TEXAS INSTRUMENTS INA116PAG4 仪器放大器, 1个放大器, 5 mV, 0.08 V/µs, 800 kHz, ± 4.5V 至 ± 18V, DIP
The is a complete monolithic FET-input Instrumentation Amplifier with extremely low input bias current. Difet® inputs and special guarding techniques yield input bias current 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.
