Delta Sigma ADC
The LTC2436-1 is a 16-bit No Latency Delta Sigma ADC that offers two fully differential input channels and a differential reference input. The ADC's low noise (800 nVRMS) allows 16-bit performance with full-scale ranges from ± 2.5 V down to ± 50 mV without a PGA. Operating from a single 2.7 V to 5.5 V supply, the LTC2436-1 consumes 200 uA of supply current. Low level input signals (± 50 mV) applied to the device operating with a 100 mV reference achieve 16-Bit resolution. An on-chip oscillator provides a simultaneous 50 Hz and 60 Hz filter.
