50W Audio Power Amplifier

50 W high performance hi-fi amplifier

GENERAL DESCRIPTION

The TDA1514A integrated circuit is a hi-fi power amplifier for use as a building block in radio, tv and other audio applications. The high performance of the IC meets the requirements of digital sources (e.g. Compact Disc equipment). The circuit is totally protected, the two output transistors both having thermal and SOAR protection (see Fig.3). The circuit also has a mute function that can be arranged for a period after power-on with a delay time fixed by external components. The device is intended for symmetrical power supplies but an asymmetrical supply may also be used.
Features High output powerLow harmonic distortionLow intermodulation distortionLow offset voltageGood ripple rejectionMute/stand-by facilitiesThermal protectionProtected against electrostatic dischargeNo switch-on or switch-off clicksVery low thermal resistanceSafe Operating Area (SOAR) protection.Circuit Diagram for 50 W high performance hi-fi amplifier:
