DESCRIPTION
The INA106 is a monolithic Gain = 10 differential amplifier
consisting of a precision op amp and on-chip metal film
resistors. The resistors are laser trimmed for accurate gain
and high common-mode rejection. Excellent TCR tracking
of the resistors maintains gain accuracy and common-mode
rejection over temperature.
The differential amplifier is the foundation of many com-
monly used circuits. The INA106 provides this precision
circuit function without using an expensive resistor network.
The INA106 is available in 8-pin plastic DIP and SO-8
surface-mount packages.FEATURES

NOTES: (1) Connected as difference amplifier (see Figure 1). (2) Nonlinearity is the maximum peak deviation from the best-fit straight line as a percent of full-scale peak-
to-peak output. (3) With zero source impedance (see “Maintaining CMR” section). (4) Includes effects of amplifiers’s input bias and offset currents. (5) Includes effect
of amplifier’s input current noise and thermal noise contribution of resistor network.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments 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 its
published specifications.
