MAX44294
36V, Single/Dual/Quad, Low-Noise Amplifiers
with Maximum 0.5µV/°C Offset Drift
General Description
Benefits and Features
● Low Input Noise and High Bandwidth to Drive
The MAX44291/MAX44292/MAX44294 are single/dual/
quad low-noise, precision operational amplifiers. The low
offset and low noise specifications and high supply range
make the MAX44291/MAX44292/MAX44294 ideal for
sensor interfaces, loop-powered systems, and various
types of medical and data acquisition instruments.
Precision ADCs
•
•
4.9nV/√Hz Low Input Noise
10MHz Gain-Bandwidth Product
● Low Input Offset Ensures Accurate Results Over
Temperature
The MAX44291/MAX44292/MAX44294 operate with a
wide supply voltage range from a 4.5V to 36V single
supply or dual ±2.25V to ±18V supplies, and consume
only 1.2mA/channel (typ). The MAX44291 features a
shutdown input that reduces the supply current to 1μA/
channel (typ) when in shutdown mode.
•
•
125µV (max) Low Input Offset Voltage
0.5µV/°C (max) Offset Drift
● Low 1.2mA Quiescent Current (Per Channel) Does
Not Break the Power Budget
● ESD Protection Provides Robust Front-End
• ±8kV Human Body Model
The rail-to-rail output swing maximizes the dynamic range
when driving high-resolution ADCs even with low supply
voltage. These devices achieve 10MHz of gain-bandwidth
product.
• ±1kV Charged Device Model
● Wide Supply for High-Voltage Front-Ends
•
Single 4.5V to 36V or Dual ±2.25V to ±18V Supply
Ranges
The MAX44291/MAX44292/MAX44294 are available in
8-pin μMAX® (single), 8-pin SO (dual), and 14-pin SO
(quad) packages and are specified over the -40°C to
+125°C automotive temperature range.
● 8-Pin µMAX and 8-/14-Pin SO Packages Save Board
Space
Applications
● Portable Logic Controllers
● Instrumentation
● Test and Measurement Systems
● Sensor Interfaces

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 MAX44291/MAX44292/MAX44294 are unity-gain
stable and operate either with single-supply voltage from
4.5V to 36V or with dual supplies from ±2.25V to ±18V.
Applications Information
High Operating Supply Voltage Range
Figure 1. Showing Input Differential Protection Scheme
The MAX44291/MAX44292/MAX44294 operate with a
wide voltage range from single supply +4.5V to +36V or
dual supplies from ±2.25V to ±18V. These devices con-
sume only 1.2mA (typical) of supply current per channel.
Although the MAX44291/MAX44292/MAX44294 support
high-voltage operation with excellent performance, the
devices also operate in many battery-operated or portable
equipment applications at 5V.
Shutdown (MAX44291 Only)
The MAX44291 shutdown input is referenced to the posi-
tive supply. See the Electrical Characteristics table for the
proper levels of functionality. A high level (above V
0.35V) disables the op amp and puts the output into high-
impedance state. A low level (below V - 3V) enables
the device. As an example, if the op amp is powered with
dual supplies of ±15V, the device is enabled when the
shutdown voltage is at or below 12V. The device is dis-
abled when the shutdown voltage is at or above 14.65V. If
the op amp is powered with 36V single supply, the device
is enabled when the shutdown voltage is at or below 33V.
The device is disabled when the shutdown voltage is at
or above 35.65V. This input must be connected to either
a valid high or low voltage. Do not leave it unconnected.

Input Protection
The MAX44291/MAX44292/MAX44294 have a typical
ESD protection scheme with diodes from input, output,
and shutdown pins to either rails. Also, as shown in Figure
1, the protection scheme shows diodes and a resistor
string between the inputs to protect the IC from large
differential inputs. Input series resistors act as current-
limiting resistors when a large differential voltage is acci-
dentally applied.
When in shutdown mode, the amplifier consumes only
1.8µA (typical) of supply current.
Rail-to-Rail Output Stage
Power Supplies and Layout
The MAX44291/MAX44292/MAX44294 output stage
swings to within 100mV (typ) of either power-supply
rail with a 10kΩ load to ground and provides a 10MHz
GBW with a 5V/µs slew rate. The devices are unity-gain
stable, and can drive a 100pF capacitive load without
compromising stability. Stability with higher capacitive
loads can be improved by adding an isolation resistor in
series with the op-amp output. This resistor improves the
circuit’s phase margin by isolating the load capacitor from
the amplifier’s output. The graph in the Typical Operating
Characteristics shows a profile of the isolation resistor
and capacitive load values that maintain the devices in
the stable region.
The MAX44291/MAX44292/MAX44294 operate with dual
supplies from ±2.25V to ±18V or with a single supply
from +4.5V to +36V with respect to ground. When used
with dual supplies, bypass both V
and V

and 10µF capacitor

to ground closer to where the power supply connection
is made. When used with a single supply, bypass V
DD
with a 0.1µF and 10µF capacitors to ground as explained
above. Careful layout technique helps optimize perfor-
mance by decreasing the amount of stray capacitance
at the amplifier inputs and outputs. To decrease stray
capacitance, minimize trace lengths by placing external
components close to the amplifier pins.

Electrostatic Discharge (ESD)
The MAX44291/MAX44292/MAX44294 have built-in cir-
cuits to protect from electrostatic discharge (ESD) events.
An ESD event produces a short, high-voltage pulse that is
transformed into a short current pulse once it discharges
through the device. The built-in protection circuit provides
a current path around the op amp that prevents it from
being damaged. The energy absorbed by the protection
circuit is dissipated as heat.
Not all ESD events involve the transfer of charge into the
device. Electrostatic discharge from a charged device to
another conductive body at lower potential is also a form
of ESD. Such an ESD event is known as Charged Device
Model (CDM) ESD, which can be even more destruc-
tive than HBM ESD (despite its shorter pulse duration)
because of its high current. The MAX44291/MAX44292/
MAX44294 guarantee CDM ESD protection up to 1kV.
The MAX44291/MAX44292/MAX44294 guarantee ESD
protection up to 8kV with Human Body Model (HBM).
The Human Body Model simulates the ESD phenomenon
wherein a charged body directly transfers its accumu-
lated electrostatic charge to the ESD-sensitive device. A
common example of this phenomenon is when a person
accumulates static charge by walking across a carpet and
