INA116U Datasheet PDF - Burr Brown

●DESCRIPTION

●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.

●FEATURES

●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

●INPUT OVER-VOLTAGE PROTECTION: ±40V

●APPLICATIONS

●LABORATORY INSTRUMENTATION

●pH MEASUREMENT

●ION–SPECIFIC PROBES

●LEAKAGE CURRENT MEASUREMENT
