Class AB mono audio power amplifier module using a Hitachi HA13118 IC. High power output from a simple single rail low voltage DC supply using the Bridge Tied Load (BTL) method and providing a high gain of 55dB.
Especially useful in applications where the input signal level is low as it can be driven without requiring a separate preamplifier (e.g. a guitar practice amplifier or component car stereo amplifier). Will drive 4 or 8 Ohm speakers (not supplied).
