The INA133 and INA2133 are high slew rate, unity-gain difference amplifiers consisting of a precision opamp with a precision resistor network. The on-chipresistors are laser trimmed for accurate gain and highcommon-mode rejection. Excellent TCR tracking of theresistors maintains gain accuracy and common-moderejection over temperature. They operate over a widesupply range, ±2.25V to ±18V (+4.5V to +36V singlesupply), and input common-mode voltage range extendsbeyond the positive and negative supply rails.The differential amplifier is the foundation of manycommonly used circuits. The low cost INA133 andINA2133 provide this precision circuit function withoutusing an expensive precision network.The single version, INA133, package is the SO-8 surfacemount. The dual version, INA2133, package is the SO-14surface mount. Both are specified for operation over theextended industrial temperature range, –40°C to +85°C.Operation is from –55°C to +125°C.
