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 INA105 provides this precision circuit function without using an expensive precision resistor network.
The INA105 is available in 8-pin plastic DIP, SO-8 surface-mount and TO-99 metal packages.
