Dual preamplifier with ALC detector circuit
BA3314F
The BA3314F is a dual preamplifier IC with built-in ALC detector circuit, designed for audio applications. It comes in a compact 14-pin SOP package, and has two record / playback preamplifiers, and an ALC detector circuit. The preamplifier can be directly coupled to the tape head without coupling capacitors to prevent tape head magnetization and “pop” noise generation. With the built-in ALC detector circuit, an ALC circuit with large dynamic range can be constructed with addition of just an external time constant circuit. FApplications Audio equipment FFeatures 1) Input bias circuit does not require coupling capacitors. 2) Built-in ALC circuit with external time constant circuit.
