TDA1514A  g eneral description: Here the very simple but powerful amplifier kit which built based on TDA1514A amplifier chip. The circuit is for single channel only, you should build two similar circuit for stereo application. A heatsink is a must to be attached on the IC TDA1514A. This circuit can be used as well as stereoamplifiers Bass in a 5.1 system.  TDA1514A Audio Amplifier 50W TDA1514A  features : Battery operation Minimum external parts Wide supply voltage range: 4V–12V or 5V–18V Low quiescent current drain: 4mA Voltage gains from 20 to 200 Ground referenced input Self-centering output quiescent voltage Low distortion: 0.2% (AV = 20, VS = 6V, RL = 8Ω, PO = 125mW, f = 1kHz) Available in 8 pin MSOP package TDA1514A  circuit : TDA1514A Audio Amplifier 50W TDA1514A  layout : Printed Circuit Layout and placement for mono 40 W amplifier: TDA1514A Audio Amplifier 50W pcb TDA1514A Audio Amplifier 50W la...

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 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.
