ADA4077-2TRMZ-EP

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 1000pF with no external compensation. Applications for this amplifier include sensor signal conditioning (such as thermocouples, RTDs, and strain gauges), 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. It is specified over the extended industrial temperature range from −55°C to +125°C for the most demanding operating environments. Applications include process control front-end amplifiers, wireless base station control circuits, optical network control circuits, instrumentation sensors and controls: thermocouples, RTDs, strain gauges, and shunt current measurements, precision filters.
