GENERAL DESCRIPTION  
The single ADA4077-1, dual ADA4077-2, and quad ADA4077-4  
amplifiers feature 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.  
60  
Applications for this amplifier include sensor signal conditioning  
(such as thermocouples, resistance temperature detectors (RTDs),  
strain gages), process control front-end amplifiers, and precision  
diode power measurement in optical and wireless transmission  
systems. The ADA4077-1/ADA4077-2/ADA4077-4 are useful in  
line powered and portable instrumentation, precision filters,  
and voltage or current measurement and level setting.

Unlike other amplifiers, the ADA4077-1/ADA4077-2/  
ADA4077-4 have an MSL1 rating that is compliant with the most  
stringent of assembly processes, and they are specified over the  
extended industrial temperature range from −40°C to +125°C for  
the most demanding operating environments.
