The quad ADA4077-4S 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 1000 pF with no external compensation.
Applications for this amplifier include sensor signal conditioning (such as thermocouples, resistance temperature detectors (RTDs), strain gages), process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems. The ADA4077-4S is useful in line powered and portable instrumentation, precision filters, and voltage or current measurement and level setting.
The ADA4077-4S is offered in a 14-lead flatpack package.
- Process control front-end amplifiers
- Optical network control circuits
- Precision sensors and controls
- Precision filters
- Space & Military
