Analog Devices Inc. ADA4638-1 30V 精密放大器
Analog Devices ADA4638-1 30V 是一款具有轨到轨输出摆幅的自稳零精密放大器，保证可采用4.5 V至30 V单电源或者 ±2.25V至±15V 双电源供电。采用 ±5V电源时，其功耗不到0.95mA。ADI ADA4638-1的失调电压为4μV，失调漂移不到0.05 μV/℃，无1/f噪声，输入电压噪声仅为1.2μV p-p (0.1Hz至10Hz)，适合于不容许存在大误差源的高精度应用。这款器件在宽工作温度范围内的漂移接近零，对压力传感器、医疗设备以及应变计放大器应用极为有利。许多应用都可以利用ADA4638-1提供的轨到轨输出摆幅来使信噪比(SNR)达到最大。ADA4638-1的额定温度范围为−40℃至+125℃扩展工业温度范围。
Pressure sensors, medical equipment, and strain gage amplifiers benefit greatly from nearly zero drift over the wide operating temperature range. Many applications can take advantage of the rail-to-rail output swing provided by the ADA4638-1 to maximize the signal-to-noise ratio (SNR). ADA4638-1 is specified for the extended industrial (−40°C to +125°C) temperature range.
