Pre / power amplifier and motor
governor for 3V headphone stereos
BA3528AFP / BA3529AFP
The BA3528AFP and AB3529AFP have been developed for headphone stereos. They run off a 3V power supply, and
include dual pre- and power amplifiers, and a motor governor.
The preamplifiers are direct-coupled, and the power amplifiers use a fixed-gain NF circuit. An on-chip V
REF
amplifier
makes output coupling capacitors unnecessary, and the motor governor uses a bridge ratio system to minimize the exter-
nal parts count and make reliable and compact designs possible.
FApplications
3V portable stereo equipment
FFeatures
1) All the functions required for headphone stereo units
on a single chip.
2) Preamplifier includes a mute amplifier.
3) Direct-coupled preamplifier.
4) No output coupling capacitors required for the power
amplifiers.
5) Power amplifiers do not require oscillation prevention
measures.
6) Power amplifier gain allows use of noise reduction
(BA3529AFP).
