Product details

What the integrated features mean for your BOM

The input multiplexer allows switching between two microphone sources or a line input without an external analog switch — saves one IC and the associated routing. Shutdown control reduces quiescent draw when the audio path is idle, which matters for battery-powered products where every milliampere-hour counts. Thermal protection prevents latch-up or damage if the output is shorted or driven into a low-impedance load at elevated ambient temperatures.

Frequently asked questions

What is the typical application for MAX9813LEKA+T?

The MAX9813LEKA+T is a Class AB mono amplifier with an integrated input multiplexer and microphone bias, designed for microphone-input applications such as portable audio devices, intercoms, voice recorders, and handheld communication gear.

What external components are needed for MAX9813LEKA+T?

As a general guideline, a microphone-input amplifier typically requires input coupling capacitors, supply bypass capacitors, and output coupling capacitors. The integrated microphone bias and input mux reduce the external component count compared to discrete implementations. Refer to the MAX9813 datasheet for the exact recommended application circuit.

Is MAX9813LEKA+T suitable for microphone input?

Yes, the part includes an input multiplexer and microphone bias specifically for microphone-input applications, making it suitable for electret or MEMS microphone front-ends.
