BA3513AFS 3V dual pre / power amplifier

Audio ICs 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 .

Features

1) Dual preamplifiers and power amplifiers on one chip. 2) Preamplifier suitable for auto-reverse use. 3) Transistor switch provided for metal-tape muting. 4) Power amplifier gain is optimized for noise reduction. 5) Radiation prevention pin provided.
