GENERAL DESCRIPTION  
The AD8237 is a micropower, zero drift, rail-to-rail input and  
output instrumentation amplifier. The relative match of two  
resistors sets any gain from 1 to 1000. The AD8237 has excellent  
gain accuracy performance that can be preserved at any gain  
with two ratio-matched resistors.  
The AD8237 is available in an 8-lead MSOP package. Performance  
is specified over the full temperature range of −40°C to +125°C.

TRADITIONAL IN-AMP  
(RAIL-TO-RAIL OUT)  
The AD8237 employs the indirect current feedback architecture to  
achieve a true rail-to-rail capability. Unlike conventional in-amps,  
the AD8237 can fully amplify signals with common-mode voltage  
at or even slightly beyond its supplies. This enables applications  
with high common-mode voltages to use smaller supplies and  
save power.

The AD8237 is an excellent choice for portable systems. With a  
minimum supply voltage of 1.8 V, a 115 µA typical supply current,  
and wide input range, the AD8237 makes full use of a limited  
power budget, yet offers bandwidth and drift performance suitable  
for bench-top systems.
