Laptop Headphone Jack Output Impedance

Laptop Headphone Jack Output Impedance. The impedance of your mobile’s audio. < 24 ω frequency response:

I would guess the headphone jack would be ok for any load 30 or 40 ohms or higher. Basically none of any of them. I avoided looking at the datasheet since the output impedance could also depend on the implementation.

This solution, although practical, is not the most efficient. Question on impedance (ohms) needed:

For example, the fiio e9 which uses the same tpa6120 has an output impedance of 10 on the large jack and an output impedance of 43 on the small jack. The amplifier that drives the headphone/line out jack is an audio amplifier chip.

It's a low(er) impedance output designed to drive tiny speakers. Thanks for the reply raja.

Headphones are typically about 32 ohms and line inputs are typically 10k. When viewed as a simple electronic circuit, the impedance of the audio source may be written as output (or source) impedance, while the impedance of the headphones may be considered load impedance.

For example, it should not have any trouble if the crossover was 100 kohms. I would guess the headphone jack would be ok for any load 30 or 40 ohms or higher.

It's a low(er) impedance output designed to drive tiny speakers. Then you can calculate the maximum power output at a given load impedance (p = u 2/z) and together with the sensitivity of the headphone you can determine whether it will make them go loud enough.

By Measuring The Output Voltage With No Load, And With A Known Load, You Can Calculate The Output Impedance.

The internal circuit will have an output impedance, and ideally you want your headphones to match that. Can i use in pc: For example, my dell has a conexant codec.

The Computer’s Sound Card Converts And Amplifies The Music.

Both of these things can be easily measured with a multimeter and a known resistor. Actually you want to aim for high impedance headphones if you don't know its output impedance. Even this several year old laptop can be set to work at 24 bit and all the normal sample rates up to 192 khz.

Three Subs/One Amp Varying Rms:

That chip is powered on an internal system voltage, likely on the order of ~6v. Headphones are typically about 32 ohms and line inputs are typically 10k. Think of it this way:

So I Assume That The Headphone Output Of Sound Cards Should Be Capable Of Driving A Load Of 8 Ohms.

At the pin is required to support 300mv at the jack with a 32ohm load and 1v with a 320 ohm load. < 24 ω frequency response: As it is now they mainly assume the amp is crap and if they have to do damping they have to do it acousticly rather than the right way wich would.

A Headphone Jack Does Not Output Line Level Audio Though;

It's a low(er) impedance output designed to drive tiny speakers. As a general rule of thumb, traditional headphone jack impedances are pegged pretty much between 0.1 ohms and 24 ohms. Microsoft allows device and system manufactures to limit output voltages to address eu safety.
