EYE ON NPI - Analog Devices AD8460 110 V HV, 1A Arbitrary Waveform Generator @DigiKey @ADI_News

This week's EYE ON NPI is no arbitrary pick, it's Analog Devices' AD8460 110 V High Voltage, 1 A High Current

Either way you choose to run it, if you are planning on sinking or sourcing a significant amount of current - more than a few mA - you'll need to think hard about thermal management because if you're handling 100mA at 30V that's 3W and a plain TQFP is not designed for that. The TQFP does have a big thermal pad on top. Use that to attach a chonky sink and fan as needed for your expected wattage needs. FYI, there is power / over-heat alarms available to configure on the chip in case you need to warn the user or dial down the voltage.

Sounds like an interesting device! If one wanted to extend the output, to say a build an HV AWG volts capable of a few hundred volt swing - would it be possible to combine several of these in series with some other circuitry? The datasheet didn't seem to mention a use of this type.
