INA114
DESCRIPTION
The INA114 is a low cost, general purpose instrumen-
tation amplifier offering excellent accuracy. Its versa-
tile 3-op amp design and small size make it ideal for a
wide range of applications.
A single external resistor sets any gain from 1 to 10,000.
Internal input protection can withstand up to
40V
without damage.
The INA114 is laser trimmed for very low offset voltage
(50
V), drift (0.25
V/
C) and high common-mode
rejection (115dB at G = 1000). It operates with power
supplies as low as
2.25V, allowing use in battery
operated and single 5V supply systems. Quiescent cur-
rent is 3mA maximum.
The INA114 is available in 8-pin plastic and SOL-16
surface-mount packages. Both are specified for the
40
C to +85
C temperature range.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate 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
Figure 1 shows the basic connections required for operation
of the INA114. 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 resis-
tance of 5
in series with the Ref pin will cause a typical
device to degrade to approximately 80dB CMR (G = 1).
SETTING THE GAIN
Gain of the INA114 is set by connecting a single external
resistor, R
G
:
Commonly used gains and resistor values are shown in
Figure 1.
The 50k
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 val-

ues. The accuracy and temperature coefficient of these
resistors are included in the gain accuracy and drift specifi-
cations of the INA114.
The stability and temperature drift of the external gain
setting resistor, R
G
, also affects gain. R
G
'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 (possi-
bly an unstable gain error) in gains of approximately 100 or
greater.
NOISE PERFORMANCE
The INA114 provides very low noise in most applications.
For differential source impedances less than 1k
, the INA103
may provide lower noise. For source impedances greater
than 50k
, the INA111 FET-input instrumentation ampli-
fier may provide lower noise.
Low frequency noise of the INA114 is approximately
0.4
Vp-p measured from 0.1 to 10Hz. This is approximately
one-tenth the noise of "low noise" chopper-stabilized ampli-
fiers.

OFFSET TRIMMING
The INA114 is laser trimmed for very low offset voltage and
drift. Most applications require no external offset adjust-
ment. 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. This is
achieved by buffering trim voltage with an op amp as
shown.
FIGURE 2. Optional Trimming of Output Offset Voltage.
INPUT BIAS CURRENT RETURN PATH
The input impedance of the INA114 is extremely high--
approximately 10
10
. However, a path must be provided for
the input bias current of both inputs. This input bias current
is typically less than
1nA (it can be either polarity due to
cancellation circuitry). High input impedance means that
this input bias current changes very little with varying input
voltage.
Input circuitry must provide a path for this input bias current
if the INA114 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 INA114 and the
input amplifiers will saturate. If the differential source resis-
tance is low, bias current return path can be connected to one
input (see 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 common-mode rejection.
INPUT COMMON-MODE RANGE
The linear common-mode range of the input op amps of the
INA114 is approximately
13.75V (or 1.25V 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, A
1
and A
2
. The common-
mode range is related to the output voltage of the complete
amplifier--see performance curve "Input Common-Mode
Range vs Output Voltage."
A combination of common-mode and differential input
signals can cause the output of A
1
or A
2
to saturate. Figure
4 shows the output voltage swing of A
1
and A
2
expressed in
terms of a common-mode and differential input voltages.
Output swing capability of these internal amplifiers is the
same as the output amplifier, A
3
. For applications where
input common-mode range must be maximized, limit the
output voltage swing by connecting the INA114 in a lower
gain (see performance curve "Input Common-Mode Voltage
Range vs Output Voltage"). If necessary, add gain after the
INA114 to increase the voltage swing.
Input-overload often produces an output voltage that appears
normal. For example, an input voltage of +20V on one input
and +40V on the other input will obviously exceed the linear
common-mode range of both input amplifiers. Since both
input amplifiers are saturated to nearly the same output
voltage limit, the difference voltage measured by the output
amplifier will be near zero. The output of the INA114 will
be near 0V even though both inputs are overloaded.
INPUT PROTECTION
The inputs of the INA114 are individually protected for
voltages up to
40V. For example, a condition of 40V on
one input and +40V on the other input will not cause
damage. Internal circuitry on each input provides low series
impedance under normal signal conditions. To provide
equivalent protection, series input resistors would contribute
excessive noise. If the input is overloaded, the protection
circuitry limits the input current to a safe value (approxi-
mately 1.5mA). The typical performance curve "Input Bias
Current vs Common-Mode Input Voltage" shows this input

current limit behavior. The inputs are protected even if no
power supply voltage is present.
OUTPUT VOLTAGE SENSE (SOL-16 package only)
The surface-mount version of the INA114 has a separate
output sense feedback connection (pin 12). Pin 12 must be
connected to the output terminal (pin 11) for proper opera-
tion. (This connection is made internally on the DIP version
of the INA114.)
The output sense connection can be used to sense the output
voltage directly at the load for best accuracy. Figure 5 shows
how to drive a load through series interconnection resis-
tance. Remotely located feedback paths may cause instabil-
ity. This can be generally be eliminated with a high
frequency feedback path through C
1
. Heavy loads or long
lines can be driven by connecting a buffer inside the feed-
back path (Figure 6).
