12-bit voltage-output DAC in 8-SOIC
The MAX539ACSA+ is a single-channel, 12-bit digital-to-analog converter with a voltage-buffered output, built on an R-2R ladder architecture. It is cataloged under Microcontrollers & Processors (MCU / MPU / DSP) but functions as a precision analog output stage for embedded control systems. Key parametrics include a 25 µs typical settling time, SPI data interface, and an INL of ±0.5 LSB (max) with DNL of ±1 LSB (max). These figures define the DAC's suitability for closed-loop control where monotonicity and fast update rates are required.
The device operates from a single 5 V supply for both analog and digital sections. Reference type is external, meaning the output full-scale accuracy depends on the external reference voltage stability and noise. The differential output is not provided; this is a single-ended voltage output part.
Package and board integration
Tube packaging is standard for this variant; the tube quantity should be confirmed at order to match the pick-and-place feeder setup.
For a current-production DAC, the supply chain is stable through authorized and independent distribution channels.
