LE507 Datasheet | Unknown Manufacturer

FEATURES - 76 d B of gain - internal DC bias for I/P stage - applications include AF output stages, hearing aids and RF amplifiers - total harmonic distortion 1% (typical) STANDARD PACKAGING - 8 pin PLID ® - 8 pin DIP For ␣ more application information refer to Information Note 520 - 30. DESCRIPTION The LE507 is a low voltage class A amplifier design, primarily for low voltage and low power use. The broad application include AF output stages, RF amplifiers and output stages of the hearing instruments. The circuit is prised of three stages all of them having access to their collectors for frequency shaping, feedback, etc. The provision for the bias network and alternative gain increase to 76 d B are included on the circuit.
