BA3528AFP Pre / power amplifier and motor governor for 3V headphone stereos

Audio ICs 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 ex.
