Precision Low Input Bias

• IB can vary from few fA to many μA, depending on the input

device.

• Some input structures have well-matched IB.

• FET op amp’s IB doubles with every 10°C rise in temperature.

• Some structures have IB which may flow in either direction.

- Usually CMOS/JFET amplifiers.

• Intersil’s new JFET amplifier (ISL28210) employs bias cancelling

structure to offer low bias current over temperatures.

• Low IB amplifiers are ideal for photodiode, high impedance type

applications.

In an ideal amplifier, there should be no current flow into

the input terminals of an op amp. In general, there are

always two input bias currents, IB+ and IB-.
