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 4Ω 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).

FApplications

Portable cassette recorders and radio cassette recorders

FFeatures

1) Rated power output is 800mW (V

= 6V and a 4Ω

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 “pop” noise.

5) Excellent low voltage characteristics (starts operat-

ing at SV

2.8V).
