GENERAL DESCRIPTION
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 o-resistance characteristic that can be precisely preset and then controlled by the input voltage very accurately.

BenefitS
• 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
