Description

FULL DATA SHEET (PDF, 152kB) Download   E-Mail The MAX4063 evaluation kit (EV kit) is a fully assembled and tested circuit board that uses the MAX4063 low-noise microphone amplifier IC designed for a single 2.4V to 5.5V application. The MAX4063 IC contains two microphone amplifiers. The main amplifier is typically used to sense an internal (built-in) system microphone, and an auxiliary amplifier that can be used to sense an external (plug-in) microphone. The differential and single-ended gains of the amplifiers are adjustable with jumpers and resistors. The differential output allows the EV kit to drive a load at up to 6VP-P. The EV kit also features low quiescent current and a shutdown control to minimize power consumption. The EV kit demonstrates how the MAX4063 can provide a complete microphone solution for a notebook PC. The MAX4063 is available in 14-pin TSSOP and 16-pin QFN (4mm x 4mm x 0.8mm) packages.
