General DescriptionThe 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.

Applications InformationRail-to-Rail Inputs and OutputsThe
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-to-rail). 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 cross-over
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 StabilityThese 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 PumpAn internal charge pump provides two
internal supplies typically 2V beyond each rail. These internal
rails allow the MAX4162/MAX4163/MAX4164 to achieve true
rail-to-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:

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 LayoutThe 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 ConsiderationFor general UCSP package information
and PC layout considerations, please refer to the Maxim Application
Note (Wafer-Level Ultra-Chip-Board-Scale-Package).
UCSP ReliabilityThe 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.
