Applications for this amplifier include sensor signal conditioning
(such as thermocouples, RTDs, and strain gages), process control
front-end amplifiers, and precision diode power measurement
in optical and wireless transmission systems. The ADA4077-2-EP is
useful in line powered and portable instrumentation, precision
filters, and voltage or current measurement and level setting.

Unlike amplifiers by some competitors, theADA4077-2-EP has an
MSL1 rating that is compliant with the most stringent of assembly
processes, and is specified over the extended industrial temperature
range from −55°C to +125°C for the most demanding operating
environments.
