AV Electronically Programmable
Voltage Reference 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) 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. Features
