D NTE Equivalent NTEA dual operational amp – Wholesale Electronics

I doubt it because most headphones today are 32 ohms. This amplifier might produce enough loudness in earphones to deafen you so maybe you will need an attenuator datasehet in series with each earphone. The RC is a dual opamp.

The low current BC and BC transistors will blow up if the output of the amplifier is shorted when it is playing loudly. Hierarchical block is unconnected 3. OpAmp help me with a simple audio amplifier. Equating complex number interms of the other 6.

So you can use it in any circuit. Its resistance will be a little less than its impedance. How reliable is it?

Measure its resistance with a multimeter. CMOS Technology file 1. Your earphone are probably 16 ohms for each ear so you need a little stereo power amplifier to drive them.

Instead it was designed to be the preamp in a record player or tape player that drives the inputs of a power amplifier. What is the impedance of your headphones?
