Active: In Production.

Description

The DS4303 is a nonvolatile (NV) electronically programmable voltage reference. The reference voltage is programmed in-circuit during factory calibration/programming. Programming the reference voltage, VOUT, is as simple as applying the desired voltage on VIN and toggling the adjust pin (ADJ-bar) to lock the VOUT voltage level indefinitely, even if the device is power cycled. The DS4303 replaces current cumbersome factory adjustment arrangements with a low-cost solution that can be adjusted using automated techniques. In addition, the DS4303 has the ability to be readjusted after the unit has been fully assembled and tested. This results in a much more flexible manufacturing arrangement, lower inventory costs, and a quicker time-to-market.

DS4303K EVALUATION BOARD
To facilitate evaluation of the DS4303 in its tiny SOT23 package, it is available mounted on a small (16mm x 10mm) evaluation board. The board includes a 0.1µF decoupling capacitor on the supply input. The part number for the evaluation board is DS4303K and it available as a free sample.
