Product Details

The MAX4060 evaluation kit (EV kit) is a fully assembled and tested circuit board used to evaluate the MAX4060 low-noise microphone amplifier. The MAX4060 contains a differential input amplifier typically used for an internal microphone and a single-ended auxiliary-input amplifier used for an external microphone. Both amplifiers have an internally set fixed gain of 10V/V. The MAX4060 EV kit also provides a bias voltage for powering microphones, compliant with the PC99/2001 specification.

The MAX4060 EV kit has low quiescent current and high power-supply rejection. The MAX4060 is available in 8-pin QFN and µMAX® packages. The MAX4060 EV kit uses the smaller 8-pin QFN package.
