I need to calculate the max power in mw for a Cmoy design using an opa2134 opamp.
The opa2134 datasheet states that the max current by channel is 35mA.
I'm using this formula:
P = I^2 * R = ((0.035)^2) * 16 = 0.0196 W = 19.6 mw @ 16 Ohm
P = I^2 * R = ((0.035)^2) * 32 = 0.0392 W = 39.2 mw @ 32 Ohm
I have seen on datasheets that the Power Output raises when the load decreases, but with this calculation the power from a Load
of 16 to a load of 32 ohm is increasing.
Is there any error on the calculation?
