It converts a serial SPI word into an analog output voltage with a 14 µs typical settling time to ±0.5 LSB. The reference is external, so the absolute output accuracy and temperature drift are determined by the reference voltage source you pair with it — not by an internal bandgap. This gives you control over the system accuracy budget but also means the reference's noise and drift directly appear at the output. ## Accuracy budget: INL, DNL, and monotonicity Integral non-linearity is ±4 LSB maximum, which at 5 V reference and 12 bits (1.22 mV per LSB) means the output can deviate from the ideal transfer by up to 4.88 mV at any code. That is the error budget a calibration technician would account for in a production test limit. Differential non-linearity is ±1 LSB maximum, guaranteeing monotonicity — every increase in digital code produces a positive or zero voltage step, never a negative step. This is critical for closed-loop control where a non-monotonic DAC would cause the loop to reverse direction momentarily. The R-2R architecture inherently provides low glitch energy at major-code transitions compared to segmented architectures, which matters when the DAC drives a sample-and-hold or a modulator that is sensitive to transient spikes. ## Settling time and update rate — what 14 µs means for your loop The 14 µs typical settling time to ±0.5 LSB sets the maximum update rate at roughly 71 kHz for a full-scale step. For a control loop running at 10 kHz, the DAC settles in about one-seventh of the sample period, leaving margin for the ADC conversion and the control algorithm. The SPI interface runs at standard clock rates — the settling time, not the serial clock, is the throughput bottleneck. A 10 MHz SPI clock loads a 16-bit word (12 data + control bits) in 1.6 µs, after which the DAC needs the full 14 µs to settle before the next conversion starts. ## Package, temperature grade, and board integration The supplier device package is 8-uMAX/uSOP, which is the standard Maxim thin MSOP variant. Mounting is surface-mount only; the tube packaging is suitable for prototype builds and low-volume production but not for automated tape-and-reel feeders without manual loading. ## Active lifecycle and compliance status Because the part is active and the reference is external, the only long-term drift concern is the external reference component — the DAC itself has no aging mechanism that affects the transfer function beyond the initial INL/DNL tolerance.","metaTitle":"MAX5302CUA+ 12-bit DAC, SPI, Voltage-Out, 8-uMAX","metaDescription":"MAX5302CUA+ 12-bit voltage-output DAC with SPI interface, 14µs settling, ±4 LSB INL, single 5V supply.
