TDA1514 alone can provide 50 watts of power supply voltage and a maximum of + – 30 volts mute / stantby temperature protection, overcurrent protection feature. Amp circuit with a few passive components can
TDA1514 Amplifier Circuit
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 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.
· 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.
