(7 pages)
The BA3513AFS is a dual, pre / power amplifier designed for headphone stereo applications. It has all of the basic signal
circuits required for tape players, and operates off a 3V supply.
The auto-reverse-compatible preamplifier block and fixed-gain power amplifier blocks are independent to facilitate noise
reduction.
The preamplifier block can be direct-coupled, and the power amplifiers do not require bootstrap capacitors, and use a
fixed-gain negative feedback circuit to reduce the number of external components required and allow compact and reli-
able set designs.
FApplications
3V headphone stereos and 3V radio cassette players.
FFeatures
1) Dual preamplifiers and power amplifiers on one chip.
2) Preamplifier suitable for auto-reverse use.
3) Transistor switch provided for metal-tape muting.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
