... The microphone and preamplifier may be placed physically further apart, easing PC board layout restrictions. Differential-Gain Adjustment The MAX4063 allows the user to alter the differential gain to optimize the signal-to-noise ratio (SNR) of their system. The gain is set by a single external resistor (R ) connected between the G1 and G2 pins: G Ω ...

... AUX_IN and ADJ. ADJ The two differential microphone inputs and the single- ended auxiliary input of the MAX4063 have on-chip bias components, allowing the user to AC-couple any signals into the input. The input resistance is 100kΩ (typ), so the capacitor size may be chosen accordingly to define the LF rolloff desired ...
