I'm going to use a DAC8812 MDAC to scale a sine wave amplitude. I need a lot of swing and need to drive a big capacitive load, and the only opamp that I have that might work is THS6022. That's a 250 mA, 3 watt,300 MHz current-mode amp. I didn't expect that to work, but it does:
This is horrible abuse of a fast current-mode opamp.
The mdac data sheet says that the output capacitance is typically 50 pF but varies with DAC code. Thanks a lot.
It doesn't seem to need C2 but I guess I'll put a footprint on the PCB just in case. The impedance of that opamp's inverting input is 15 ohms, so that sort of shorts out the mdac output capacitance.
