The LM1877 is a monolithic dual audio power amplifier designed to deliver 2W/channel continuous into 8 Ohm loads. It was typically applicable in servo amplifiers, automotive products, tape recorders and players, AM-FM radio receivers, intercom system, multi-channel audio systems, and stereo phonographs.
The following article contains detail description of LM1877, its features, connection diagrams, equivalent schematic diagram, absolute maximum rating, LM1877 – Dual Audio Power Amplifier electrical characteristics (including total supply current, output power, total harmonic distortion, output swing, channel separation, PSRR power supply rejection noise, noise, open loop gain, input offset voltage, input bias current, input impedance, DC output level, Slew rate, power bandwidth, and current limit).
