4. This register will latch an 8-bit value into an R-2R D/A to provide a range of 0-1.25 volts; accuracy

can be ±5% or more.

5. This location will contain the company identification number which will be used by software to

determine analog voltage curves; this register is read only.

6. This location will contain the stepping number of the part; this register is read only.

* This is a stress rating only and functional operation of the device at these or any other conditions above

those indicated in the operation sections of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods of time may affect reliability.

The Dallas Semiconductor DS1780 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 DS1780 is not exposed to environmental stresses, such as burn-in,

that some industrial applications require. For specific reliability information on this product, please
