Replacement verdict
Not a drop-in replacement
The AD783JRZ and AD7834AR are not drop-in replacements for one another. Although both are analog sample-and-hold amplifiers, they differ in channel count, package type, and pinout, and the AD7834AR requires external hold capacitors that the AD783JRZ integrates internally. Each of the four functional viewpoints shows a low match, so a direct substitution is not feasible without circuit and layout redesign.
Different channel count
Different package type
Different pinout
