Analog Devices Inc. ADA4077 High Precision Amplifiers
Analog Devices Inc. ADA4077 High Precision 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 1000pF with no external compensation. Applications for this amplifier include sensor signal conditioning (such as thermocouples, RTDs, strain gauges), process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems.
Analog Devices Inc. ADA4077 High Precision Amplifiers are useful in line powered and portable instrumentation, precision filters, and voltage or current measurement and level setting. Unlike amplifiers by some competitors, the ADA4077 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.
