Simple 50W Hi Fi amplifier with TDA7294

The TDA7294 is a Hi-Fi amplifier and can give 100W RMS but with 10% distortion. Supplying 30 Volts you can have 50 Watts RMS with 1% distortion. Frequency range start at 16Hz and can reach 100KHz. Make sure you are using good heatsink. The chip supports mute function as well.

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 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.
