General Description
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 cur-
rent, low-operating voltage, and rail-to-rail output capa-
bilities make these operational amplifiers ideal for use
in single lithium ion (Li+), or two-cell NiCd or alkaline
battery systems.
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
100kΩload, 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 WLP, SC70, SOT23, µMAX®, and TSSOP packages.

Applications Information
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 VDD pin.
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.
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.
Stability
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 1. Select the smallest capacitor value that
ensures stability.
