Hi Friends,
I am newbie for Opamp Design.
Could you please help me with the Opamp Different stages advantages/Disadvantages
Single stage, double stage and Triple stage.
Which would be good? Why?

Hi,
I would like to understand the Insertion Loss to % Conversion.
I know insertion loss is expressed in dB, While i could not able to calculate how much efficient my transformer is.
I have transformer with 0.75dB Insertion Loss.
Would love to understand the relation between Insertion Loss VS...
Hi Guys,
I have designed circuit with LM4755.
Speaker is 45ohm.
Voltage across Speaker is 5vrms.
VCC=16VDC
Can anyone help me with How to calculate the current passignG through LM4755??

Hi,
I am calculating stress analysis of IC
I need to understand the concept of Ambient Temperature?
Can Ambient temperature can be Min Ambient Temperature or Max Ambient temperature?

My speaker datasheet states that..
SPL=99dB (+6dB/-2dB) at 1 meter (Anechoic) with 2.83Vrms input.
Does it means that at 1W it gives 99dB?
V=2.83V
R=8 OHM
P=V^2/R=(2.83^2)/R=1W
so for 0.5W it will give 99dB-3dB=96dB
0.25W=93dB

Hi Schmitt
Thanks for your reply.
i was referring to some documents from PUIAUDIO, where they have clearly mentioned about the same.

Hi Technocrats,
Hope you are doing well in this Covid-19 pandemic situation.
I need your help for the Audio amplifier design.
Problem statement-to design audio amplifier which will able to produce 85dB outputs.
I have designed the Amplifier with TDA 1905 but i am not able to get the dB...
