INA116PA Datasheet

Instrumentation Amplifiers


The INA116PA 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 INA116PA is available in 16-pin plastic DIP and SOL-16 surface-mount packages, specified for the –40°C to +85°C temperature range. INA116PA 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 INA116PA Applications • Laboratory Instrumentation• Ph Measurement• Ion–Specific Probes• Leakage Current Measurement
