Electronically Programmable  
Voltage Reference  
General Description  
Features  
The DS4303 is a nonvolatile (NV) electronically pro-  
grammable voltage reference. The reference voltage is  
programmed in-circuit during factory calibration/  
programming. Programming the reference voltage,  
ꢀ Precise Electronically Adjustable Voltage  
Reference  
ꢀ Enables Automated Factory Trimming of Devices  
Needing Voltage Adjustment  
V

, is as simple as applying the desired voltage on  
OUT  
and toggling the adjust pin (ADJ) to lock the V  
IN  
OUT  
ꢀ Can be Adjusted to Within 1mV  
voltage level indefinitely, even if the device is power  
cycled. The DS4303 replaces current cumbersome fac-  
tory 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 arrange-  
ment, lower inventory costs, and a quicker time-to-market.
