MAX4162/MAX4163/
MAX4164
UCSP, Micropower, Single-Supply, 10V,
Rail-to-Rail I/O Op Amps
General Description
The MAX4162/MAX4163/MAX4164 are single/dual/quad,
micropower operational amplifiers that combine an exceptional
bandwidth to power consumption ratio with true rail-to-rail
inputs and outputs. They consume a mere 25μA quiescent
current per amplifier, yet achieve 200kHz gain-bandwidth
product and are unity-gain stable while driving any capacitive
load. The MAX4162/MAX4163/MAX4164 operate from
either a single supply (2.5V to 10V) or dual supplies
(±1.25V to ±5V), with an input common-mode voltage
range that extends 250mV beyond either supply rail. These
amplifiers use a proprietary architecture to achieve a very
high input common-mode rejection ratio without the
midswing nonlinearities present in other rail-to-rail op
amps. This architecture also maintains high open-loop gain
and output swing while driving substantial loads.
The combination of excellent bandwidth/power performance,
single-supply operation, and miniature footprint makes these
op amps ideal for portable equipment and other low-power,
single-supply applications. The single MAX4162 is available
in 8-pin SO and space-saving 5-pin SOT23 packages. The
MAX4163 is available in an 8-pin ultra chip-scale
package (UCSP™) and an 8-pin μMAX® or SO package.
The MAX4164 is available in a 14-pin SO 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.

Applications Information
Rail-to-Rail Inputs and Outputs
The MAX4162/MAX4163/MAX4164 input common-mode
range extends 250mV beyond each of the supply rails,
providing a substantial increase in dynamic range over
other op amps (even many of those referred to as rail-torail). Although the minimum operating voltage is specified at
2.5V, the devices typically provide full rail-to-rail operation
below 2.0V (Figure 1). These amplifiers do not suffer from
midswing common-mode-rejection degradation or crossover nonlinearity often encountered in other rail-to-rail
www.maximintegrated.com
op amps. Extremely low, 1.0pA input bias current makes
these devices ideal for applications such as pH probes,
electrometers, and ionization detectors. They are also
protected against phase reversal (inferred from CMRR
test) and latchup for input signals extending beyond the
supply rails. The output stage achieves a lower output
impedance than traditional rail-to-rail output stages,
providing an output voltage range that typically swings
within 150mV of the supply rails for 1mA loads. This
architecture also maintains high open-loop gain and
output swing while driving substantial loads.
Output Loading and Stability
These devices drive 1mA loads to within 150mV of the
supply rails while consuming only 25μA of quiescent
current. Internal compensation allows these amplifiers to
remain unity-gain stable while driving any capacitive load
(Figure 2).
Internal Charge Pump
An internal charge pump provides two internal supplies
typically 2V beyond each rail. These internal rails allow
the MAX4162/MAX4163/MAX4164 to achieve true rail-torail inputs and outputs, while providing excellent commonmode rejection, power-supply rejection ratios, and gain
linearity.
These charge pumps require no external components,
and in most applications are entirely transparent to the
user. Two characteristics may be visible to the user,
depending on the application:
Maxim Integrated │ 10
MAX4162/MAX4163/
MAX4164
UCSP, Micropower, Single-Supply, 10V,
Rail-to-Rail I/O Op Amps
1) The on-board charge pumps generate a small
amount of 700kHz switching noise at the op amp’s
output. The amplitude of this noise is typically
100μVP-P. The noise is not referred to the input, and
is independent of amplifier gain. The charge-pump
switching frequency is well beyond the amplifier’s
200kHz bandwidth, and is therefore unnoticeable in
most applications.
2) The charge pumps typically require up to 20μs on
power-up to fully energize the internal supply rails
(Figure 3).
Power Supplies and Layout
The MAX4162/MAX4163/MAX4164 are guaranteed to
operate from a single 2.5V to 10.0V power supply, but
full rail-to-rail operation typically extends below 2V. For
single-supply operation, bypass the power supply with a
1μF capacitor in parallel with a 0.1μF ceramic capacitor.
If operating from dual supplies, bypass each supply to
ground.
Good layout improves performance by decreasing the
amount of stray capacitance at the op amp’s inputs and
output. To decrease stray capacitance, minimize both
trace and external component lead lengths, and place
external components close to the op amp’s pins.
UCSP Package Consideration
For general UCSP package information and PC layout
considerations, please refer to the Maxim Application
Note (Wafer-Level Ultra-Chip-Board-Scale-Package).
UCSP Reliability
The UCSP represents a unique packaging form factor
that may not perform equally to a packaged product
through traditional mechanical reliability tests. UCSP
reliability is integrally linked to the user’s assembly
methods, circuit board material, and usage environment.
The user should closely review these areas when considering
use of a UCSP. Performance through operating life test
and moisture resistance remains uncompromised as it
is primarily determined by the wafer-fabrication process.
Mechanical stress performance is a greater consideration
for a UCSP package. UCSPs are attached through direct
solder contact to the user’s PC board, foregoing the inherent
stress relief of a packaged product lead frame. Solder
joint contact integrity must be considered.
Table 1 shows the testing done to characterize the UCSP
reliability performance. In conclusion, the UCSP is capable
of performing reliably through environmental stresses as
indicated by the results in the table. Additional usage data
and recommendations are detailed in the UCSP application
note, which can be found on Maxim’s website at www.
maximintegrated.com.
