MAX4060EUA
Differential Microphone Preamplifiers with Internal Bias and Complete Shutdown
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 thin QFN
(3mm x 3mm x 0.8mm) and 8-pin µMAX packages. The
MAX4062 is available in a 10-pin µMAX package.

Pin Description
Detailed Description
The MAX4060/MAX4061/MAX4062 are differential micro-
phone preamplifiers providing high-quality audio, opti-
mized for use in computer and mobile applications.
These devices feature rail-to-rail outputs, very high
power-supply rejection, and common-mode rejection,
making them ideal for low-noise applications. The
MAX4060/MAX4061/MAX4062 are particularly effective
when layout constraints force the microphone amplifier to
be physically remote from the ECM microphone and/or
the rest of the audio circuitry.
The MAX4060/MAX4062 are capable of switching their
output between the differential input and an inverting
single-ended input. INT/AUX selects either the differen-
tial input or single-ended auxiliary input. In addition, the
MAX4060/MAX4061 have an internal bias generator to
bias the microphone in either differential or single-
ended modes. The MAX4061 includes a complete
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.
Differential Input
The main microphone input is a low-noise, differential
input structure. This is an almost essential element
when faced with amplification of low-amplitude analog
signals in digitally intense environments such as note-
book PCs or PDAs. Used correctly, the advantages
over a single-ended solution are:Better power-supply noise rejection.Less degradation from noise in PC board ground
planes.The microphone and preamplifier can be placed
physically further apart, easing PC board layout
restrictions.
MAX4060/MAX4061/MAX4062
Differential Microphone Preamplifiers with
Internal Bias and Complete Shutdown
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 (RG)
connected between the G1 and G2 pins, where:= 100kΩ/ (AV- 1)
where AVis the required voltage gain.
Hence, an 11.11kΩresistor 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:= VOUT/ (VIN+ - VIN-)
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 100kΩ(typ), so the capacitor size may be
chosen accordingly to define the LF rolloff desired. This
can be calculated as:
CIN= 1 / (2πfCUTRIN)
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—this 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-
