INA2128  
Dual, Low Power  
INSTRUMENTATION AMPLIFIER  
DESCRIPTION  
FEATURES  
The INA2128 is a dual, low power, general purpose  
instrumentation amplifier offering excellent accuracy.  
Its versatile 3-op amp design and small size make it  
idealforawiderangeofapplications. Current-feedback  
input circuitry provides wide bandwidth 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: ±2.25V to ±18V  
LOW QUIESCENT CURRENT: 700µA / IA  
16-PIN PLASTIC DIP, SOL-16  
Asingleexternalresistorsetsanygainfrom1to10,000.  
Internal input protection can withstand up to ±40V  
without damage.  
The INA2128 is laser trimmed for very low offset  
voltage (50µV), drift (0.5µV/°C) and high common-  
mode rejection (120dB at G 100). It operates with  
power supplies as low as ±2.25V, and quiescent current  
is only 700µA per IA—ideal for battery operated and  
multiple-channel systems.  
APPLICATIONS  
SENSOR AMPLIFIER  
THERMOCOUPLE, RTD, BRIDGE  
MEDICAL INSTRUMENTATION

BATTERY OPERATED EQUIPMENT  
The INA2128 is available in 16-pin plastic DIP, and  
SOL-16 surface-mount packages, specified for the  
–40°C to +85°C temperature range.
