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 common-mode rejection. Excellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over temperature. The internal op amp common-mode range extends to the negative supply—an excellent choice for single-supply applications. The INA132 operates on single (2.7V to 36V) or dual (±1.35V to ±18V) supplies. The differential amplifier is the foundation of many commonly used circuits. The INA132 provides this circuit function without using an expensive precision resistor network. The INA132 is available in an SO-8 surface-mount package and operates over the industrial temperature range of –40°C to +85°C.
