Typical Application Circuit Using ADA4077-1ARZ Dual Supply High Precision Amplifier for Low Power Linearized RTD Circuit. The single ADA4077-1 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. 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
