в—Џ G = 2 AMPLIFIER DESCRIPTION V+ The INA132 is a low power, unity-gain differential
amplifier consisting of a precision op amp with a
precision resistor network. The on-chip resistors are
laser trimmed for accurate gain and high commonmode rejection. Excellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over temperature. The internal op amp’s common-mode range extends to the negative supply—
ideal for single-supply applications. It operates on
single (2.7V to 36V) or dual supplies (В±1.35V to
В±18V).
The differential amplifier is the foundation of many …
