Following the discussion from this thread I am finalizing my calculations. I am not sure that I am calculating the power dissipation correctly. Given the following circuit
I need to operate the opamp between 0-2.4V in 100mV steps, sometimes holding the values for 30min. With
V_Emit=0.5V. The collectorcurrent reads
I_emit=0.043mA. At this conditions the Power loss calculates as
P_loss = (V_cc-V_Emit)*(I_c-I_emit)
I draw the power loss with the above formula over the range of
Can I choose the right transistor based on this calculation (max ~430uW)?
