New Japan Radio releases the NJM41030, 3dB video amplifier IC

August 31, 2009 - New Japan Radio Co., Ltd. has introduced to the market, the NJM41030, 3dB video amplifier IC, which realizes space saving and high reliability of video signal processing circuit in TV and Car-Navigation System.

[Background of development]

In video signal processing circuit of TV and car-navigation system, the video signal is usually handled as "1Vp-p amplitude". Therefore, the input signal to ADC*1 is required 1Vp-p amplitude. But sometimes there are DACs with 0.7Vp-p amplitude output signal. In that case, discrete circuit of 3dB amplifier is added, to convert 0.7Vp-p amplitude signal to 1Vp-p. New Japan Radio Co., Ltd. has developed the NJM41030, 3dB video amplifier IC to clear this inconvenience.

[Features]

1.Providing high reliability and space saving of the equipments
Employing the NJM41030, 3dB video amplifier IC, instead of conventional discrete circuit realizes reducing the number of parts, high reliability and 50 percent space reduction.
2.Providing stable gain
In discrete circuit, the deviation of gain is occurred by precision of resister used in the circuit. The NJM41030 provides the stable gain because of it's precision of resister built in chip.
3.Others
Built-in clamp circuit
Notes
