AD8366, DC～500 MHz，双通道数字增益微调放大器

Fri, 01 Jan 2010 05:00:00 GMT

AD8366具有出色的无杂散动态范围，适合驱动12-bit ADC。在10 MHz工作时，最大增益下的噪声系数（NF）为10.5 dB，增益每降低4 dB，NF就增加2 dB。在整个增益范围内，在10MHz下驱动500Ω负载时，对于2V p-p的输出，HD3和HD2都大于88 dBc。驱动200Ω负载时，-90 dBc的双音互调失真对应为43 dBm的OIP3。AD8366的差分输入阻抗为200Ω，以提供良好的阻抗匹配。差分输出采用电压模式，阻抗较低，为30Ω。

在整个电压范围，输出共模电压默认值为Vps/2，用户可通过VCMA与VCMB引脚进行编程调节。如果采用直流耦合工作方式，可以禁用内置的直流失调补偿环路。高通角通过OFSA与OFSB引脚上的外部电容设定。输入共模电压默认值也为Vps/2，但可以在1.2V到3.4V之间驱
