LMP7721 3-Femtoampere Input Bias Current Precision Amplifier

The LMP7721 is the industry’s lowest specified input bias current precision amplifier. The ultra-low input bias current is 3 fA, with a specified limit of ±20 fA at 25°C and ±900 fA at 85°C. This is achieved with the latest patent-pending technology of input bias current cancellation amplifier circu.
