MAX9938
nanoPower, 4-Bump UCSP/SOT23,
Precision Current-Sense Amplifier
General Description
The MAX9938 high-side current-sense amplifier offers
precision accuracy specifications of VOS less than 500μV
(max) and gain error less than 0.5% (max). Quiescent
supply current is an ultra-low 1μA. The MAX9938 fits
in a tiny, 1mm x 1mm UCSP™ package size or a 5-pin
SOT23 package, making the part ideal for applications in
notebook computers, cell phones, PDAs, and all batteryoperated portable devices where accuracy, low quiescent
current, and small size are critical.
The MAX9938 features an input common-mode voltage
range from 1.6V to 28V. These current-sense amplifiers have a voltage output and are offered in four gain
versions: 25V/V (MAX9938T), 50V/V (MAX9938F),
100V/V (MAX9938H), and 200V/V (MAX9938W).
The four gain selections offer flexibility in the choice of
the external current-sense resistor. The very low 500μV
(max) input offset voltage allows small 25mV to 50mV
full-scale VSENSE voltage for very low voltage drop at
full-current measurement.

Detailed Description
same value as R1 to minimize offset voltage. The current through R1 is sourced by a high-voltage p-channel
FET. Its source current is the same as its drain current,
which flows through a second gain resistor, ROUT. This
produces an output voltage, VOUT, whose magnitude is
ILOAD x RSENSE x ROUT/R1. The gain accuracy is based
on the matching of the two gain resistors R1 and ROUT
(see Table 1). Total gain = 25V/V for the MAX9938T,
50V/V for the MAX9938F, 100V/V for the MAX9938H, and
200V/V for the MAX9938W. The output is protected from
input overdrive by use of an output current limiting circuit
of 7mA (typical) and a 6V clamp protection circuit.
The MAX9938 unidirectional high-side, current-sense
amplifier features a 1.6V to 28V input common-mode
range. This feature allows the monitoring of current out
of a battery with a voltage as low as 1.6V. The MAX9938
monitors current through a current-sense resistor and
amplifies the voltage across that resistor.
The MAX9938 is a unidirectional current-sense amplifier
that has a well-established history. An op amp is used
to force the current through an internal gain resistor at
RS+, which has a value of R1, such that its voltage drop
equals the voltage drop across an external sense resistor, RSENSE. There is an internal resistor at RS- with the

Applications Information
Choosing the Sense Resistor
Choose RSENSE based on the following criteria:
Voltage Loss
A high RSENSE value causes the power-source voltage
to drop due to IR loss. For minimal voltage loss, use the
lowest RSENSE value.
OUT Swing vs. VRS+ and VSENSE
The MAX9938 is unique since the supply voltage is the
input common-mode voltage (the average voltage at RS+
and RS-). There is no separate VCC supply voltage pin.
Therefore, the OUT voltage swing is limited by the minimum voltage at RS+.
VOUT (max) = VRS+ (min) - VSENSE (max) - VOH
and
R SENSE =
VOUT (max)
G × I LOAD (max)
VSENSE full scale should be less than VOUT/gain at the
minimum RS+ voltage. For best performance with a 3.6V
supply voltage, select RSENSE to provide approximately
120mV (gain of 25V/V), 60mV (gain of 50V/V), 30mV (gain
of 100V/V), or 15mV (gain of 200V/V) of sense voltage for
the full-scale current in each application. These can be
increased by use of a higher minimum input voltage.
Accuracy
In the linear region (VOUT < VOUT(max)), there are two
components to accuracy: input offset voltage (VOS) and
gain error (GE). For the MAX9938, VOS = 500μV (max)
and gain error is 0.5% (max). Use the linear equation:
VOUT = (gain ± GE) x VSENSE ± (gain x VOS)
to calculate total error. A high RSENSE value allows lower
currents to be measured more accurately because offsets
are less significant when the sense voltage is larger.
www.maximintegrated.com
Efficiency and Power Dissipation
At high current levels, the I2R losses in RSENSE can be
significant. Take this into consideration when choosing the
resistor value and its power dissipation (wattage) rating.
Also, the sense resistor’s value might drift if it is allowed to
heat up excessively. The precision VOS of the MAX9938
allows the use of small sense resistors to reduce power
dissipation and reduce hot spots.
Kelvin Connections
Because of the high currents that flow through RSENSE,
take care to eliminate parasitic trace resistance from
causing errors in the sense voltage. Either use a fourterminal current-sense resistor or use Kelvin (force and
sense) PCB layout techniques.
Optional Output Filter Capacitor
When designing a system that uses a sample-and-hold
stage in the ADC, the sampling capacitor momentarily
loads OUT and causes a drop in the output voltage. If
sampling time is very short (less than a microsecond),
consider using a ceramic capacitor across OUT and
GND to hold VOUT constant during sampling. This also
decreases the small-signal bandwidth of the currentsense amplifier and reduces noise at OUT.
Input Filters
Some applications of current-sense amplifiers need to
measure currents accurately even in the presence of both
differential and common-mode ripple, as well as a wide
variety of input transient conditions. For example, highfrequency ripple at the output of a switching buck or boost
regulator results in a common-mode voltage at the inputs
of the MAX9938. Alternatively, fast load-current transients, when measuring at the input of a switching buck
or boost regulator, can cause high-frequency differential
sense voltages to occur at the inputs of the MAX9938,
although the signal of interest is the average DC value.
Such high-frequency differential sense voltages may
result in a voltage offset at the MAX9938 output.

MAX9938
nanoPower, 4-Bump UCSP/SOT23,
Precision Current-Sense Amplifier
The MAX9938 allows two methods of filtering to help
improve performance in the presence of input commonmode voltage and input differential voltage transients.
Figure 1 shows a differential input filter.
Placing RIN at the RS- input does not affect the gain
error of the device because the gain is given by the ratio
between ROUT and R1 at RS+.
The capacitor CIN between RS+ and RS- along with the
resistor RIN between the sense resistor and RS- helps
filter against input differential voltages and prevents them
from reaching the MAX9938.
Again, the corner frequency of the filter is determined by
the choice of RIN, CIN and is affected by R1.
In this case RIN affects both gain error and input offset
voltage. RIN should be smaller than R1 so that it has negligible effect on the device gain. If, for example, a filter with
RIN = 10Ω and CIN = 1μF is built, then depending upon the
gain selection, the gain error is affected by either 2.5% (G =
25V/V, R1 = 400Ω) or 5% (G = 50V/V, R1 = 200Ω) or 10%
(G = 100V/V, R1 = 100Ω) or 10% (G = 200V/V, R1 = 100Ω).
The corner frequency of this filter is determined by the
choice of RIN, CIN, and the value of the input resistance
at RS- (R1). See Table 1 for R1 values at the different
gain options.
The value of RIN should be chosen to minimize its effect
on the input offset voltage due to the bias current at RS-.
RIN x IBIAS contributes to the input voltage offset. IBIAS
is typically 0.2μA.

Bidirectional Application
Battery-powered systems may require a precise bidirectional current-sense amplifier to accurately monitor the
battery’s charge and discharge currents. Measurements
of the two separate outputs with respect to GND yields an
accurate measure of the charge and discharge currents
respectively (Figure 3).
