ALD1721E - Advanced Linear Devices

ALD1721E EPAD MICROPOWER OPERATIONAL AMPLIFIER

The ALD1721E is a monolithic rail-to-rail precision CMOS operational amplifier with integrated user programmable EPAD (Electrically Programmable Analog Device) based offset voltage adjustment. The ALD1721E operational amplifier is a direct replacement of the ALD1701 operational amplifier, with the added feature of user-programmable offset voltage trimming re.
