13-bit DAC with SPI — what it is and where it fits
The MAX5130BEEE+ is a 13-bit, single-channel, voltage-output DAC in a 16-QSOP package. It uses an R-2R ladder architecture and buffers the output internally. The SPI data interface uses three wires (SCLK, DIN, CS).
Industrial temperature range and supply
Rated for -40°C to 85°C, this part suits outdoor telecom cabinets, factory-floor PLC modules, and engine-bay-adjacent electronics that see temperature swings but not the full automotive under-hood range. Both analog and digital supplies run from a single 5 V rail, which simplifies the power design — no separate AVDD and DVDD voltages to generate.
Package and footprint
The 16-QSOP (0.154" body width) is a compact surface-mount package. The 3.90 mm width fits on tight PCB real estate. The part ships in a Tube.
