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
commonly 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.

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 peak­to-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 integral 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
published specifications.
