FEATURES  
DESCRIPTIO  
TheLTC®1594/LTC1598aremicropower,12-bitsampling  
A/Dconvertersthatfeature4-and8-channelmultiplexers,  
respectively. They typically draw only 320μA of supply  
currentwhenconvertingandautomaticallypowerdownto  
a typical supply current of 1nA between conversions. The  
LTC1594 is available in a 16-pin SO package and the  
LTC1598 is packaged in a 24-pin SSOP. Both operate on  
a 5V supply. The 12-bit, switched-capacitor, successive  
approximation ADCs include a sample-and-hold.

On-chip serial ports allow efficient data transfer to a wide  
rangeofmicroprocessorsandmicrocontrollersoverthree  
or four wires. This, coupled with micropower consump-  
tion, makes remote location possible and facilitates trans-  
mitting data through isolation barriers.

APPLICATIO S  
The circuit can be used in ratiometric applications or with  
an external reference. The high impedance analog inputs  
and the ability to operate with reduced spans (to 1.5V full  
scale) allow direct connection to sensors and transducers  
in many applications, eliminating the need for gain stages.
