MAXIM MAX4167ESA

19-1224; Rev 3; 1/0 7
High-Output-Drive, Precision, Low-Power, SingleSupply, Rail-to-Rail I/O Op Amps with Shutdown
The 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 guaranteed 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 combined 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Package Power Dissipation
Warning: Due to the high output current drive, this op
amp can exceed the absolute maximum power-dissipation rating. As a general rule, as long as the peak current 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:

PIC(DISS) ≅ VRMS IRMS COS θ
where: VRMS = the RMS voltage from VCC to VOUT
when sourcing current
= the RMS voltage from V OUT to V EE
when sinking current
IRMS = the RMS current flowing out of or into
the op amp and the load
θ = the phase difference between the
voltage and the current. For resistive
loads, COS θ = 1.
For example, the circuit in Figure 1 has a package
power dissipation of 157mW.

the load, as shown in Figure 2.

The absolute maximum power-dissipation rating of this

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 Ratings section).

Single-Supply Speaker Driver
The MAX4165/MAX4166 can be used as a single-supply speaker driver, as shown in the Typical Operating
Circuit. Capacitor C1 is used for blocking DC (a 0.1µF
ceramic capacitor can be used). When choosing resistors R3 and R4, take into consideration the input bias
current as well as how much supply current can be tolerated. Choose resistors R1 and R2 according to the
amount of gain and current desired. Capacitor C3
ensures unity gain for DC. A 10µF electrolytic capacitor
is suitable for most applications. The coupling capacitor C2 sets a low-frequency pole and is fairly large in
value. For a 32Ω load, a 100µF coupling capacitor
gives a low-frequency pole at 50Hz. The low-frequency
pole can be set according to the following equation:
ƒ = 1 / 2π (RLC2)
Bridge Amplifier
The circuit shown in Figure 3 uses a dual MAX4167/
MAX4168 to implement a 3V, 200mW amplifier suitable
for use in size-constrained applications. This configuration eliminates the need for the large coupling capacitor required by the single op-amp speaker driver when
single-supply operation is a must. Voltage gain is set to
+10V/V; however, it can be changed by adjusting the
900kΩ resistor value. DC voltage at the speaker is limited to 10mV. The 47Ω and 0.1µF capacitors across the
speaker maintain a low impedance at the load as frequency increases.

Rail-to-Rail Input Stage
Devices in the MAX4165–MAX4169 family of high-output-current amplifiers have rail-to-rail input and output
stages designed for low-voltage, single-supply operation. The input stage consists of separate NPN and
PNP differential stages that combine to provide an
input common-mode range that extends 0.25V beyond
the supply rails. The PNP stage is active for input voltages close to the negative rail, and the NPN stage is
active for input voltages near the positive rail. The
switchover transition region, which occurs near VCC / 2,
has been extended to minimize the slight degradation
in common-mode rejection ratio caused by mismatch of
the input pairs.
______________________________________________________________________________________

MAX4165–MAX4169
1kΩ
1kΩ
Since the input stage switches between the NPN and
PNP pairs, the input bias current changes polarity as the
input voltage passes through the transition region. Match
the effective impedance seen by each input to reduce the
offset error caused by input bias currents flowing through
external source impedances (Figures 4 and 5).
High source impedances, together with input capacitance, can create a parasitic pole that produces an
underdamped signal response. Reducing the input
impedance or placing a small (2pF to 10pF) capacitor
across the feedback resistor improves response.
The MAX4165–MAX4169’s inputs are protected from large
differential input voltages by 1kΩ series resistors and
back-to-back triple diodes across the inputs (Figure 6).
For differential voltages less than 1.8V, input resistance is
typically 500kΩ. For differential input voltages greater
than 1.8V, input resistance is approximately 2kΩ. The
input bias current is given by the following equation:
IBIAS = (VDIFF - 1.8V) / 2kΩ
Rail-to-Rail Output Stage
The minimum output is within millivolts of ground for
single-supply operation, where the load is referenced
to ground (VEE). Figure 7 shows the input voltage range
and the output voltage swing of a MAX4165 connected
as a voltage follower. The maximum output voltage
swing is load dependent; however, it is guaranteed to
be within 430mV of the positive rail (VCC = 5V) even
with maximum load (25Ω to ground).

Driving Capacitive Loads
The MAX4165–MAX4169 have a high tolerance for
capacitive loads. They are stable with capacitive loads
up to 250pF. Figure 8 is a graph of the stable operating
region for various capacitive loads vs. resistive loads.
Figures 9 and 10 show the transient response with
excessive capacitive loads (1500pF), with and without
the addition of an isolation resistor in series with the
output. Figure 11 shows a typical noninverting capacitive-load-driving circuit in the unity-gain configuration.
The resistor improves the circuit’s phase margin by isolating the load capacitor from the op amp’s output.

Power-Up and Shutdown Modes
The MAX4166/MAX4168 have a shutdown option.
When the shutdown pin (SHDN) is pulled low, supply
current drops to 58µA per amplifier (VCC = +5V), the
amplifiers are disabled, and their outputs are placed in
a high-impedance state. Pulling SHDN high or leaving it
floating enables the amplifier. In the dual MAX4168, the
two amplifiers shut down independently. Figures 12
and 13 show the MAX4166’s output voltage and supply-current responses to a shutdown pulse. The
MAX4166–MAX4169 typically settle within 5µs after
power-up (Figure 14).

Figure 11. Capacitive-Load-Driving Circuit
Power Supplies and Layout
The MAX4165–MAX4169 can operate from a single
+2.7V to +6.5V supply, or from dual ±1.35V to
±3.25V supplies. For single-supply operation, bypass
the power supply with a 0.1µF ceramic capacitor in
parallel with at least 1µF. For dual-supply operation,
bypass each supply to ground. Good layout improves
performance by decreasing the amount of stray capacitance at the op amps’ inputs and outputs. Decrease
stray capacitance by placing external components
close to the op amps’ pins, minimizing trace and lead
lengths.
