GENERAL DESCRIPTION
The ALD1726E is a monolithic rail-to-rail ultra-micropower precision
CMOS operational amplifier with integrated user programmable EPAD
(Electrically Programmable Analog Device) based offset voltage adjust-
ment. The ALD1726E is a direct replacement of the ALD1706 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 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 perfor-
mance.
The ALD1726E 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 0.17V/
s, and low
typical supply current of 25
A.
