DESCRIPTION  
FEATURES  
The INA128 and INA129 are low power, general  
purpose instrumentation amplifiers offering excellent  
accuracy. Their versatile 3-op amp design and small  
size make them ideal for a wide range of applications.  
Current-feedback input circuitry provides wide band-  
width even at high gain (200kHz at G = 100).  
LOW OFFSET VOLTAGE: 50µV max  
LOW DRIFT: 0.5µV/°C max  
LOW INPUT BIAS CURRENT: 5nA max  
HIGH CMR: 120dB min  
INPUTS PROTECTED TO ±40V  
WIDE SUPPLY RANGE: ±2.25 to ±18V  
LOW QUIESCENT CURRENT: 700µA  
8-PIN PLASTIC DIP, SO-8  
A single external resistor sets any gain from 1 to  
10,000. INA128 provides an industry standard gain  
equation; INA129’s gain equation is compatible with  
the AD620.  
The INA128/INA129 is laser trimmed for very low  
offset voltage (50µV), drift (0.5µV/°C) and high com-  
mon-mode rejection (120dB at G 100). It operates  
with power supplies as low as ±2.25V, and quiescent  
current is only 700µA—ideal for battery operated  
systems. Internal input protection can withstand up to  
±40V without damage.  
APPLICATIONS  
BRIDGE AMPLIFIER  
THERMOCOUPLE AMPLIFIER  
RTD SENSOR AMPLIFIER  
MEDICAL INSTRUMENTATION  
DATA ACQUISITION  
The INA128/INA129 is available in 8-pin plastic  
DIP, and SO-8 surface-mount packages, specified for  
the –40°C to +85°C temperature range. The INA128  
is also available in dual configuration, the INA2128.
