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 (VCC = 6V and a 4Ω load (THD = 10%).
Maximum output is 1300mW.

com 2) Pin compatible with the Rohm BA526 power amplifier, 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 almost no “pop” noise.
5) Excellent low voltage characteristics (starts operating at SV t 2.
8V).
