Product Summary
The INA116P 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℃, and only 25fA at 85℃. 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 applications of the INA116P include laboratory instrumentation, ph measurement, ion–specific probes and leakage current measurement.
