3V dual pre / power amplifier
BA3513AFS
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 reliable set designs.
FApplications 3V headphone stereos and 3V radio cassette players.
FFeatures 1) Dual preamplifiers and power amplifiers on one chip.
