Replacement verdict
Not a drop-in replacement
The AD780BRZ and AD7805BR are not functionally interchangeable: the AD780BRZ is a precision 2.5 V/3.0 V voltage reference in an SOIC-8 package, while the AD7805BR is a quad 10-bit voltage-output DAC in a wide-body SOIC-28 package. Their core functions, channel counts, pinouts, and footprints differ fundamentally, so the AD7805BR cannot serve as a substitute for the AD780BRZ in an existing design.
Different device function
Different channel count
Different package and footprint
Different pinout
