EPAD ULTRA MICROPOWER OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The
ALD1726E/ALD1726 is a monolithic rail-to-rail ultra-micropower
precision CMOS operational amplifier with integrated user programmable
EPAD (Electrically Programmable Analog Device) based offset voltage
adjustment.
The ALD1726E/ALD1726 is a direct replacement of the
ALD1706 operational amplifier, with the added feature of user-program-
mable 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 preci-
sion 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 ALD1726E/ALD1726 operational amplifier features rail-to-rail input
and output voltage ranges, tolerance to over-voltage input spikes of
300mV beyond supply rails, extremely low input currents of 0.01pA typical,
high open loop voltage gain, useful bandwidth of 200KHz, slew rate of 0.17
V/
s, and low typical supply current of 25A.
