GENERAL DESCRIPTION
ALD1108E/ALD1110E are monolithic quad/dual EPADs (Electrically
Programmable Analog Device) that utilize CMOS MOSFET with elec-
trically programmable threshold voltage. For a given input voltage,
changing the threshold turn-on voltage of a MOSFET device precisely
changes its drain on-current, resulting in an on-resistance characteris-
tic that can be precisely set and controlled. Used as an in-circuit element
for trimming or setting a combination of voltage and/or current charac-
teristics, it can be programmed via a Personal Computer remotely and
automatically via software control. Once programmed and set, the set
voltage and current levels are stored indefinitely inside the device as a
precisely controlled nonvolatile stored charge, which is not affected
during normal operation of the device, even after power has been turned
off.
The ALD1108E/ALD1110E are devices built with ALD's EPAD technol-
ogy, an electrically programmable device technology refined for analog
applications. The ALD1108E/ALD1110E functions like a regular MOSFET
transistor except with precise user preset threshold voltage. Using the
ALD1108E/ALD1110E is simple and straight forward. The device is
extremely versatile as a circuit element and design component. It
presents the user with a wealth of possible applications, limited only by
the imagination of the user and the many ways an analog MOSFET
device can be used as a circuit design element. The ALD1108E/
ALD1110E do not need other active circuitry for functionality.
The basic device is a monotonically adjustable device which means the
device can normally be programmed to increase in threshold voltage
and to decrease in drain-on current as a function of a given input bias
voltage. Once adjusted, the voltage and current conditions are perma-
nent and not reversible. However, a given EPAD device can be adjusted
many times to continually increase the threshold voltage. A pair of EPAD
devices can also be connected such that one device is used to adjust a
parameter in one direction and the other device is used to adjust the
same parameter in the other direction.
The ALD1108E/ALD1110E can be pre-programmed with the ALD
EPAD programmer to obtain the desired voltage and current levels. Or,
they can be programmed as an active in-system element in a user
system, via user designed interface circuitry. For more information, see
Application Note AN1108.
