1 TEB TEF-TEC PRECISION DUAL OPERATIONAL AMPLIFIERS. ERY LOW INPUT OFFSET OLTAGE : 1m max. LOW DISTORTION RATIO LOW NOISE ERY LOW SUPPLY CURRENT LOW INPUT OFFSET CURRENT LARGE COMMON-MODE RANGE HIGH OUTPUT CURRENT. GAIN-BANDWIDTH PRODUCT : 2MHz TEMPERATURE DRIFT : 2µ/ o C LONG TERM STABILITY : 8µ/YEAR (for Tamb 50 o C) N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) DESCRIPTION The TEB, TEF and TEC 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.
