Product details

Typical applications include precision analog signal conditioning, sensor interfaces (photodiode, pH, thermocouple), and active filters where low input bias current and moderate speed are required.

At 220 µA supply current, this op-amp fits into power-constrained designs running off a 5 V or 12 V rail. The 5 pA input bias current is the headline spec for high-impedance sources — a photodiode or pH electrode won't see significant offset from the amplifier's input. The 60 mA output drive per channel is enough to swing into a 2 kΩ load or drive a moderate ADC input.

Frequently asked questions
