Analog Devices Inc. ADA4077-2 双通道放大器
Analog Devices ADA4077-2 高精度双通道放大器提供业界最佳的失调电压、电压温度漂移、带宽、压摆率和噪声综合性能。ADI ADA4077-2 op 放大器具有高直流精度、低噪声、高速和低电源电流等特性，因此特别适用于过程控制、化学和环境监测、电机控制、电子测试和仪器仪表应用。ADA4077-2在1kHz时具有3.9MHz带宽和7-nV/√Hz电压噪声；在25ºC、 ±15-Vdc标称电源电压工作条件下，额定功耗仅为400µA。同时提供两种不同等级的失调电压和温度漂移，可灵活满足设计工程师不同预算和封装要求。
Analog Devices Inc. ADA4077 High Precision Amplifiers are useful in line powered and portable instrumentation, precision filters, and voltage or current measurement and level setting. Unlike amplifiers by some competitors, the ADA4077 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.
