APPLICATIONS

GENERAL DESCRIPTION

The ALD1722E/ALD1722 is a monolithic rail-to-rail precision CMOS

operational amplifier with integrated user programmable EPAD (Electri-

callyProgrammableAnalogDevice)basedoffsetvoltageadjustment. The

ALD1722E/ALD1722 is a direct replacement of the ALD1702 operational

amplifier, with the added feature of 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 of offset voltage bias characteristics with

the aid of a personal computer under software control. Once pro-
