IC for Headphone Stereos
Monolithic IC MM1376
Outline
This IC was developed for use in 3V headphone stereos, and combines all the basic audio circuitry for headphone stereos on a single chip. Recently hearing impairment caused by the high volumes of headphone stereos has become a problem, and there has been strong demand for functions for limiting loud volumes in the sets themselves. This IC incorporates an ALC circuit and has functions to hold the output from the headphone to a fixed level; it also eliminates the ordinary electronic governor circuit in order to accommodate trends toward thinner sets, as seen in the adoption of BSL motors.
