The MAX218EAP+ is an integrated circuit (IC) component manufactured by Maxim Integrated Products. It is a low-cost, two-channel audio power amplifier designed for applications that require a compact and robust solution. The IC operates on a single supply voltage ranging from 4V to 5.5V, making it suitable for battery-powered devices.
The key features of the MAX218EAP+ include its high output power capability and low power consumption. It can deliver a maximum output power of 1.1 watts per channel into an 8-ohm load with less than 1% total harmonic distortion. The low power consumption ensures efficient utilization of the available power source, extending battery life for portable applications.
Another significant feature of the MAX218EAP+ is its wide input voltage range. It can accept input voltages from 0.9V to VDD, allowing for compatibility with different input signals. Additionally, the chip incorporates an internal gain setting resistor to simplify the design process and reduce external component count.
This IC also offers thermal and short-circuit protection, ensuring reliable and safe operation. The thermal protection prevents the amplifier from overheating, while the short-circuit protection safeguards the device from potential damage in case of a short-circuit condition.
Furthermore, the MAX218EAP+ integrates a mute function controlled by the shutdown pin. This feature allows the user to disable the amplifier when needed, conserving power and reducing any unwanted audio output
