Part Number: OPA836
Other Parts Discussed in Thread: OPA838, , OPA837

Hi team,

My customer is using our OPA836 & OPA838 now.

And they wonder if we have a newer device to recommend.

Requirements:

BW: >200MHz

slew rate:>200V/us

Iq:<1mA

Thanks,

Brian

Hi Brian,

The OPA838 is still the best device to consider for this requirement. The OPA838 being a decompensated amplifier gives an excellent figure of merit with its very high 300 MHz GBW, 350V/us slew rate while consuming only 0.95 mA quiescent current.

Regards,

Bharat Agrawal

but for the OPA836, you might look at the OPA837 which was the unity gain stable version of the OPA838
