12-bit DAC with buffered voltage output and SPI
The Maxim Integrated MAX5302EUA+T is a single-channel 12-bit digital-to-analog converter with a buffered voltage output and an R-2R ladder architecture. It communicates over an SPI data interface, making it straightforward to hook into most microcontrollers or DSPs. The part operates from a single 5V supply for both analog and digital rails, which simplifies power routing on the board. Typical applications include industrial process control, programmable voltage sources, and instrumentation where a compact, moderate-speed DAC is needed. The -40°C to 85°C temperature range covers most industrial and outdoor telecom environments without needing a mil-spec part.
Settling time and linearity — what they mean for your loop
Integral nonlinearity is ±4 LSB max, and differential nonlinearity is ±1 LSB max.
Package and rework considerations
The 8-uMAX/uSOP package (3.00 mm body width, 0.118" pitch) is a common footprint that reflows cleanly with a standard hot-air station.
Lifecycle and sourcing
The MAX5302EUA+T is listed as Active with ROHS3 compliance.
