FEATURES  
DESCRIPTION  
TheLTC®2353-16isa16-bit, lownoise2-channelsimulta-  
neous sampling successive approximation register (SAR)  
ADC with buffered differential, wide common mode range  
picoamp inputs. Operating from a 5V low voltage sup-  
ply, flexible high voltage supplies, and using the internal  
reference and buffer, both channels of this SoftSpanTM  
ADC can be independently configured on a conversion-  
by-conversion basis to accept 1ꢀ.2ꢁV, ꢀV to 1ꢀ.2ꢁV,  
5.12V, or ꢀV to 5.12V signals. One channel may also  
be disabled to increase throughput on the other channel.

The integrated picoamp-input analog buffers, wide input  
commonmoderangeand12ꢁdB CMRRoftheLTC2353-16  
allow the ADC to directly digitize a variety of signals us-  
ing minimal board space and power. This input signal  
flexibility, combined with 1LSB INL, no missing codes  
at 16 bits, and 9ꢁ.2dB SNR, makes the LTC2353-16 an  
ideal choice for many high voltage applications requiring  
wide dynamic range.
