UCSP, Micropower, Single-Supply, 10V,
Rail-to-Rail I/O Op Amps
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 commonmode 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 8pin ultra chip-scale package (UCSP™) and an 8-pin
µMAX® or SO package. The MAX4164 is available in a 14pin 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
10
suffer from midswing common-mode-rejection degradation or crossover nonlinearity often encountered in other
rail-to-rail 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 railto-rail inputs and outputs, while providing excellent
common-mode 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:
______________________________________________________________________________________
UCSP, Micropower, Single-Supply, 10V,
Rail-to-Rail I/O Op Amps
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.maxim-ic.com.

MAX4162/MAX4163/MAX4164
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.
