What this quad DAC delivers
The Analog Devices MAX533BEEE+ is a quad 8-bit voltage-output DAC in a 16-QSOP package. It communicates over SPI, settles to within 1 LSB in 6 µs typical, and runs from a single 2.7 V to 3.6 V supply — same rail for analog and digital. The string-DAC architecture keeps the output monotonic, and the buffered outputs can drive moderate loads directly without an external op-amp. This part is a fit for trim pots, set-point generation, and low-speed control loops where four independent voltage outputs are needed in a small footprint.
Package and rework realities
The 16-QSOP (3.90 mm body width) is a fine-pitch SSOP derivative. No exposed pad underneath, so rework is straightforward — heat from the top, lift when the solder flows, and clean the pads.
Supply and temperature range
Single-supply operation from 2.7 V to 3.6 V simplifies the power rail — no negative supply needed. The -40°C to 85°C range covers industrial and outdoor telecom environments. External reference required, so the reference voltage sets the full-scale output; pick a stable reference if the application sees temperature swings.
