Analog Devices Inc. ADA4522-1 超低噪声放大器

Analog Devices ADA4522-1 单通道、零漂移、运算放大器针对随时间、温度和电压条件变化的总精度进行了优化。 ADA4522-1 运算放大器提供低噪声和低功耗、接地传感输入和轨到轨输出。 ADA4522-1 在 5.0V、30V、55V 电源电压下保证具有额定性能,可在 4.5V 至 55V 范围内运行。 片上滤波实现较高的抗电磁干扰 (EMI) 能力。 该运算放大器工作电压及温度范围广,开环增益大,直流与交流误差非常小,因此很适合放大非常小的输入信号。 这些特性还使得这些器件在各种广泛应用中准确复制大信号。

The ADA4522-1, ADA4522-2, and ADA4522-4 Op Amps are fully specified over the extended industrial temperature range of -40°C to +125°C. These devices are offered in 8-lead MSOP, 8-lead SOIC, 14-lead SOIC, and 14-lead TSSOP packages for design flexibility.
