ALD1108E/ALD1110E
QUAD/DUAL ELECTRICALLY PROGRAMMABLE ANALOG DEVICE (EPAD™)
GENERAL DESCRIPTION
BENEFITS
ALD1108E/ALD1110E are monolithic quad/dual EPAD® (Electrically
Programmable Analog Device) N-channel MOSFETs with electrically
adjustable threshold (turn-on) voltage. The ALD1108E/ALD1110E are
matched and adjusted (e-trimmed) at the factory resulting in quad/dual
MOSFETs that are highly matched in threshold voltages and other electrical
characteristics. For a given input voltage, the threshold voltage of a
MOSFET device determines its drain on-current, resulting in an onresistance characteristic that can be precisely preset and then controlled by
the input voltage very accurately.
• Precision matched electrically after
Using an ALD1108E/ALD1110E is simple and straight forward. The
MOSFETs function as n-channel MOSFETs, except that all the devices
have exceptional matching to each other in electrical characteristics. Since
these devices are on the same monolithic chip, they also exhibit excellent
tempco matching characteristics.
These MOSFET devices have very low input currents, and as a result a very
high input impedance (>1012 Ohm). The gate voltage from a control source
can drive many MOSFET inputs with practically no loading effects. Used in
precision current mirror or current multiplier applications, they can be used
to provide a current source over a 100nA to 3mA range, and with either a
positive, negative or zero tempco.

Optional EPAD Threshold Voltage Trimming by User
BENEFITS (cont.)
The basic EPAD MOSFET device is a monotonically
adjustable device, which means the device can normally
be e-trimmed to increase in threshold voltage and to
decrease in drain-on current as a function of a given input
bias voltage. Used as an in-circuit element for trimming or
setting a combination of voltage, current and/or onresistance characteristics, it can be set up to be e-trimmed
remotely and automatically. Once e-trimmed, the set
voltage and current levels are stored indefinitely inside the
device as a nonvolatile stored charge, which is not affected
during normal operation of the device, even when power is
turned off. A given EPAD device can be adjusted many
times to continually increase its threshold voltage. A pair
of EPAD devices can also be connected differentially 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.
• Usable in environmentally sealed circuits
• No mechanical moving parts -- high G-shock
The ALD1108E/ALD1110E can be e-trimmed with an ALD
EPAD programmer to obtain the desired voltage and
current levels. They can also be e-trimmed as an active insystem element in a user system, via user designed
interface circuitry. PN1, PN2, etc., are pins required for
optional e-trim of respective MOSFET devices. If unused,
these pins are to be connected to V- or ground. For more
information, see Application Note AN1108.

NOTES:
1. Supply voltage is limited by Threshold Voltage. V+ must be the most positive supply rail and V- must be at the most negative supply rail. Source
terminals other than those labeled as V- can be at any voltage between V- and V+.
2. Initial Threshold Voltage is set at the factory. If no EPAD Vt trimming is intended by user, then this is also the final or permanent threshold voltage
value.
3. Initial and Final values are the same unless deliberately changed by user.
4. These parameters apply only when Vt of one or more of the devices are to be changed by user.
