TEB1033

® TEB1033 TEF1033-TEC1033 PRECISION DUAL OPERATIONAL AMPLIFIERS . . . . . . . . . . VERY LOW INPUT OFFSET VOLTAGE : 1mV max. LOW DISTORTION RATIO LOW NOISE VERY LOW SUPPLY CURRENT LOW INPUT OFFSET CURRENT LARGE COMMON-MODE RANGE HIGH OUTPUT CURRENT GAIN-BANDWIDTH PRODUCT : 2MHz TEMPERATURE DRIFT : 2µV/oC LONG TERM STABILITY : 8µV/YEAR (for Tamb ≤ 50oC) N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) DESCRIPTION The TEB1033, TEF1033 and TEC1033 are high performance dual-operational amplifiers intended for active filter applications. The internal phase compensation allows stable operation as voltage follower in spite of their high gain-bandwidth product. The circuits present very stable electrical characteristics over the entire supply voltage range.
