(K186)

designed for our CPS106 audio power
amplifier. It is also suitable for any power
amplifier module or circuit requiring a
positive and negative rail voltage of up to
45 Volts per side. The output voltage and
current will depend on the transformer
chosen, and this is not supplied with the
kit. Never use a transformer larger than
35V-0-35V, as the capacitors voltage
rating will be exceeded. (CPS186)

50W amplifier module TDA7294

The heart of this amplifier module is a monolithic integrated circuit from SGS-Thomson, TDA7294. It is intended for use as an audio class AB amplifier in hi-fi applications. It has a wide voltage range and output current capability, enabling it to supply the highest power into both 4 Ohm and 8 Ohm loads. With the addition of a handful of parts and a suitable power supply, this module will deliver > 50W RMS into 8 Ohm @ 0.1% THD. HEATSINK NOT INCLUDED. User must supply a heatsink rated at 1.4 deg C/W.
