DS4303 Overview
The DS4303 is a nonvolatile (NV) sample and infinitehold adjustable 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) to lock the VOUT voltage level indefinitely, even if the device is power cycled.
