ADA4077-2BRZ

Dual ADA4077-2 high precision amplifier 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, resistance temperature detectors (RTDs), strain gauges), process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems. The ADA4077-2 is useful in line powered and portable instrumentation, precision filters, and voltage or current measurement and level setting. It is specified over the extended industrial temperature range from -40°C to +125°C for the most demanding operating environments. Applications include process control front-end amplifiers, optical network control circuits, instrumentation, precision sensors and controls, precision filters.
