GENERAL DESCRIPTION  
Additional application and technical information can be found in the  
The dual ADA4077-2-EP amplifier features extremely low offset  
voltage and drift, and low input bias current, noise, and power  
consumption. Outputs are stable with capacitive loads of more  
than 1000 pF with no external compensation.

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.
