DAC7811: Difference Between DAC8043U and DAC7811

Kato-san,

The two devices are somewhat similar, the most significant difference I see in the datasheets is that the DAC8043U is rated only for operation from -40C to 85C while the DAC7811 is rated from -40C to 125C. However, both device electrical characteristics tables are specified for their entire operating temperature range - that means the DAC7811 datasheet is showing an additional 40C of drift in the gain error figure compared to that of the DAC8043U, so the datasheets are not exactly comparable.

Overall it would look like the two devices have similar performance, except that the DAC7811 is a more modern device in a smaller package with wider operating temperature range.
