It converts serial data received over an SPI interface into an unbuffered voltage output, settling to within 1 LSB in 4 µs typical. Each of the two DACs shares a common external reference input, so the full-scale output range tracks the reference voltage applied. The unbuffered output means the load impedance must be high enough not to load the R-2R network — typically above 5 kΩ — or an external buffer is needed. ## Supply rails and temperature range The INL/DNL specification is ±0.9 LSB maximum — no minimum INL is listed, meaning the monotonicity guarantee is implicit in the R-2R architecture but not separately stated. For applications requiring guaranteed monotonic behavior across all codes, verify against the device's production test limits. Available in Tape & Reel (TR) or Cut Tape (CT) packaging, the part is suited for both prototype builds and production reels. The ROHS3 compliance status is confirmed, with no exemptions listed. No pin-compatible direct replacement is listed from the manufacturer. The dual-channel 8-bit voltage-output DAC segment has few drop-in alternatives — any substitution would require a board-level change to the SPI timing or reference circuit.","metaTitle":"MAX550ACUA+T 8-Bit DAC, 2-Ch, Voltage Out, SPI, 8-uMAX","metaDescription":"Analog Devices MAX550ACUA+T 8-bit voltage-output DAC, dual channel, SPI interface, 4µs settling, 8-uMAX package.
