GENERAL DESCRIPTION

The ALD1721E is a monolithic rail-to-rail precision CMOS operational

amplifier with integrated user programmable EPAD (Electrically Programmable

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 incircuit

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 powerdown.

EPAD offers the circuit designer a convenient and cost-effective

trimming solution for achieving the very highest amplifier/system performance.

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/ms, and low typical supply current of 120mA.
