DS1780 Datasheet, PDF (22/28 Pages) Dallas Semiconductor – CPU Peripheral Monitor

DS1780
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.

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
