The KA2184 is designed as one kind of remote control receiving preamplifier circuit that can be used in the TV and video recoder applications. The internal circuit is composed of the preamplifier, the ABLC circuit, the amplitude limiting circuit, the bandpass filter, the wave detector, the comparator, the integrator, the Schmitt trigger. Features The power voltage is low (Vcc=5V).The power consumption is low, the typical value is 9mW when the typical value is 5V.It can be connected with the photosensitive diode directly.The collector is in the open-circuit output state, so you can connected it with the TTL and CMOS directly.It has the bandpass filter frequency selection filter.
