Dear all,
I have to realize a simple circuit to split the line OUT from a sound card PC (green jack 3.5mm)
into two separate lines:
- one for standard headphones (stereo)
- one for line IN of a mixer/preamp (stereo)
People normally uses a Y-cable as splitter, but unfortunately it introduces some attenuation and
noise.
The power supply is provided by a standard USB port, so the voltage is 5 V±5% and
the typ. current should be 150mA (500 mA max).
I would like to realize a simple circuit based on AD op-amp but unfortunately I have no much
experience on analog and audio development.
I have found very interesting the AD822 Single-Supply, Rail-to-Rail Low Power FET-Input
Dual Op Amp, but unfortunately I have not even found an easy application note.
Can anyone suggest a particular AD devices, better if with technical notes ?
Thank you for your help.
Max
