GENERAL DESCRIPTION
The ALD2726E/ALD2726 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 ALD2726E/ALD2726 is a dual version of the ALD1726E/ALD2726 operational amplifier. Each ALD2721E/ALD2721 operational amplifier features individual user-programming 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 puter under software control. Once programmed, the set parameters are stored indefinitely within the device even after power-down. EPAD offers the circuit designer a convenient and cost-effective trimming solution for achieving the very highest amplifier/system performance.
The ALD2726E/ALD2726 dual operational amplifier features rail-to-rail input and output voltage ranges, tolerance to over-voltage input spikes of 300m V beyond supply rails, capacitive loading up to 25p F, extremely low input currents of 0.01p A typical, high open loop voltage gain,...
