    Back to TopDescription
    The INA116 is a complete monolithic FET-input instrumentation 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.
