精密放大器 Next Generation OPxx77 Wide BW Amp
Product Details
The single ADA4077-1, dual ADA4077-2, and quad ADA4077-4 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, resistance temperature detectors RTDs, strain gages, process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems. The ADA4077-1/ADA4077-2/ADA4077-4 are useful in line powered and portable instrumentation, precision filters, and voltage or current measurement and level setting.
Unlike other amplifiers, the ADA4077-1/ADA4077-2/ADA4077-4 have an MSL1 rating that is compliant with the most stringent of assembly processes, and they are specified over the extended industrial temperature range from −40°C to +125°C for the most demanding operating environments.
The ADA4077-1 and ADA4077-2 are available in an 8-lead SOIC package, including the B grade, and in an 8-lead MSOP A grade only. The ADA4077-4 is offered in a 14-lead TSSOP and a 14-lead SOIC package.
