illustrate

LMP7721 is the industry's lowest guaranteed input bias current high-precision amplifier. The ultra-low input bias current is 3 shots, with a guaranteed limit of ± 20 FA at 25 °C and ± 900 FA at 85 °C. This is an amplifier circuit with the latest patent-pending input bias current cancellation of the latest technology. This technology also maintains ultra-low input bias current through the amplifier's entire input common-mode voltage range.

Other standout features such as low voltage noise (6.5 NV/) ), low DC offset voltage (± 150μV up to 25°C) and low offset voltage temperature coefficient (-1.5μV/°C) to improve high accuracy, sensitivity and accuracy of the application system. With a supply voltage range of 1.8V to 5.5V, LMP7721 is ideal for battery-powered portable applications. LMP7721 is part of LMP's range of high-precision amplifiers.

As part of National Semiconductor's PowerWise offering, LMP7721 offers a significantly wide gain bandwidth of 17 MHz (GBW) while consuming only 1.3 milliamps. The 120 dB GBW of high open-loop gain enables precise signal conditioning. With these specifications, LMP7721 performance for a wide range of applications such as electrochemical battery amplifiers and sensor interface circuits in Excel.

LMP7721 is a special leadout that isolates the input and output pins of the power amplifier in an 8-pin SOIC package. With the right board layout techniques, unique LMP7721 leads will reach the input pins to prevent PCB leakage current. This will further reduce system errors.
