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

The DS4305 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 (active-low ADJ) to lock the VOUTvoltage level indefinitely, even if the device is power cycled.

The DS4412 contains two I²C adjustable-current DACs that are each capable of sinking or sourcing current. Each output has 15 sink and 15 source settings that are programmed by I²C interface. The full-scale range and step size of each output is determined by an external resistor that can adjust the output current over a 4:1 range.The output pins, OUT0 and OUT1, power-up in a high-impedance state.ApplicationsAdjustable Current Sink or SourcePower-Supply AdjustmentPower-Supply Margining

The DS4422 and DS4424 contain two or four I²C programmable current DACs that are each capable of sinking and sourcing current up to 200μA. Each DAC output has 127 sink and 127 source settings that are programmed using the I²C interface. The current DAC outputs power up in a high-impedance state.ApplicationsAdjustable Current Sink or SourcePower-Supply AdjustmentPower-Supply Margining
