... Gain-Selectable Input. Connect an external resistor between G1 and G2 to set G1 the gain for the differential amplifier. 0.3µA shutdown mode for ultimate power savings. The differential gain of the MAX4061/MAX4062 is set with a single resistor connected between the G1 and G2 pins. The MAX4060 has a fixed gain of 10V/V. The main microphone input is a low-noise, differential input structure ...

... A DM mode gain. Input voltages are sufficiently small such that the output is not clipped in either differential or common-mode application. The topology used in the MAX4061/ MAX4062 means that the CMRR actually improves at higher differential gains—another advantage of using differential sensing. 10 ______________________________________________________________________________________ 2 ...
