ALD2721

ADVANCED LINEAR DEVICES, INC. ALD2721E/ALD2721 DUAL EPAD™ MICROPOWER OPERATIONAL AMPLIFIER KEY FEATURES EPAD ( Electrically Programmable Analog Device) User programmable VOS trimmer Computer-assisted trimming Rail-to-rail input/output Compatible with standard EPAD Programmer Each amplifier VOS can be trimmed to a different Vos level High precision through in-system circuit trimming www.DataSheet4U.com Reduces or eliminates VOS, PSRR, CMRR and TCVOS errors System level “calibration” capability Application Specific Programming mode In-System Programming mode Electrically programmable to compensate for external component tolerances Achieves 0.01pA input bias current and 35µV input offset voltage with micropower Low voltage operation GENERAL DESCRIPTION The ALD2721E/ALD2721 is a dual monolithic rail-to-rail precision CMOS operational amplifier with integrated user programmable EPAD (Electrically Programmable Analog Device) based offset voltage adjustment. The ALD2721E/ALD2721 is a dual version of the ALD1721E/ALD1721 operational amplifier. Each ALD2721E/ALD2721 operational amplifier features individual, user-programmable offset voltage trimming resulting in significantly enhanced total system performance and user flexibility. EPAD technology is an exclusive ALD design which has been refined for analog applications where precision voltage trimming is necessary to achieve a desired performance. It utilizes CMOS FETs as in-circuit elements for trimming...
