LMP7721MA/NOPB

The LMP7721MA/NOPB is a 3fA input bias current Precision Amplifier. The ultra-low input bias current is 3fA, with a specified limit of ±20fA at 25°C and ±900fA 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 (6.5nV/√Hz), low DC-offset voltage (±150µV maximum at 25°C) 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 1.8 to 5.5V. The LMP7721 is part of the LMP precision amplifier family. As part of Texas Instruments' PowerWise™ products, the amplifier provides the remarkably wide-gain bandwidth product (GBW) of 17MHz while consuming only 1.3mA of current.
