♦ 80mA (min) Output Drive Capability
♦ Rail-to-Rail Input Common-Mode Voltage Range
♦ Rail-to-Rail Output Voltage Swing
♦ 1.2mA Supply Current per Amplifier
♦ +2.7V to +6.5V Single-Supply Operation
♦ 5MHz Gain-Bandwidth Product
The MAX4165–MAX4169 family of operational ampli-
fiers combines excellent DC accuracy with high output
®
current drive, single-supply operation, and Rail-to-Rail
inputs and outputs. These devices operate from a sin-
gle +2.7V to +6.5V sup ply, or from dua l ± 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
re d uc e s s up p ly c urre nt to 38µA p e r a mp lifie r a nd
places the outputs into a high-impedance state. The
MAX4165–MAX4169’s p re c is ion p e rforma nc e c om-
b ine d with hig h outp ut c urre nt, wid e inp ut/outp ut
dynamic range, single-supply operation, and low power
c ons ump tion ma ke s the m id e a l for p orta b le a ud io
applications and other low-voltage, battery-powered
systems. The MAX4165 is available in the space-saving
5-pin SOT23 package.
♦ 250µV Offset Voltage
♦ 120dB Voltage Gain (R = 100kΩ)
L
♦ 88dB Power-Supply Rejection Ratio
♦ No Phase Reversal for Overdriven Inputs
♦ Unity-Gain Stable for Capacitive Loads to 250pF
♦ Low-Power Shutdown Mode:
Reduces Supply Current to 38µA
Places Outputs in High-Impedance State

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.

The MAX4165/MAX4166 can be used as a single-sup-
ply 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 resis-
tors R3 and R4, take into consideration the input bias
current as well as how much supply current can be tol-
erated. Choose resistors R1 and R2 according to the
a mount of g a in a nd c urre nt d e s ire d . Ca p a c itor C3
ensures unity gain for DC. A 10µF electrolytic capacitor
is suitable for most applications. The coupling capaci-
tor 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:

Devices in the MAX4165–MAX4169 family of high-out-
put-current amplifiers have rail-to-rail input and output
stages designed for low-voltage, single-supply opera-
tion. 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 volt-
ages close to the negative rail, and the NPN stage is
active for input voltages near the positive rail. The

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 configura-
tion eliminates the need for the large coupling capaci-
tor 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 limit-
ed to 10mV. The 47Ω and 0.1µF capacitors across the
speaker maintain a low impedance at the load as fre-
quency increases.

Figure 6. Input Protection Circuit
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 capaci-
tance, 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).
TIME (5µs/div)
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:

The MAX4165–MAX4169 ha ve a hig h tole ra nc e 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 capaci-
tive-load-driving circuit in the unity-gain configuration.
The resistor improves the circuit’s phase margin by iso-
lating the load capacitor from the op amp’s output.

The MAX4165–MAX4169 can operate from a single
+ 2.7V to + 6.5V s up p ly, or from d ua l ± 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 capac-
itance 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.

two amplifiers shut down independently. Figures 12
