DESCRIPTION

The INA133 and INA2133 are high slew rate, unity-

gain difference amplifiers 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. They operate over a wide

supply range,

±2.25V to ±18V (+4.5V to +36V single

supply), and 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 low cost INA133 and

INA2133 provide this precision circuit function without

using an expensive precision network.

The single version, INA133, package is the SO-8 surface

mount. The dual version, INA2133, package is the SO-14

surface mount. Both are specified for operation over the

extended industrial temperature range, –40

°C to +85°C.

Operation is from –55

°C to +125°C.
