BA3529AFP 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. .

Features

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).
