Hello,
We want to amplify the output current of our DAC in order to drive the phase shifters on the TripleX chip. Output specifications of the currently used DACs (current modules):
https://www.ni.com/docs/de-DE/bundle/ni-9265-specs/page/specs.html
https://www.ni.com/de-de/shop/hardware/products/c-series-current-output-module.html?modelId=122202
fmax = 100 kHz (max sampling freq. Of DAC)
Umax = 12 V
Imax = 20 mA
Desired output after the current amplifier:
fmax = 150 kHz (50 kHz safety)
RL = 600 Ohm (load resistance)
Umax > 25 V
Imax > 40 mA
I was thinking to use an OPAMP

Does someone know wich one will fit the best?
Cheers rza

if output should be +- 25V : https://www.ti.com/lit/gpn/opa454

didn't check the lead time 😉
