The INA2132 is a dual low power, unity-gain differ-
ence amplifier offering excellent value at very low
cost. Each channel consists of a precision op amp with
a laser-trimmed precision resistor network, providing
accurate gain and high common-mode rejection. Ex-
cellent TCR tracking of the resistors maintains gain
accuracy and common-mode rejection over tempera-
ture. The internal op amp鈥檚 common-mode range
extends to the negative supply鈥攊deal for single-sup-
ply applications.
The difference amplifier is the foundation of many
commonly used circuits. The INA2132 provides this
circuit function without using an expensive precision
resistor network. The INA2132 is available in the
SO-14 surface-mount package and is specified for
operation over the extended industrial temperature
range, 鈥?0擄C to +85擄C.
A single version of this product with similar specifi-
cations is also available. See the INA132 data sheet
for details.
