LOW COST AUTOMOTIVE
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.

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 common-
mode 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.
