GENERAL DESCRIPTION
The ALD2726E/ALD2726 is a dual monolithic rail-to-rail precision CMOS
operational amplifier with integrated user programmable EPAD (Electri-
cally Programmable Analog Device) based offset voltage adjustment. The
ALD2726E/ALD2726 is a dual version of the ALD1726E/ALD2726 opera-
tional amplifier. Each ALD2721E/ALD2721 operational amplifier features
individual user-programming offset voltage trimming, resulting in signifi-
cantly 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 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
300mV beyond supply rails, capacitive loading up to 25pF, extremely low
input currents of 0.01pA typical, high open loop voltage gain, useful
bandwidth of 700KHz, slew rate of 0.7V/
s, and low typical supply current
of 50
A for both amplifiers.
