Looking for a comparator IC with programmable threshold

Hello,
I'm looking for an IC that provides the functionality of a a comparator 
or schmitt trigger with a digitally programmable threshold.

Ideally the IC has a single comparator channel which allows setting the 
threshold via an SPI interface. A supply voltage in the range of +-5V 
and an 8 Bit resolution would be perfect.

The best I have found so far is an MAX516 "Quad comparator with 
programmable threshold" 
(https://www.maximintegrated.com/en/products/analog/amplifiers/MAX516.html). 
The MAX 516 however has an parallel bus and does not really improve 
sizewise on a solution build with separate DAC and comparater ICs.

Does anyone by any chance have a suggestion for a part, or for better 
search terms?
