and 60Hz 2ꢀ, or it can be driven by an external  
oscillator for a user-defined rejection frequency. The  
internal oscillator requires no external frequency setting  
components.
