illustrate

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

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 the sensitivity of the system for high-precision applications and accuracy. With a supply voltage range of 1.8V to 5.5V, LMP7721 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, a very wide LMP7721 is available with a gain bandwidth of 17 megahertz (GBW) while consuming only 1.3 mA. This is accompanied by a high open-loop gain of 120 dB wide GBW for precise signal conditioning. With these specifications, LMP7721 excels in various applications such as electrochemical battery amplifiers and sensor interface circuits.

The LMP7721 is to provide an input 8-pin SOIC package for an amplifier with a special isolated power supply and output pins. With the right board layout technology, the unique LMP7721 lead will prevent the PCB from reaching the input pin for leakage current. As a result, system errors will be further reduced.
