KA2184

The KA2184 is designed as a bipolar IC for the receiving pre-amplifier of infrared remote control systems. Typical functions include primary stage amplifier, limiter amplifier, BPF, signal waveform detecting and waveform shaping.

KA2184 has six features. (1)Low power consumption (Vcc=5V, 9mW typ). (2)Low power supply voltage (Vcc=5V). (3)Built-in filter (enables to vary center frequency with an extemally attached resister. fo=30KHz to 60KHz, 40KHz typ). (4)It is free from inductance due to magnetic field since it uses no L. (5)Possible to cirect connection to a photodiode. (6)Open collector output (possible to direct connection to TTL and CMOS). Those are all the main features.

Some absolute maximum ratings of KA2184 have been concluded into several points as follow. (1)Its power supply voltage would be +12V. (2)Its input voltage would be 5Vp-p (pin 1 output). (3)Its operating temperature range would be from -20°C to +75°C. (4)Its storage temperature range would be from -55°C to +150°C. (5)Its allowable power dissipation would be 0.4W. It should be known that stresses above the value listed in absolute maximum ratings may cause permanent damage to the device.

Also some electrical characteristics of KA2184 are concluded as follow. (1)Its Input pin voltage 1 would be min 2.0V and typ 2.5V and max 3.1V. (2)Its input pin voltage 2 would be min 0.6V and typ 1.0V and max 1.7V. (3)Its low level output voltage would be typ 0.2V and max 0.4V. (4)Its output leakage current would be typ 0uA and max 2.2uA. (5)Its voltage gain would be min 74dB and typ 79dB and max 84dB. (6)Its BPF characteristics would be min 4dB and typ 9dB. (7)Its input impedance would be typ 27k and typ 40k and max 55k. (8)Its consumption current would be min 1.0mA and typ 1.8mA and max 2.8mA. And so on. If you have any question or suggestion please contact us. Thank you!
