Single/Dual/Quad, +1.8V/750nA, SC70,
Rail-to-Rail Op Amps
General Description
Features
The MAX4464/MAX4470/MAX4471/MAX4472/MAX4474
family of micropower op amps operate from a single
+1.8V to +5.5V supply and draw only 750nA of supply
current. The MAX4470 family feature ground-sensing
inputs and Rail-to-Rail® output. The ultra-low supply
current, low-operating voltage, and rail-to-rail output
capabilities make these operational amplifiers ideal for
use in single lithium ion (Li+), or two-cell NiCd or alka-
line battery systems.
ꢀ Ultra-Low 750nA Supply Current Per Amplifier
ꢀ Ultra-Low +1.8V Supply Voltage Operation
ꢀ Ground-Sensing Input Common-Mode Range
ꢀ Outputs Swing Rail-to-Rail
ꢀ Outputs Source and Sink 11mA of Load Current
ꢀ No Phase Reversal for Overdriven Inputs
ꢀ High 120dB Open-Loop Voltage Gain
ꢀ Low 500µV Input Offset Voltage
The rail-to-rail output stage of the MAX4464/MAX4470/
MAX4471/MAX4472/MAX4474 amplifiers is capable of
driving the output voltage to within 4mV of the rail with a
100kΩ load, and can sink and source 11mA with a +5V
supply. These amplifiers are available in both fully com-
pensated and decompensated versions. The single
MAX4470, dual MAX4471, and the quad MAX4472 are
unity-gain stable. The single MAX4464 and the dual
MAX4474 are stable for closed-loop gain configurations
of ≥ +5V/V. These amplifiers are available in space-sav-
ing SC70, SOT23, µMAX, and TSSOP packages.

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.

Stability
Applications Information
The MAX4464/MAX4470/MAX4471/MAX4472/MAX4474
maintain stability in their minimum gain configuration
while driving capacitive loads. Although this product
family is primarily designed for low-frequency applica-
tions, good layout is extremely important because low-
power requirements demand high-impedance circuits.
The layout should also minimize stray capacitance at the
amplifier inputs. However some stray capacitance may
be unavoidable, and it may be necessary to add a 2pF
to 10pF capacitor across the feedback resistor as shown
in Figure 2. Select the smallest capacitor value that
ensures stability.
Ground Sensing
The common-mode input range of the MAX4470 family
extends down to ground, and offers excellent common-
mode rejection. These devices are guaranteed not to
undergo phase reversal when the input is overdriven.
Power Supplies and Layout
The MAX4470 family operates from a single +1.8V to
+5.5V power supply. Bypass power supplies with a
0.1µF ceramic capacitor placed close to the V
pin.
DD
Ground layout improves performance by decreasing the
amount of stray capacitance and noise at the op amp’s
inputs and outputs. To decrease stray capacitance, mini-
mize PC board lengths and resistor leads, and place
external components close to the op amps’ pins.

IN
Bandwidth
The MAX4470/MAX4471/MAX4472 are internally
compensated for unity-gain stability and have a typical
gain-bandwidth of 9kHz. The MAX4464/MAX4474 have
a 40kHz typical gain-bandwidth and are stable for a
gain of +5V/V or greater.
