The LT1881AIS8#PBF is a precision dual R-to-R output Picoamp OA manufactured by Analog Devices. It is a high performance amplifiers designed to provide improved AC and DC accuracy, speed, and temperature stability. The LT1881AIS8#PBF has two channels of R-to-R output to provide gains up to 1V/V and output current ranges from ±10nA to ±1µA, ideal for precision current measurement and low power instrumentation applications. This device features a very low offset voltage of 5µV across -40°C to +125°C, excellent common-mode rejection ratio (CMRR) of 75dB at DC, and programmable gain. Other features of this device include low input bias current (Ib), common-mode rejection up to 140dB, unity gain output compliance, rail-to-rail common-mode output range, and low power operation. The LT1881AIS8#PBF is offered in a SOIC-8, and is suitable for use in automotive, industrial, and medical applications.
