Detailed Description

Nonvolatile Sample and Infinite-Hold Adjustable Voltage Reference for Automated Factory Calibration

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, V_OUT, is as simple as applying the desired voltage on V_IN and toggling the adjust pin (ADJ-bar) to lock the V_OUT 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.
