Application Field: Audio Amplifiers

As part of the audio amplifiers family, the SSM2319CBZ-REEL provides an ideal solution for audio applications. It has been designed to provide the highest possible input and output levels, while also providing low distortion and low noise.The SSM2319CBZ-REEL operates in either stereo or mono configurations, with both distortion and output flexibility. It also provides excellent common-mode noise rejection and low input bias current, making it a great solution for audio applications with low noise requirements.

Enable High Dynamic Range and Low Noise

The SSM2319CBZ-REEL has been designed to provide high dynamic range and low noise performance. It operates on a rated power supply voltage of 5V, and provides a maximum output voltage of 22V. This ensures high dynamic range performance, and allows for low-noise operation.The SSM2319CBZ-REEL has a maximum input voltage of 2.4V and a minimum input voltage of 0.2V. This ensures that the amplifier can accurately convert audio signals without introducing noise or distortion. In addition, the SSM2319CBZ-REEL has a low input bias current of 9 µA and a low common-mode noise rejection of 80 dB. This ensures that the amplifier can accurately and faithfully convert audio signals while rejecting noise sources.

Working Principle

The SSM2319CBZ-REEL is an integrated amplifier circuit that is based on the System Building Blocks (SBB) architecture of Analog Devices. This architecture is used for both integrated amplifier circuits and for audio amplifiers. The SSM2319CBZ-REEL operates on a 5V power supply voltage and a maximum input voltage of 2.4V. The topology of this amplifier is based on an opamp-based non-inverting connection, with a single gain stage. This gain stage consists of a combination of an input buffer, two transimpedance gain stages, and an output buffer. The input buffer ensures that the amplifier is able to accurately capture audio signals. The two transimpedance gain stages represents the gain stage of the amplifier and enable the amplification of audio signals. Finally, the output buffer provides the required impedance matching of the output signals.

Conclusion

The SSM2319CBZ-REEL is a highly integrated amplifier circuit based on the System Building Blocks (SBB) architecture of Analog Devices. It is designed for audio applications, with a maximum input voltage of 2.4V and a maximum output voltage of 22V. It has a low input bias current of 9 µA and a low common-mode noise rejection of 80 dB, ensuring the accurate and faithful conversion of audio signals. The topology is based on an opamp-based non-inverting connection, with a single gain stage consisting of an input buffer, two transimpedance gain stages, and an output buffer. Overall, the SSM2319CBZ-REEL is an ideal solution for audio applications, providing excellent features for high dynamic range and low noise performance.
