8-bit R-2R DAC with parallel interface
The MAX5480BCEE+ is an 8-bit multiplying DAC from Analog Devices, built on a classic R-2R ladder architecture with a parallel data interface. It delivers either a voltage or current output (unbuffered), and supports differential output for applications needing a balanced signal path. Settling time is 250 ns to within 1 LSB, making it fast enough for waveform generation, programmable references, and control-loop trim adjustments in instrumentation and industrial control. The device operates from a single 5 V supply for both analog and digital rails, simplifying power distribution in mixed-signal designs. The external reference input sets the full-scale output range, giving the designer control over the span independent of the supply. Integral non-linearity (INL) is ±0.5 LSB max, and differential non-linearity (DNL) is ±1 LSB max, guaranteeing monotonic performance across the 8-bit range. That matters for closed-loop systems where a non-monotonic transfer function can cause oscillation or hunting.
Board-fit: 16-SSOP footprint and temperature grade
Packaged in a 16-SSOP (3.90 mm width) and also specified for the 16-QSOP supplier package, the MAX5480BCEE+ is a surface-mount device suited for dense mixed-signal boards. The 0.154-inch body width fits standard SSOP land patterns; the QSOP variant is a drop-in alternative for tighter layouts. If your board sees -40°C or 85°C in the enclosure, look at the industrial-grade sibling in the same family. Supplied in a tube, the part is suitable for hand-assembly or low-volume production. For pick-and-place lines, verify tube-to-reel transfer or order the tape-and-reel variant if available.
Sourcing and compliance
It is ROHS3 compliant, meeting the latest restriction-of-hazardous-substances directive for lead-free assembly. As a single-source DAC from Analog Devices, there is no official second-source or pin-compatible alternative recorded. If you are qualifying a second source for BOM risk mitigation, the closest functional match would be another 8-bit R-2R DAC in a 16-pin SSOP from a different vendor, but the pinout and interface may differ — board review is required.
