DESCRIPTION
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.
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.
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.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
