Voltage Sample and Infinite Hold
General Description
The DS4303 is a nonvolatile (NV) sample and infinite-
hold adjustable voltage reference. The reference volt-
age is programmed in-circuit during factory calibration/
programming. Programming the reference voltage,
V
OUT
, is as simple as applying the desired voltage on
V
IN
and toggling the adjust pin (ADJ) to lock the V
OUT
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.
