The LTC®1096/LTC1096L/LTC1098/LTC1098L are  
micropower, 8-bit A/D converters that draw only 80µA of  
supplycurrentwhenconverting.Theyautomaticallypower  
down to 1nA typical supply current whenever they are not  
performing conversions. They are packaged in 8-pin SO  
packages and have both 3V (L) and 5V versions. These  
8-bit,switched-capacitor,successiveapproximationADCs  
include sample-and-hold. The LTC1096/LTC1096L have a  
single differential analog input. The LTC1098/LTC1098L  
offer a software selectable 2-channel MUX.

Direct 3-Wire Interface to Most MPU Serial Ports and  
All MPU Parallel I/O Ports  
On-chip serial ports allow efficient data transfer to a wide  
rangeofmicroprocessorsandmicrocontrollersoverthree  
wires.This,coupledwithmicropowerconsumption,makes  
remote location possible and facilitates transmitting data  
through isolation barriers.

These circuits can be used in ratiometric applications or  
with an external reference. The high impedance analog  
inputs and the ability to operate with reduced spans  
(below 1V full scale) allow direct connection to sensors  
and transducers in many applications, eliminating the  
need for gain stages.
