Description:
The RC5502 is a stereo audio amplifier for use in directly
driving non-powered speakers. The RC5502 amplifier can
provide up to 3 watts of peak power into an 8 ohm speaker
load from a 12 volt supply. The gain of the RC5502 is user
defined by the selection of the appropriate feedback resis-
tors. The RC5502 has internal circuitry for the prevention of
“popping” with power-up/power-down and internal thermal
limiting circuitry.
