GENERAL DESCRIPTION
The ALD1721E is a monolithic rail-to-rail precision CMOS operational
amplifier with integrated user programmable EPAD (Electrically Program-
mable 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 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 ALD1721E 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 50pF, 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 120A.
