... OPERATION The DS1804 is a single nonvolatile potentiometer. The device has a total of 100 tap-points including the L- and H- terminals. A total of 99 resistive segments exist between the L- and H- terminals. These tap- points are accessible to the W-terminal, whose position is controlled via a three-terminal control port. A block diagram of the DS1804 is shown in Figure 1. ...

... However, on power-up the wiper-position will be indeterminate. ONE-TIME PROGRAMMABILITY (OTP) The DS1804 can be easily used as an OTP device. The user of the DS1804 can trim the desired value of the wiper position and set this position for storage as described above. Any activity through the three- ...

... Insert A (Burn-in Disclaimer) The Dallas Semiconductor DS1804 is built to the highest quality standards and manufactured for long term reliability. All Dallas Semiconductor devices are made using the same quality materials and manufacturing methods. However, the flip-chip package version of the DS1804 is not exposed to environmental stresses, such as burn-in, that some industrial applications require ...
