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 on- resistance characteristic that can be precisely preset and then controlled by the input voltage very accurately. 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 (>10 12 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. eEPAD TM N ABLED E ADVANCED LINEAR D EVICES, INC.

• Neural networks Optional EPAD Threshold Voltage Trimming by User 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 on- resistance 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. 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 in- system element in a user system, via user designed interface circuitry. P N1 , 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.

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.
