This is a stereo amplifier kit designed to make use of the STA540 power amplifier IC. Once this kit is completed you have a fully functional, two-channel audio amplifier, complete with a standby switch, volume control and indicator LEDs. The kit also includes a 6400BG heatsink for the STA540 to dissipate any damaging heat.
In this kit, the STA540 is configured as a dual bridge amplifier capable of delivering up to 2x 38W (4Ω at 18V). Power supplied to the kit directly powers the STA540 and should be within 8 to 22V.
