MAX4062 General Description
The MAX4060/MAX4061/MAX4062 are differential-inputmicrophone preamplifiers optimized for notebook andPDA audio systems. These devices feature adjustablegain with excellent power-supply rejection and com-mon-mode rejection ratios, making them ideal for low-noise applications in portable audio systems.
The MAX4060/MAX4062 are capable of switching theiroutput between the differential input and a single-ended auxiliary microphone amplifier input. In addition,the MAX4060/MAX4062 have a low-noise microphonebias generator. The differential gain of theMAX4061/MAX4062 is set with a single resistor. TheMAX4060 has a fixed gain of 10V/V and is PC99/2001compliant. The MAX4061 includes a complete shut-down mode. In shutdown, the supply current isreduced to 0.3µA and the current to the microphonebias is cut off for ultimate power savings.
The MAX4060 operates from a 4.5V to 5.5V single sup-ply and the MAX4061/MAX4062 operate from 2.4V to5.5V. All devices are specified over the extended oper-ating temperature range, -40°C to +85°C. TheMAX4060/MAX4061 are available in tiny 8-pin thin QFN(3mm x 3mm x 0.8mm) and 8-pin µMAX packages. TheMAX4062 is available in a 10-pin µMAX package.
