Analog Devices ADA4177 Operational Amplifiers offer a low offset voltage & drift, low input bias current, low noise, and low supply current. With capacitive loads of more than 1000pF, outputs are stable with no external compensation. Setting a new standard in precision amplifier robustness, the inputs of the ADA4177 provide input protection against signal excursions 32V beyond either supply, as well as 70dB of rejection for electromagnetic interference (EMI) at 1000MHz.
The devices operate over the −40°C to +125°C industrial temperature range and are available in 8-lead SOIC and 8-lead MSOP packages.
ADA4177 operational amplifiers are well-suited for sensor signal conditioning (such as thermocouples, RTDs, and strain gauges), process control front-end amplifiers, and precision diode power measurement in optical & wireless transmission systems.
