The MAX9700AEUB+ is a single-supply audio power amplifier designed for a variety of audio applications like portable media players and mobile phones. The MAX9700 AEUB+ operates from a 4.2V to 5.5V single supply with a 60mW/channel output power into 32Ω load. It is capable of providing 1.2W/channel into 16Ω loads. This amplifier integrates an advanced boost converter that enables operation with a single or dual rail supply.

The high-performance MAX9700AEUB+ features a THD+N of –90dB, a SNR of 96dB, and an extended 20kHz frequency response. It also features a fast pop & click suppression scheme with an enable/disable control input.

The MAX9700AEUB+ almost eliminates the need for an external boost converter by supplying a PMOSFET driver, a high-voltage startup current source, and an overvoltage/overcurrent protection circuit with adjustable thresholds. This amplifier also integrates an internal thermal protection circuit.

The MAX9700AEUB+ is designed for very low power consumption. The amplifier provides a minimal 10μA quiescent current when the boost converter is disabled. When the input signals are high, the boost converter enables and it reduces the quiescent current to 25μA.

The MAX9700AEUB+’s exceptionally low EMI is enabled by its wide bandwidth output filters. The distortion and noise are averaged over a wide frequency range and thereby reduce the EMI.

The MAX9700AEUB+ is an ideal component for a portable amplifier application. It features a high efficiency and its wide dynamic range ensures superior audio quality.

Working Principle of the MAX9700AEUB+

The MAX9700AEUB+ utilizes a unique two-stage class-D amplifier architecture to provide excellent audio performance. The first stage amplifies the input signal and the second stage regenerates it to provide an output that is equal to the input signal with higher amplitude.

The MAX9700AEUB+ operates in a push-pull configuration to reduce distortion, reduce noise, and increase efficiency. The amplifier also utilizes a PMOSFET power switch to maximize power efficiency.

The MAX9700AEUB+ is designed with a low-noise folded-cascode circuitry, which enables it to maintain a low noise and high distortion performance across the entire audio frequency range. The amplifier also incorporates a low-noise linear voltage regulator to provide the necessary headroom to provide a high quality sound without clipping.

The MAX9700AEUB+ also features an integrated boost converter that can be enabled or disabled. The boost converter uses a switching voltage regulator to convert a lower input voltage to a higher output voltage, thus improving the efficiency of the amplifier.

The MAX9700AEUB+ also includes an over-current protection circuit with adjustable thresholds. This circuit monitors the current drawn by the amplifier and protects it from damage caused by excessive current.

The MAX9700AEUB+ can also be configured with a temperature sensor, which monitors the temperature of the amplifier and shuts down the amplifier when the temperature exceeds a predetermined threshold.

Application Field of the MAX9700AEUB+

The MAX9700AEUB+ is a great choice for audio applications where size, power efficiency and low noise are important. It is perfect for use in portable media players and mobile phones. It is also suitable for active speaker systems, battery-powered audio systems and multimedia applications.

The MAX9700AEUB+ can also be used in automotive applications, such as car stereos, amplifiers, audio processors, and speaker systems. Additionally, it can be used in home entertainment and AV systems, as well as audio mixing consoles and signal processors.
