Working Principle of AD8398ACPZ-R7

The AD8398ACPZ-R7 is a single-channel, high-performance, low-power Class D output amplifier designed to operate with a wide range of power supply voltage and a wide range of output voltage. It is designed to drive a 4Ω load with a maximum output voltage of 818 mV RMS and deliver up to 300 W into 4Ω with excellent power efficiency and distortion performance. The device is a switching amplifier that uses pulse-width modulation to convert an input signal into an output signal with high efficiency. It operates with a wide input signal range from 0 to 20 kHz and delivers up to 300 W with only 10% THD+N. The AD8398ACPZ-R7 offers excellent PSRR performance, high SNR performance, and protection features such as thermal overload and short-circuit protection.

The AD8398ACPZ-R7 is based on the standard Class D design eskepin which the output is modulated by an input signal. The output signal can also be modulated by an external clock input to provide variable pulse-width modulation (PWM). The output of the PWM signal is then used to switch between two transistors to control the output voltage. The transistors are connected in a bridge configuration to ensure that no dc current flows through the output and to maximize power efficiency. In addition, the AD8398ACPZ-R7 includes a low-pass filter to reduce distortion and noise at the output.

The AD8398ACPZ-R7 can be used in a variety of audio applications such as loudspeaker systems, active crossovers and high-end hi-fi audio systems. It delivers excellent power efficiency, distortion performance and output voltage control. The device is also protected against short-circuits and thermal overload. Its compact package and low-power architecture make it ideal for use in mobile and battery-powered systems.
