Abstract
A CMOS fully integrated headphone detector is presented in this paper. The circuit operation does not require any extra pin besides the output driver pins. It has detection capabilities for stereo loads, and works both in normal audio reproduction conditions and during the amplifier power-down mode. The power consumption of less than 9 muW, making the circuit highly suitable for portable audio equipment.
