The MAX4299EWP+ is an integrated circuit (IC) component designed for audio applications. This IC is a stereo headphone driver with an integrated microphone bias voltage converter. It offers various key features that make it ideal for use in portable audio devices, such as smartphones, tablets, and music players.
One key feature of the MAX4299EWP+ is its ability to drive stereo headphone loads from a single supply voltage. It can deliver high-quality audio output with a maximum output power of 75mW per channel into a 32-ohm load. This makes it suitable for driving low-impedance headphones or earphones.
Another important feature is its integrated microphone bias voltage converter. This allows the IC to provide a regulated bias voltage for electret condenser microphones. The built-in bias voltage generation simplifies the design and reduces the external component count required for microphone biasing.
Furthermore, the MAX4299EWP+ offers a wide range of input and output voltage capability. It can operate from a supply voltage as low as 1.8V, making it compatible with low-voltage battery-powered devices. The IC has a wide input common-mode range that extends beyond the supply voltage rails, enabling excellent audio performance.
In addition to these features, the MAX4299EWP+ provides protection mechanisms to safeguard against short circuits and thermal overload. It includes built-in short-circuit and thermal shutdown protection circuits that automatically disable the outputs when excessive current or temperature is detected
