383 audio ics 6v / 800mw single-channel power amplifier BA527 the BA527 is a monolithic power amplifier designed for portable cassette players and radio cassette players. with a 6v power supply, it has a rated output of 800mw into a 4 w load (thd = 10%). it is a high-grade design that generates almost no audible switching noise, and is ideal for high-end compact cassette players (including those with radio). applications portable cassette recorders and radio cassette recorders features 1) rated power output is 800mw (v cc = 6v and a 4 w load (thd = 10%). maximum output is 1300mw. 2) pin compatible with the rohm ba526 power amplifi- er, and can be interchanged to suit the application. 3) compact 9-pin sip package that does not require a heatsink. allows more compact set designs, and is easy to mount. 4) high ripple rejection ratio (55db) and generates al- most no apopo noise. 5) excellent low voltage characteristics (starts operat- ing at sv 2.8v). block diagram
