INTEGRATED CIRCUITS DATA SHEET TDA1514A 50 W high performance hi-fi amplifier Product specification File under Integrated Circuits, IC01 May 1992 Philips Semiconductors Product specification 50 W high performance hi-fi amplifier GENERAL DESCRIPTION TDA1514A 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 power · Low harmonic distortion · Low intermodulation distortion · Low offset voltage · Good ripple rejection · Mute/stand-by facilities · Thermal protection · Protected against electrostatic discharge · No switch-on or switch-off clicks · Very low thermal resistance · Safe Operating Area (SOAR) protection.
