10-bit DAC at 5V — single-supply span
The MAX5304CUA+ is a 10-bit digital-to-analog converter with voltage-buffered output, operating from a single 5V supply for both analog and digital rails. The output span equals the reference voltage — external reference only, no internal bandgap — so the full-scale range is set by the reference you feed into the REF pin.
SPI update rate and settling time
Data loads through a standard SPI interface. The typical settling time to ±0.5 LSB is 10 µs, which sets the maximum update rate at roughly 100 kHz for a full-scale step. For smaller code changes the output settles faster, but the 10 µs figure governs the worst-case throughput — important if this DAC feeds a closed-loop control system that updates every PWM cycle.
R-2R architecture — monotonicity and linearity
The R-2R ladder architecture gives inherent monotonicity — every increase in digital code produces a non-decreasing analog output. The DNL is ±1 LSB maximum, guaranteeing no missing codes at 10-bit resolution. INL is ±4 LSB max, adequate for general-purpose set-point and trim applications where absolute accuracy is less critical than step-size consistency.
