Description:

The devices are general-purpose, fixed-gain differenceamplifiers,which are intended for precision signalconditioning. The devices have extremely low-gain driftwithin the operating temperature range. The devices alsoprovide an exceptional common-mode rejection ratio (85dB typical). The common-mode range of the amplifiersexceeds the supply voltage rails, making the devices idealfor single-supply applications that require a wide commonmode voltage range.
