The post 50W Audio Amplifier with TDA1514A first appeared on Electronic Schematic Diagram.]]> Here the another audio amplifier circuit with single power IC from Phillips, TDA1514A. This is a hi-fi power amplifier circuit with 50W power output. A power IC delivers 50W single power output, then you need to build two similar circuit for stereo application.

50W Audio Amplifier with 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 (dual polarity) power supplies but an asymmetrical supply may also be used.

TDA1514A 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.

The post 50 Watt Power Audio Amplifier first appeared on Electronic Schematic Diagram.]]> Here the circuit diagram of 50W power amplifier. The amplifier uses a pair of power transistors that are MJ2955 and 2N3055 to amplify the input signal. You must use a heatsink on those transistors. The below design diagram uses for single input/output channel, just built two similar circuit to make it dual channel (stereo).
