DESCRIPTION
The INA103 is a very low noise, low distortion mono-
lithic instrumentation amplifier. Its current-feedback
circuitry achieves very wide bandwidth and excellent
dynamic response. It is ideal for low-level audio
signals such as balanced low-impedance microphones.
The INA103 provides near-theoretical limit noise per-
formance for 200source impedances. Many indus-
trial applications also benefit from its low noise and
wide bandwidth.
Unique distortion cancellation circuitry reduces dis-
tortion to extremely low levels, even in high gain. Its
balanced input, low noise and low distortion provide
superior performance compared to transformer-coupled
microphone amplifiers used in professional audio
equipment.
The INA103’s wide supply voltage (±9 to ±25V) and
high output current drive allow its use in high-level
audio stages as well. A copper lead frame in the plastic
DIP assures excellent thermal performance.
The INA103 is available in 16-pin plastic DIP and
SOL-16 surface-mount packages. Commercial and In-
dustrial temperature range models are available.

NOTES: (1) Gains other than 1 and 100 can be set by adding an external resistor, RG between pins 2 and 15. Gain accuracy is a function of RG. (2) FS = Full Scale.
(3) Adjustable to zero. (4) VO = 0V, see Typical Curves for VCM vs VO. (5) VNOISE RTI = V2N INPUT + (VN OUTPUT/Gain)2 + 4KTRG. See Typical Curves. (6) Time required
for output to return from saturation to linear operation following the removal of an input overdrive voltage.

ELECTROSTATIC
DISCHARGE SENSITIVITY
Any 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 degrada-
tion 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
published specifications.
