Type of DAC in 8085 microprocessor?

None.

A microprocessor is just the processing core - ALU, registers, microcode sequencers, buses, etc.

A microCONTROLLER will have peripherals built into the same package and connected to a microprocessor.

You will need to check with the specific vendor to see what peripherals are available with which core.

Currently, the 8051 is probably the longest lasting, most used 8 bit processor. I suggest looking at data sheets from the following companies: Atmel, Philips, Infineon, and Texas Instruments.
