MAX9727EEP+ is a low-power, low-voltage, low-noise audio power amplifier and can support up to 0.5W of output power into a 16-Ohm load with a 5V power supply. This makes it ideal for portable applications such as cell phones, media players, and portable gaming devices. The MAX9727EEP+ also offers impressive dynamic range and low distortion performance at typical audio frequencies. The MAX9727EEP+ is a versatile amplifier and can be used in mono or stereo applications.

The MAX9727EEP+ utilizes an extended power stage circuit topology to obtain performance. The three-stage design consists of a class AB input stage, dual complementary class AB output stages, and a class D Feedback circuit. The input stage is used to adjust the voltage gain of the device and is adjustable to better match the supply voltage and load impedances. The dual class AB output stages then drive the load, while the class D feedback circuit provides negative feedback, which reduces distortion and increases efficiency while maintaining low noise performance.

The MAX9727EEP+ has a typical gain of 20dB, and the input signals can be balanced or unbalanced as required. The amplifier is powered by a 5.0V power supply and requires a minimum voltage of 2.7V for proper operation. It offers an integrated thermal and input protection circuit to ensure reliable performance. The amplifier has a typical idle current of 22mA and an adjustable output current limit of up to 300mA. The MAX9727EEP+ has a typically power supply ripple rejection of 77dB at 50 Hz and a minimum loaded output power of 0.25W into 16 ohms.

The MAX9727EEP+ offers excellent performance and is ideal for portable audio applications. Its small size and low power requirements make it ideal for use in battery-powered and space-constrained applications. Its excellent dynamic range and low distortion performance make it well-suited for any audio application that needs quality audio with minimal power consumption.
