 peculiarity Unless otherwise noted, typical values are at T A = 25 ° C, V S = 5 V.   Input Bias Current (V CM = 1V) Maximum @ 25°C ± 20 FA Up to 85 ° C ± 900 FA Offset voltage ± 26μV Offset voltage drift -1.5μV/ ° C DC open-loop gain 120 dB DC CMRR 100 dB Input Voltage Noise (F = 1 kHz) 6.5 NV / √ Hz Total harmonic distortion 0.0007％ Supply current 1.3 mA GBW 17 MHz Slew rate (falling edge) 12.76 V/μs Supply voltage 1.8V to 5.5V Operating temperature range -40°C to 125°C 8-pin SOIC illustrate LMP7721 is the industry's lowest guaranteed input bias current high-precision amplifier. The ultra-low input bias current is 3 shots, guaranteed to limit ± 20 FA 25 °C and ± 900 FA 85 °C. This is the latest patent-pending implementation of input bias current cancellation amplifier circuit technology. This technology also maintains an ultra-low input bias current over the entire input common-mode voltage range amplifier. Other outstanding features such as low voltage noise (6.5 NV/), low DC offset voltage (± 150 μV max 25°C), and low offset voltage temperature coefficient (-1.5 μV/°C) improve the sensitivity, accuracy, applicability, and accuracy of the 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 (GBW) of 17 MHz while consuming only 1.3 milliamps. The GBW of 120 dB of high open-loop gain enables accurate 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 pin-isolated power amplifier with input and output pins available in an 8-pin SOIC package. With the right board layout technology, the unique LMP7721 leads prevent leakage currents reaching the input pin PCB. Therefore, system errors will be further reduced.   apply Photodiode amplifiers High impedance sensor amplifiers Ion chamber amplifier Electrometer amplifier pH electrode amplifier Impede amplifier
