INA143U .

The INA143U is a high-speed precision Difference Amplifier consisting of a precision op amp with a precision resistor network. The on-chip resistors are laser trimmed for accurate gain and high common-mode rejection. Excellent TCR tracking of the resistor maintains gain accuracy and common-mode rejection over temperature. It operates over a wide supply range, ±2.25 to ±18V (+4.5 to +36V single supply) and input common-mode voltage range extends beyond the positive and negative supply rails. The differential amplifier is the foundation of many commonly used circuits. The INA143 provide this precision circuit function without using an expensive precision network.
