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

MOSFETsthatarehighlymatchedinthresholdvoltagesandotherelectrical

characteristics. For a given input voltage, the threshold voltage of a

MOSFET device determines its drain on-current, resulting in an on-

resistancecharacteristicthatcanbepreciselypresetandthencontrolledby

the input voltage very accurately.

• Precision matched electrically after

packaging

• Simple, elegant single-chip user option

to trim voltage/current values

• Excellent device matching characteristics

with or without additional electrical trim

• Remotely and electrically trim parameters

on circuits that are physically inaccessible

PIN CONFIGURATION

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.

TheseMOSFETdeviceshaveverylowinputcurrents, andasaresultavery

high input impedance (>10 Ohm). The gate voltage from a control source

, V

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.
