DESCRIPTION

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°C to +85°C.

Operation is from –55°C to +125°C.
