Its R-2R ladder architecture and internal reference eliminate the need for external trim resistors or a reference IC, reducing BOM count and calibration steps on the production line. Operating from a single supply of 4.5 V to 16.5 V on both the analog and digital rails, it powers directly from a common 5 V or 12 V bus without a separate analog rail. The parallel byte-wide data interface simplifies connection to any 8-bit microcontroller or FPGA without a serial-to-parallel conversion stage. ## Hermetic ceramic package and military temperature range Housed in a 16-lead hermetic ceramic DIP (16-CDIP, 0.300\" body width), the AD558SD is built for environments where moisture ingress and thermal cycling kill plastic-packaged parts. The -55°C to 125°C operating range covers the full military/aerospace temperature envelope — avionics bay, engine-mounted electronics, or satellite payloads that see cold-soak at one extreme and component self-heating at the other. Integral nonlinearity is specified at ±0.75 LSB maximum — better than the ±1 LSB typical for many 8-bit DACs, meaning the output voltage stays within a half-LSB of the ideal transfer function across the full temperature range without trimming. No missing codes are guaranteed over the military temperature window. No second-source or official successor is listed — the AD558SD is the singular 8-bit DACPORT in this package and temperature grade, so a BOM drop-in replacement is not available from the same manufacturer without a package or resolution change.","metaTitle":"AD558SD DACPORT 8-Bit DAC, -55°C to 125°C, CDIP","metaDescription":"Active Analog Devices AD558SD 8-bit voltage-output DAC.
