max4060/max4061/max4062 differential microphone preamplifiers with internal bias and complete shutdown _______________________________________________________________________________________ 9 fixed differential gain (max4060) the max4060 has an internal fixed gain of 10v/v for its differential input. this feature simplifies design, reduces pin count, footprint, and eliminates external gain-setting resistors. adjustable differential-gain setting the max4061/max4062 allow the user to alter the gain to optimize the signal-to-noise ratio (snr) of their sys- tem. the gain is set by a single external resistor (r g ) connected between the g1 and g2 pins, where: r g = 100k ? / (a v - 1) where a v is the required voltage gain. hence, an 11.11k ? resistor yields a gain of 10v/v, or 20db. leaving the pins unconnected results in a gain of 1v/v. gain for the max4061/max4062 is defined as: a v = v out / (v in+ - v in- ) the resistor can be either fixed or variable, allowing the use of a digitally controlled potentiometer to alter the gain under software control. input capacitors the two differential microphone inputs and the single- ended auxiliary input of the max4060/max4061/ max4062 have on-chip bias components, allowing the user to ac-couple any signals onto the input. the input resistance is 100k ? (typ), so the capacitor size may be chosen accordingly to define the lf rolloff desired. this can be calculated as: c in = 1 / (2 f cut r in ) this assumes a low source impedance driving the inputs. a further consideration for the differential input is the effect of these series input capacitors on low-frequency, common-mode rejection. any mismatch in the values of these two capacitors degrades the cmrr at frequen- cies where the impedance of the capacitor is significant compared to the input resistance of the amplifier?his is usually most noticeable at low frequencies. one way to avoid the need for matched or tight tolerance capaci- tors is to deliberately oversize the values on the differ- bias in- in+ 6 5 4 v cc 2.4v to 5.5v max4060 int/aux 1 out 2 gnd 7 bias 3 v bias bias x10 bias 8 aux_in x10 functional diagram

max4060/max4061/max4062 differential microphone preamplifiers with internal bias and complete shutdown ______________________________________________________________________________________ 11 max4061/max4062 the max4061/max4062 have a lower bias voltage and low-impedance outputs (optimum electret bias resistor can then be set externally). this gives a low-noise, flexi- ble solution that can run from 2.4v to 5.5v, suitable for hand-held devices such as pdas that typically have audio power supplies in the 3v region (see figure 3). in applications where the differential microphone is placed some distance from the max4060/max4061/ max4062, using a remote differential bias scheme as shown in figure 4 can provide improved noise rejection. output max4060/max4061 dc bias the output voltage has a dc-bias voltage independent of the power supplies, resulting in superior psrr per- formance. the max4061 output is high impedance when the part is in shutdown mode. ac-coupling the output into the next audio stage (e.g., codec) is rec- ommended. applications information shutdown mode the max4061 features a low-power, complete shut- down mode. when shdn goes low, the supply current drops to 0.3?, the output enters a high-impedance state, and the bias current to the microphone is switched off. driving shdn high enables the amplifier. shdn should not be left floating. power supplies and layout the max4060 operates from a 4.5v to 5.5v single sup- ply and the max4061/max4062 operate from a 2.4v to 5.5v single supply. bypass the power supply with a 0.1? capacitor to ground. in systems where analog and digital grounds are available, the max4060/ max4061 should be connected to the analog ground. in- in+ 6 5 4 v cc 4.5v to 5.5v max4060 int/aux 1 out 2 gnd 7 x10 v bias x10 bias 3 aux_in microphone input 8 r bias figure 2. max4060 used for biasing a microphone
