ADVANCED LINEAR DEVICES, INC. TM e ® EPAD D LE AB EN ALD1121E/ALD1123E QUAD/DUAL EPAD® PRECISION N-CHANNEL MATCHED PAIR MOSFET ARRAY GENERAL DESCRIPTION BENEFITS ALD1121E/ALD1123E are monolithic quad/dual EPAD® (Electrically Programmable Analog Device) N-channel MOSFETs with electrically adjustable threshold (turn-on) voltage. The ALD1121E/ALD1123E are precision matched and adjusted (e-trimmed) at the factory resulting in quad/dual MOSFETs that are highly matched in electrical characteristics. The ALD1123E has four (4) separate source pins. SN1, SN2 share a common substrate pin, V-1, which has to be connected to the most negative voltage potential. Likewise, SN3, SN4 share a common substrate pin, V-2, which has to be connected to the negative voltage potential for SN3, SN4. The ALD1121E has two (2) separate source pins (SN1, SN2). Both SN1, SN2 share a common substrate, pin 4, which has to be connected to the most negative voltage potential. 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. • Precision matched electrically after Using an ALD1121E/ALD1123E 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. 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. Since these devices are on the same monolithic chip, they also exhibit excellent tempco matching characteristics.

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.) • Usable in environmentally sealed circuits • No mechanical moving parts -- high G-shock tolerance • Improved reliability, dependability, dust and moisture resistance • Cost and labor savings • Small footprint for high board density applications 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. The ALD1121E/ALD1123E 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.
