The INA143 and INA2143 are high slew rate, gain of 10V/V or 0.1V/V difference amplifiers 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 commonmode rejection over temperature. They operate over a wide supply range, ±2.25V to ±18V (+4.5V 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 low cost INA143 and INA2143 provide this precision circuit function without using an expensive precision network.

The single version, INA143, package is the SO-8 surface mount. The dual version, INA2143, package is the SO-14 surface mount. Both are specified for operation over the extended industrial temperature range, 40 to +85. Operation is from 55 to +125.
