A high quality audio-amp in a 5-pin TO220 package that does not require insulating washers between the metal tab and heatsink in single rail supply applications. The amp will operate with single or split supplies. The amp can provide 32W rms into a 4 load and 25W rms into 8. The device features low harmonic and crossover distortion and a low external component count. The device includes short circuit protection and thermal shutdown.Specifications: |
