... The DS4305 replaces current cumbersome fac- tory adjustment arrangements with a low-cost solution that can be adjusted using automated techniques. In addition, the DS4305 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 ...

... The DS4305 output voltage can be adjusted over almost the entire operating supply range of the device, and it can be precisely set to with- in ±1.5mV. A graphical description of the DS4305 is provided in the block diagram. During factory calibration, a simple adjustment proce- dure must be followed. This entire procedure includes ...

... The DS4305 replaces this cum- bersome arrangement with a solution that is capable of being adjusted by automated techniques. An additional benefit of the DS4305 is the ability to provide a much lower voltage (down to 300mV) than is possible with pin, (2) control the IN shunt voltage references ...
