I couldn't tell you about the 7980, but the OEM version, the 88780,
was available with multiple options including single-ended and
(high-voltage) differential. Most of the ones I've seen in surplus
were differential. Unfortunately that is NOT compatible with LVD
(low-voltage differential).

There used to be active adapters between single-ended and high-voltage
differential, but they were uncommon and expensive.
