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.
