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 VREF amplifier makes output coupling capacitors unnecessary, and the motor governor uses a bridge ratio system to minimize the external 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.
