froma5Vlowvoltagesupply,flexiblehighvoltagesupplies,  
andusingtheinternalreferenceandbuffer,thisSoftSpanTM  
ADC can be configured on a conversion-by-conversion  
basis to accept 1ꢀ.2ꢁV, ꢀV to 1ꢀ.2ꢁV, 5.12V, or ꢀV to  
5.12V signals on any channel. Alternately, the ADC may  
be programmed to cycle through a sequence of channels  
and ranges without further user intervention.

No Pipeline Delay, No Cycle Latency  
The wide input common mode range and 118dB CMRR of  
the LTC2335-18 analog inputs allow the ADC to directly  
digitize a variety of signals, simplifying signal chain de-  
sign. This input signal flexibility, combined with 3LSB  
INL, no missing codes at 18 bits, and 96.7dB SNR, makes  
the LTC2335-18 an ideal choice for many high voltage  
applications requiring wide dynamic range.
