Texas Instruments INA105
The INA105 is a monolithic Gain = 1 differential amplifier consisting of a precision operational amplifier (op amp) and on-chip metal film resistor network. The resistors are laser trimmed for accurate gain and high common-mode rejection. The input common-mode range extends beyond the positive and negative supply rails.| Part No. | INA105 |

DESCRIPTION
Excellent tracking of resistors (TCR) maintains gain accuracy and common-mode rejection over temperature. The differential amplifier is the foundation of many commonly used circuits. The INA105 provides precision circuit function without using an expensive precision resistor network. The INA105 is available in 8-pin plastic DIP, SOIC surface-mount and TO-99 metal packages.
