SSM2518CPZ application field and working principle

The SSM2518CPZ is a next-generation, ultra-wideband, low-distortion audio amplifier produced by Analog Devices. This device is designed to produce audio signals with low levels of distortion and high levels of power. Furthermore, the SSM2518CPZ is designed to drive a wide variety of loads, including both single- and multi-channel audio systems. The SSM2518CPZ can be used in a wide range of applications, including home audio systems, headphone amplifiers, and automotive audio systems.The SSM2518CPZ is an audio amplifier that provides amplification from DC up to 400kHz and operates from a single supply voltage from 4V to 20V. It comprises two wideband, low-distortion, low-noise audio amplifiers armed in a single package, each one offering a maximum power output of 800mW into 600Ω load. Each amplifier is capable of providing up to 1.2A of peak current with a 2.5Vp peak-to-peak supply voltage.The SSM2518CPZ is designed to drive a wide variety of audio sources, including speakers, headphones, small speakers, or even large pa systems. It offers an adjustable level of gain from 0dB to +24dB and includes zero-crossing detectors to protect against pop and clicks. The SSM2518CPZ also offers a variety of control features, such as mute control, standby control, and output short circuit protection.The SSM2518CPZ audio amplifier works on a principle known as pulse density modulation (PDM), where the signal is modulated with a pulse-width-modulated (PWM) signal. This signal is then fed to a temporary storage circuit known as a charge pump, which stores energy from the signal and then passes it on to the output. The SSM2518CPZ has the capability to accurately reproduce the audio signal without the need for an analog signal to gain or offset.In summary, the SSM2518CPZ audio amplifier is a versatile and powerful amplifier designed to drive a wide variety of audio sources. It offers an impressive 0.0003% total harmonic distortion, a low 0.05% noise figure, and adjustable level of gain from 0dB to +24dB. It also offers a variety of control features, such as mute control, standby control, and output short circuit protection. The SSM2518CPZ is a great choice for a variety of audio applications.
