1 / 15 page 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 com- mon-mode rejection ratios, making them ideal for low- noise applications in portable audio systems. The MAX4060/MAX4062 are capable of switching their output between the differential input and a single- ended 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. The MAX4060 has a fixed gain of 10V/V and is PC99/2001 compliant. The MAX4061 includes a complete shut- down mode. In shutdown, the supply current is reduced to 0.3µA and the current to the microphone bias 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 to 5.5V. All devices are specified over the extended oper- ating temperature range, -40°C to +85°C. The MAX4060/MAX4061 are available in tiny 8-pin TDFN (3mm x 3mm x 0.8mm) and 8-pin µMAX® packages. The MAX4062 is available in a 10-pin µMAX package.
