Analog Devices Inc. ADA4610-1 精密放大器

亚德诺半导体 ADA4610-1 精密 JFET 输入单通道放大器具有低输入噪声电压、低电流噪声、低失调电压、低输入偏置电流和轨到轨输出等特性。ADA4610-1 放大器的设计特别适合高阻抗传感器放大以及采用分流的精密电流测量应用。出色的直流精度、低噪声和快速建立时间特性相结合，使 ADA4610-1 能够在医疗仪器、电子测量和自动测试设备中提供优异的精度。即使容性负载相当大，ADA4610-1 也能保持快速建立性能。此外，当输入电压超过最大共模电压范围时，ADA4610-1 不会发生输出反相。ADA4610-1 在容性负载下仍提供快速压摆率和极高稳定性，因此非常适合高性能滤波器使用。低输入偏置电流、低失调和低噪声特性，使光电二极管放大器电路具有较宽的动态范围。低噪声、低失真、高输出电流和出色的速度，使 ADA4610-1 成为音频应用的绝佳选择。

The ADA4610-1 maintains fast settling performance with substantial capacitive loads. In addition, the ADA4610-1 does not suffer from output phase reversal when input voltages exceed the maximum common-mode voltage range. The fast slew rate and great stability with capacitive loads make the ADA4610-1 ideal for high-performance filters. Low input bias currents, low offset, and low noise result in a wide dynamic range for photodiode amplifier circuits. Low noise and distortion, high output current, and excellent speed make the ADA4610-1 ideally suited for audio applications.
