INSTRUMENTATION AMPLIFIER  
DESCRIPTION  
FEATURES  
TheINA2128isadual, lowpower, generalpurposeinstrumen-  
tation amplifier offering excellent accuracy. Its versatile  
3-op amp design and small size make it ideal for a wide range  
of applications. 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  
A single external resistor sets any gain from 1 to 10,000.  
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  
The INA2128 is available in SOL-16 packages, specified  
for the –40°C to +85°C temperature range.
