SSM2380CBZ-REEL Application Field and Working Principle

The SSM2380CBZ-REEL is a high performance variable gain amplifier (VGA) designed specifically for audio applications. It is built on the proven Analog Devices variable gain amplifier architecture and offers the performance, flexibility and feature set needed to meet the requirements of the most challenging audio applications. The SSM2380CBZ-REEL is ideal for use in a variety of professional and consumer audio products, including portable audio players, gaming systems, car audio systems, and home entertainment systems.

Features of SSM2380CBZ-REEL

• Wide gain range: 0 dB to 40 dB
• Integrated automatic gain control (AGC)
• Integrated clip limiter
• Excellent signal-to-noise ratio (SNR): 98 dB
• Low distortion (THD+N): 0.001%
• Wide bandwidth: DC to 200 kHz

Applications of SSM2380CBZ-REEL

The SSM2380CBZ-REEL is a great choice for a wide range of audio applications. It is ideal for boosting the gain of low signal strength audio sources, such as microphone and instrument signals. The wide gain range of the SSM2380CBZ-REEL also makes it suitable for correcting the phase of signals or attenuating the level of strong audio signals without introducing distortion or noise.

The SSM2380CBZ-REEL can also be used in professional audio equipment such as mixing consoles and signal splitters, as well as in consumer audio equipment such as headphones and soundbars. The low distortion, high SNR, and wide bandwidth make the SSM2380CBZ-REEL a great choice for any audio application where high-quality sound is desired.

Working Principle of SSM2380CBZ-REEL

The SSM2380CBZ-REEL is a voltage-controlled amplifier that uses the principle of negative feedback to achieve its gain control range. The gain is determined by the applied voltage on the adjustment pin. A lower applied voltage will result in a lower gain, while a higher applied voltage will result in a higher gain. The SSM2380CBZ-REEL can be used either as a fixed gain amplifier or as a voltage-controlled amplifier.

The SSM2380CBZ-REEL features an integrated automatic gain control (AGC) circuit which can be used to keep the gain at a set level when there is a large change in the input signal level. This can be very useful in applications where the signal level may vary, such as in an audio recorder or a mixing console that has multiple inputs.

The integrated clip limiter on the SSM2380CBZ-REEL is used to reduce distortion by preventing the amplifier output from exceeding a predetermined level. This is especially important when dealing with high levels of gain, or when the input signal is of a very low level. The clip limiter can be adjusted to suit the application. By limiting the output level, the capacity for distortion is greatly reduced.

Conclusion

The SSM2380CBZ-REEL is a high performance VGA designed specifically for audio applications. It is ideal for boosting the gain of low signal strength audio signals, as well as for correcting the phase of signals or attenuating the level of strong audio signals. The SSM2380CBZ-REEL\'s wide gain range, integrated AGC and clip limiter, low distortion, high SNR, and wide bandwidth make it a great choice for any audio application where high-quality sound is desired.
