双通道精密仪表放大器

AD8222 是一款双通道、高性能仪表放大器，每个放大器仅需一个外部电阻器即可设置 1 至 10,000 的增益。\n\n AD8222 是首款采用小型 4 mm × 4 mm LFCSP 封装的双通道仪表放大器。它需要的板面积与典型的单通道仪表放大器相同。较小的封装使通道密度可以增加 2 倍，并且可以使每个通道的成本更低，而这一切都不会影响性能。\n\n AD8222 还可以配置为单通道差分输出仪表放大器。差分输出可实现高抗噪性，这在输出信号必须在嘈杂的环境中传输（例如使用远程传感器）时很有用。该配置还可用于驱动差分输入模数转换器 (ADC)。在 G = 1 时，对于所有 • 双通道，采用4 mm × 4 mm小型LFCSP封装\n\n• 增益通过1个电阻设置（G = 1至10000），每个放大器一个电阻\n\n• 低噪声\n\n• 8 nV/√Hz (1 kHz)\n\n• 0.25 µV p-p（0.1 Hz至10 Hz）\n\n\n\n\n• 高精度直流性能（B级）\n\n• 输入失调电压：60 µV（最大值）\n\n• 输入失调漂移：0.3 µV/°C（最大值）\n\n• 输入偏置电流：1.0 nA（最大值）\n\n• CMRR：126 dB（最小值，G = 100）\n\n\n\n\n• 出色的交流性能\n\n• 带宽：140 kHz (G = 100;
