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鈩?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
CC
= 6V and a 4鈩?/div>
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 鈥減op鈥?noise.
5) Excellent low voltage characteristics (starts operat-
ing at SV
t
2.8V).
