Description

General part information

DS4303 Series

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 VINand toggling the adjust pin (ADJ-bar) to lock the VOUTvoltage 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.ApplicationsBias AdjustingFactory-Calibrated EquipmentOffset NullingPower AmplifiersPower-Supply CalibrationPressure BridgesThreshold Setting
