The INA133 and INA2133 are high slew rate, unity gain difference amplifiers made up of a precision operational amplifier with a precision resistor network. The on-chip resistors are laser trimmed for accurate gain and high common-mode rejection. Excellent tracking of resistors (TCR) maintains gain accuracy and common-mode rejection over temperature. The INAx133 operates over a wide supply range, ±2.25V to ±18V (+4.5V to +36V single supply), and that 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 INAx133 provides this precision circuit function for cost-optimized designs.

The single INA133 version is available in the SOIC-8 surface mount package. The dual INA2133 version is available in SOIC-14 package. Both are specified for operation over the industrial temperature range −40°C to +85°C.Read more
