The LC2190 is designed as the infrared, ultrasonic and wireless remote control launch circuit that can be used in the air conditioner, electric fan, radio, TV and toy applications. The internal circuit is composed of the output driving circuit, the controllable oscillator, the timing cirucit, the coding pulse generator, the input latch circuit and the priority queuing circuit.etc. Features Low power consumption.Good anti-interference performance.Little external components.Easy to use.The external RC circuit forms the oscillating circuit. It does not need the crystal oscillator, so the cost of it is cheaper than other controllers.The matching model is LC2200.
