Substitute Part Grouping Explanation

Substitution of the DAC8228FP is determined by strict equivalence across the following critical parameters: resolution (8 bits), dual converter configuration (2 channels), settling time (5µs), buffered voltage output topology, parallel data interface, external reference architecture, dual supply voltage range (12V ~ 15V for both analog and digital), linearity specifications (±1 LSB INL/DNL), R-2R converter architecture, operating temperature range (-40°C ~ 85°C), and 20-DIP through-hole package format.

The DAC8228FPZ qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction between these parts is product status and packaging configuration.
