It delivers a 1 µs settling time to ±½ LSB, which sets the maximum update rate for the output stage — useful for closed-loop control or waveform generation where the DAC must track the digital input within one microsecond. Integral and differential nonlinearity are each specified at ±1 LSB maximum. For a calibration technician, this means the output code-to-voltage relationship is guaranteed monotonic to within one least-significant bit across the full 12-bit range — no missing codes, and the transfer curve stays within a 0.024% error band at room temperature. ## SPI control and dual-supply power budget Data is written via an SPI-compatible serial interface. The digital supply accepts 5 V, while the analog supply operates from 11.4 V to 15.75 V. This split-rail arrangement lets the DAC swing its output current into a load referenced to a separate analog rail — common in industrial analog output modules where the loop supply is 12 V or 15 V. Because the output is current-unbuffered, the DAC's output current must be converted to a voltage by an external op-amp. The R-2R architecture gives inherently good linearity, but the external amplifier's offset and drift will add to the system error budget — a zero-drift op-amp is recommended for precision applications. ## Package, temperature grade, and compliance Housed in an 8-lead SOIC package, surface-mount, supplied in tube format. ROHS3 compliant — no restricted substances above the threshold limits.","metaTitle":"MAX543BCSA+ 12-Bit DAC, 1µs Settling, 8-SOIC","metaDescription":"Analog Devices MAX543BCSA+ 12-bit current-output DAC, SPI interface, ±1 LSB INL, 1µs settling, 8-SOIC.
