DAC39J82：有高速电压信号转换成高速电流信号的方案吗

Hi,

This needs to be translated in order to support.

Our current solution is to use a high-speed DAC (DAC39J82) and an operational amplifier (OPA818) to output voltage signals. We would like to add an additional circuit (an external small circuit board) to convert the voltage signal into a current signal, with a bandwidth of 500MHz.

HI John,

Are there any additional details you could provide on the output current required. Will it be bipolar or unipolar? Also, the magnitude will be important. For really large current requirements, a larger power mosfet would likely be required which would make the bandwidth requirement extremely difficult.

Best Regards,

Ignacio
