Replacement verdict
Not a drop-in replacement
The AD780ARZ and AD7808BR are not functionally interchangeable; the AD780ARZ is a precision 2.5 V voltage reference, while the AD7808BR is an 8-bit multiplying D/A converter, so they differ in core function, package, and electrical characteristics and cannot serve as substitutes for one another.
Different device function
Different package type
