ALD1721EPA datasheet

Description :

DESCRIPTION
The ALD1721E/ALD1721 is a monolithic rail-to-rail precision CMOS
operational amplifier with integrated user programmable EPAD (Electri
cally Programmable Analog Device) based offset voltage adjustment. The
ALD1721E/ALD1721 operational amplifier is a direct replacement of the
ALD1701 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.
