TA8173AP

The TA8173AP is the sound field reproduction IC developed for use on such stereo equipment as radio cassette tape recorder,multivoise TV set.etc.This IC has made it possible to reproduce stereophonic sound with more presence by forcing difference signals of R-ch and L-ch to delay and applying these signals to R-ch and L-ch again.

Features of the TA8173AP are:(1)built-in 4 stages of the lagging phase filter;(2)built-in normal/delay switch;(3)operating supply voltage range : VCC(opr)=4 to 12V (Ta=25).

The maximum ratings of the TA8173AP can be summarized as:(1):the characteristic is supply voltage,the symbol is VCC,the rating is 14,the unit is V;(2):the characteristic is power dissipation,the symbol is PD,the rating is 750,the unit is mW;(3):the characteristic is operating temperature,the symbol is Topr,the rating is -25 to 75,the unit is ;(4):the characteristic is storage temperature,the symbol is Tstg,the rating is -55 to 150,the unit is .
