12-bit resolution across eight channels — ±0.5 LSB INL ceiling
The AD5628ARUZ-2REEL7: Each of the eight DACs delivers 12-bit monotonic output with integral nonlinearity held to ±0.5 LSB maximum and differential nonlinearity at ±0.25 LSB maximum — no missing codes across the full temperature range. The string-DAC architecture keeps the output glitch energy low, which matters when the DAC drives a downstream amplifier or actuator directly without a sample-and-hold. Settling time is 7 µs typical to ±0.5 LSB, so updating all eight channels sequentially at 125 kHz per channel is feasible — the SPI clock rate and the host's interrupt latency, not the DAC itself, set the system throughput ceiling. An internal reference (1.25 V or 2.5 V, software-selectable) is included, so no external reference IC is needed for the common output spans.
