MAX4167
High-Output-Drive, Precision, Low-Power, Single-Supply, Rail-to-Rail I/O Op Amps with Shutdown
General DescriptionThe MAX4165–MAX4169 family of operational amplifiers
combines excellent DC accuracy with high output current
drive, single-supply operation, and rail-to-rail inputs and
outputs. These devices operate from a single +2.7V to
+6.5V supply, or from dual ±1.35V to ±3.25V supplies.
They typically draw 1.2mA supply current, and are guar-
anteed to deliver 80mA output current.
The MAX4166/MAX4168 have a shutdown mode that
reduces supply current to 38µA per amplifier and
places the outputs into a high-impedance state. The
MAX4165–MAX4169’s precision performance com-
bined with high output current, wide input/output
dynamic range, single-supply operation, and low power
consumption makes them ideal for portable audio
applications and other low-voltage, battery-powered
systems. The MAX4165 is available in the space-saving
5-pin SOT23 package and the MAX4166 is available in
a tiny 2mm x 2mm x 0.8mm µDFN package.

Applications Information
Package Power Dissipation
Warning: Due to the high output current drive, this op
amp can exceed the absolute maximum power-dissi-
pation rating.As a general rule, as long as the peak cur-
rent is less than or equal to 80mA, the maximum package
power dissipation will not be exceeded for any of the
package types offered. There are some exceptions to this
rule, however. The absolute maximum power-dissipation
rating of each package should always be verified using
the following equations. The following equation gives an
approximation of the package power dissipation:
where:VRMS= the RMS voltage from VCCto VOUT
when sourcing currentthe RMS voltage from VOUTto VEE
when sinking current
IRMS= the RMS current flowing out of or into
the op amp and the load= the phase difference between the
voltage and the current. For resistive
loads, COS q= 1.
For example, the circuit in Figure 1 has a package
power dissipation of 157mW.
Therefore, PIC(DISS)= VRMSIRMSCOS q
= 157mW
Adding a coupling capacitor improves the package
power dissipation because there is no DC current to
the load, as shown in Figure 2.
Therefore, PIC(DISS)= VRMSIRMSCOS q
= 38.6mW
The absolute maximum power-dissipation rating of this
package would be exceeded if the configuration in
Figure 1 were used with all four of the MAX4169ESD’s
amplifiers at a high ambient temperature of +75°C
(157mW x 4 amplifiers = 628mW + a derating of
8.33mW/°C x 5°C = 669mW). Note that 669mW just
exceeds the absolute maximum power dissipation of
667mW for the 14-pin SO package (see the Absolute
Maximum Ratingssection). V V + I
