MAX4060/MAX4061/MAX4062
Differential Microphone Preamplifiers with Internal Bias and Complete Shutdown
General Description
The MAX4060/MAX4061/MAX4062 are differential-input microphone preamplifiers optimized for notebook and PDA audio systems. These devices feature adjustable gain with excellent power-supply rejection and common-mode rejection ratios, making them ideal for lownoise applications in portable audio systems.
The MAX4060/MAX4062 are capable of switching their output between the differential input and a singleended auxiliary microphone amplifier input. In addition, the MAX4060/MAX4062 have a low-noise microphone bias generator. The differential gain of the MAX4061/MAX4062 is set with a single resistor.
