LMP7721 3 Femtoampere Input Bias Current Precision Amplifier
General Description
The LMP7721 is the industry's lowest guaranteed input bias current precision amplifier.

The ultra low input bias current is 3 fA, with a guaranteed 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 circuitry. This technology also maintains the ultra low input bias current over the entire input common mode voltage range of the amplifier. Other outstanding features, such as low voltage noise (6.5 ), low DC offset voltage (±150 µV maximum at 25°C) nV/ and low offset voltage temperature coefficient (-1.5 µV/°C), improve system sensitivity and accuracy in high precision applications. With a supply voltage range of 1.8V to 5.5V, the LMP7721 is the ideal choice for battery operated portable applications. The LMP7721 is part of the LMP® p
