Analog Devices Inc. ADA4177 运算放大器
亚德诺半导体 ADA4177 运算放大器有低失调电压&漂移、低输入偏压电流、低噪声、低电源电流。使用 1000 pF 以上容性负载时输出稳定，无需外部补偿。ADA4177 的输入确立了精密放大器鲁棒性的新标杆，可为偏离任一电源 32 V 的信号提供输入保护，以及为 1000 MHz 时的电磁干扰（EMI）提供 70 dB 抑制能力。该器件工作在 −40°C 至 +125°C 的工业温度范围，提供 8 引脚 SOIC 和 8 引脚 MSOP 两种封装。ADA4177 运算放大器非常适合传感器信号调理（如热电偶、电阻式温度检测器（RTD）、应变电桥）、过程控制前端放大器及光学&无线电传输系统中的精密二极管功率测量。
The devices operate over the −40°C to +125°C industrial temperature range and are available in 8-lead SOIC and 8-lead MSOP packages.
ADA4177 operational amplifiers are well-suited for sensor signal conditioning (such as thermocouples, RTDs, and strain gauges), process control front-end amplifiers, and precision diode power measurement in optical & wireless transmission systems.
