High Speed FET-Input
INSTRUMENTATION AMPLIFIER
FEATURES
DESCRIPTION
● FET INPUT: IB = 20pA max
The INA111 is a high speed, FET-input instrumentation amplifier offering excellent performance.
● LOW OFFSET VOLTAGE: 500µV max
● LOW OFFSET VOLTAGE DRIFT:
5µV/°C max
The INA111 uses a current-feedback topology providing extended bandwidth (2MHz at G = 10) and fast
settling time (4µs to 0.01% at G = 100). A single
external resistor sets any gain from 1 to over 1000.
● HIGH SPEED: TS = 4µs (G = 100, 0.01%)
● HIGH COMMON-MODE REJECTION:
106dB min
Offset voltage and drift are laser trimmed for excellent
DC accuracy. The INA111’s FET inputs reduce input
bias current to under 20pA, simplifying input filtering
and limiting circuitry.
● 8-PIN PLASTIC DIP, SOL-16 SOIC
The INA111 is available in 8-pin plastic DIP, and
SOL-16 surface-mount packages, specified for the
–40°C to +85°C temperature range.

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

APPLICATION INFORMATION
The 50kΩ term in equation 1 comes from the sum of the two
internal feedback resistors. These are on-chip metal film
resistors which are laser trimmed to accurate absolute values. The accuracy and temperature coefficient of these
resistors are included in the gain accuracy and drift specifications of the INA111.
Figure 1 shows the basic connections required for operation
of the INA111. Applications with noisy or high impedance
power supplies may require decoupling capacitors close to
the device pins as shown.
The output is referred to the output reference (Ref) terminal
which is normally grounded. This must be a low-impedance
connection to assure good common-mode rejection. A resistance of 2Ω in series with the Ref pin will cause a typical
device with 90dB CMR to degrade to approximately 80dB
CMR (G = 1).
The stability and temperature drift of the external gain
setting resistor, RG, also affects gain. RG’s contribution to
gain accuracy and drift can be directly inferred from the gain
equation (1). Low resistor values required for high gain can
make wiring resistance important. Sockets add to the wiring
resistance, which will contribute additional gain error (possibly an unstable gain error) in gains of approximately 100
or greater.
SETTING THE GAIN
Gain of the INA111 is set by connecting a single external
resistor, RG:
G = 1 + 5 0kΩ
RG
DYNAMIC PERFORMANCE
The typical performance curve “Gain vs Frequency” shows
that the INA111 achieves wide bandwidth over a wide range
of gain. This is due to the current-feedback topology of the
INA111. Settling time also remains excellent over wide
gains.

Commonly used gains and resistor values are shown in

INA111
INPUT BIAS CURRENT RETURN PATH
The INA111 exhibits approximately 6dB rise in gain at
2MHz in unity gain. This is a result of its current-feedback
topology and is not an indication of instability. Unlike an op
amp with poor phase margin, the rise in response is a
predictable +6dB/octave due to a response zero. A simple
pole at 700kHz or lower will produce a flat passband
response (see Input Filtering).
The input impedance of the INA111 is extremely high—
approximately 1012Ω. However, a path must be provided for
the input bias current of both inputs. This input bias current
is typically less than 10pA. High input impedance means
that this input bias current changes very little with varying
input voltage.
The INA111 provides excellent rejection of high frequency
common-mode signals. The typical performance curve,
“Common-Mode Rejection vs Frequency” shows this behavior. If the inputs are not properly balanced, however,
common-mode signals can be converted to differential sig–
+
nals. Run the VIN and VIN connections directly adjacent each
other, from the source signal all the way to the input pins. If
possible use a ground plane under both input traces. Avoid
running other potentially noisy lines near the inputs.
Input circuitry must provide a path for this input bias current
if the INA111 is to operate properly. Figure 3 shows various
provisions for an input bias current path. Without a bias
current return path, the inputs will float to a potential which
exceeds the common-mode range of the INA111 and the
input amplifiers will saturate.
If the differential source resistance is low, the bias current
return path can be connected to one input (see the thermocouple example in Figure 3). With higher source impedance,
using two resistors provides a balanced input with possible
advantages of lower input offset voltage due to bias current
and better high-frequency common-mode rejection.
NOISE AND ACCURACY PERFORMANCE
The INA111’s FET input circuitry provides low input bias
current and high speed. It achieves lower noise and higher
accuracy with high impedance sources. With source impedances of 2kΩ to 50kΩ the INA114 may provide lower offset
voltage and drift. For very low source impedance (≤1kΩ),
the INA103 may provide improved accuracy and lower
noise.

OFFSET TRIMMING
INA111
1MΩ
The INA111 is laser trimmed for low offset voltage and
drift. Most applications require no external offset adjustment. Figure 2 shows an optional circuit for trimming the
output offset voltage. The voltage applied to Ref terminal is
summed at the output. Low impedance must be maintained
at this node to assure good common-mode rejection. The op
amp shown maintains low output impedance at high frequency. Trim circuits with higher source impedance should
be buffered with an op amp follower circuit to assure low
impedance on the Ref pin.

INPUT COMMON-MODE RANGE
100Ω(1)
The linear common-mode range of the input op amps of the
INA111 is approximately ±12V (or 3V from the power
supplies). As the output voltage increases, however, the
linear input range will be limited by the output voltage swing
of the input amplifiers, A1 and A2. The common-mode range
is related to the output voltage of the complete amplifier—
see performance curve “Input Common-Mode Range vs
Output Voltage”.

the 1N4148 may have leakage currents far greater than the
input bias current of the INA111 and are usually sensitive to
light.
A combination of common-mode and differential input
voltage can cause the output of A1 or A2 to saturate. Figure
4 shows the output voltage swing of A1 and A2 expressed in
terms of a common-mode and differential input voltages.
For applications where input common-mode range must be
maximized, limit the output voltage swing by connecting the
INA111 in a lower gain (see performance curve “Input
Common-Mode Voltage Range vs Output Voltage”). If
necessary, add gain after the INA111 to increase the voltage
swing.
INPUT FILTERING
The INA111’s FET input allows use of an R/C input filter
without creating large offsets due to input bias current.
Figure 6 shows proper implementation of this input filter to
preserve the INA111’s excellent high frequency commonmode rejection. Mismatch of the common-mode input capacitance (C1 and C2), either from stray capacitance or
Input-overload often produces an output voltage that appears
normal. For example, consider an input voltage of +14V on
one input and +15V on the other input will obviously exceed
the linear common-mode range of both input amplifiers.
Since both input amplifiers are saturated to the nearly the
same output voltage limit, the difference voltage measured
by the output amplifier will be near zero. The output of the
INA111 will be near 0V even though both inputs are
overloaded.

INPUT PROTECTION
Inputs of the INA111 are protected for input voltages from
0.7V below the negative supply to 15V above the positive
power supply voltages. If the input current is limited to less
than 1mA, clamp diodes are not required; internal junctions
will clamp the input voltage to safe levels. If the input source
can supply more than 1mA, use external clamp diodes as
shown in Figure 5. The source current can be limited with
series resistors R1 and R2 as shown. Resistor values greater
than 10kΩ will contribute noise to the circuit.

mismatched values, causes a high frequency common-mode
signal to be converted to a differential signal. This degrades
common-mode rejection. The differential input capacitor,
C3, reduces the bandwidth and mitigates the effects of
mismatch in C1 and C2. Make C3 much larger than C1 and
C2. If properly matched, C1 and C2 also improve CMR.

The surface-mount version of the INA111 has a separate
output sense feedback connection (pin 12). Pin 12 must be
connected, usually to the output terminal, pin 11, for proper
operation. (This connection is made internally on the DIP
version of the INA111.)

FIGURE 8. Remote Load and Ground Sensing.
The output feedback connection can be used to sense the
output voltage directly at the load for best accuracy. Figure 8
shows how to drive a load through series interconnection
resistance. Remotely located feedback paths may cause
instability. This can be generally be eliminated with a high
frequency feedback path through C1.
