  • AD8366- DC~500 MHz,双通道数字增益微调放大器

    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 MoreRead more

  • ADA4960-1- Low Distortion Ultrahigh Speed Differential ADC Driver

    The ADA4960-1 is a high performance differential amplifier optimized for RF and IF applications. It achieves better than 63dB SFDR performance at frequencies up to 500 MHz, and 52dB up to 1GHz, making it an ideal driver for high speed 8-bit to 10-bit giga-sample analog-to-digital converters (ADCs).

    Unlike other wideband differential amplifiers, the ADA4960-1 has buffered inputs that MoreRead more

  • Sort: Click on the arrows beneath the parameter on which you would like to sort, ascending and descending order.

  • Add/Remove Parameters: Click on the Add/Remove Parameters button. Select/deselect the checkbox of the parameter in the add/remove parameter pop up box. Click on "Update" for the table to redraw with new selection of parameters.

  • Filter: Enter the desired value to filter parameter(s) by, and click the "Update Results" button to update the table display.

  • Reset Table: Click "Reset Table" to clear all filters/sorts and restore table back to default view.

  • Quick Filters: When applicable, select a quick filter with preset parameters filtered to narrow the results returned.

  • No Parts Returned: Adjust the filters on your least critical selection parameters in order to broaden your search.
