Ultra Low Input Bias Current  
INSTRUMENTATION AMPLIFIER  
DESCRIPTION  
FEATURES  
The INA116 is a complete monolithic FET-input instru-  
mentation amplifier with extremely low input bias  
current. Difet® inputs and special guarding techniques  
yield input bias currents of 3fA at 25°C, and only 25fA  
at 85°C. Its 3-op amp topology allows gains to be set  
from 1 to 1000 by connecting a single external resistor.  
LOW INPUT BIAS CURRENT: 3fA typ  
BUFFERED GUARD DRIVE PINS  
LOW OFFSET VOLTAGE: 2mV max  
HIGH COMMON-MODE REJECTION:  
84dB (G = 10)  
LOW QUIESCENT CURRENT: 1mA  
Guard pins adjacent to both input connections can be  
used to drive circuit board and input cable guards to  
maintain extremely low input bias current.  
INPUT OVER-VOLTAGE PROTECTION: ±40V  
The INA116 is available in 16-pin plastic DIP and SOL-16  
surface-mount packages, specified for the –40°C to +85°C  
temperature range.
