The MAX4063 is a differential-input microphone preamplifier optimized for high-performance, portable applications. The device features two selectable inputs, differential outputs, adjustable gain, an integrated low-noise bias source, and a low-power shutdown mode. Two input paths provide both differential and single-ended microphone sensing. The high-noise rejection of the differential input is ideally suited to an internal microphone where system noise and long-run PC board traces can degrade low-level signals. The single-ended input provides a simple connection to an external microphone.

The differential and single-ended inputs have independent, adjustable gains that are set with a single external resistor. Differential outputs provide a full-scale signal of up to 6V_P-P from a single 3V supply, optimizing the dynamic range of the amplified signal. A complete shutdown mode reduces the supply current to only 0.3µA and disables the microphone bias for the ultimate in power savings.

The MAX4063 operates from 2.4V to 5.5V and is specified over the extended -40°C to +85°C operating temperature range. The MAX4063 is available in both 16-pin TQFN (4mm x 4mm x 0.8mm) and 14-pin TSSOP packages.

Product Details

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 6V_P-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.
