AS3106KT - 50W Mono Hi-Fi Power Amplifier (TDA7294)

Ability Level 4: AdvancedProduct Formats Available: Pre-Assembled Module (AS) or
Self-Assembly Electronic Kit ( Soldering Required)

High power, hi-fi quality class AB audio amplifier module using a TDA7294 IC. This amazing little IC was designed for use in high quality hi-fi applications and has very low noise and distortion, wide bandwidth and good output current capability.

It provides an impressive 50W RMS into 8 Ohm or 82W RMS into 4 Ohm with only 0.1% THD.

Mute and Standby are brought out to connection pads on PCB. IC has internal short circuit and thermal protection, so is quite robust.

Space is provided on the PCB for mounting a 1.4° heatsink (not provided).

Can be combined with power supply module CFS007 or kit 3186 with a suitable mains transformer.

All components including IC insulation bush, screws, nuts & washers and TO-3 silicon-impregnated insulating washer are provided. Heat sink, speaker, cables and 30V power supply not provided.
