Nisshinbo Micro Devices Inc. Linear - Linear - Video Processing - NJM2279D NJM2279D

The NJM2279D is a 3-input, 2-output video switch designed for audio-visual applications. It features an internal 6dB amplifier and a 75,Ѷ driver circuit, allowing for direct connection to TV monitors. The device includes a mute function for both outputs and operates with dual supply voltages ranging from ¬±4V to ¬±7V or a single supply of +8V to +14V. The NJM2279D has a power dissipation rating of 700mW in a DIP14 package and operates within a temperature range of -20¬8C to +75¬8C. Key electrical characteristics include a typical operating current of 17.3mA at ¬±5V, a voltage gain of approximately 6.3dB, and a total harmonic distortion of less than 0.1%. The input impedance is 20k,Ѷ, and the device exhibits low crosstalk levels, making it suitable for high-quality video switching applications.
