The MAX5222EKA+T is a dual 8-bit voltage-output DAC from Analog Devices, built around an R-2R ladder architecture. It packs two independent converters into a SOT-23-8 package, each with a buffered voltage output that settles in 10 µs typical. The SPI data interface keeps pin count low — three wires for the serial clock, data in, and chip select — which is why this part fits on small mixed-signal boards where board area is the constraint. The reference is external, meaning the output full-scale is set by the voltage you apply to the REF pin. The SOT-23-8 footprint is a standard surface-mount package that reflows cleanly and is easy to inspect — no hidden balls, no underfill needed.

Frequently asked questions
Does MAX5222EKA+T require an external reference voltage?
Yes, the reference type is external. You supply the reference voltage on the REF pin, which sets the output full-scale span. This lets you scale the output range independently of the supply voltage.
