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).
