Quad 10-bit DAC with buffered voltage output
The MAX5841MEUB+ from Analog Devices (formerly Maxim Integrated) is a 10-bit, 4-channel digital-to-analog converter with buffered voltage output. It uses a string DAC architecture that guarantees monotonic performance and low glitch energy, making it a clean fit for set-point generation, sensor calibration, and programmable voltage references in industrial control and instrumentation. Communication runs over an I²C interface, keeping the pin count to just 10 pins in a compact 3.00 mm-wide 10-uMAX/uSOP package. The four DAC channels share a common external reference, so the output span is set by the reference voltage, not the supply rail.
The 12 µs settling time to ±0.5 LSB. That is fast enough for trimming power supplies, setting comparator thresholds, or updating analog set-points in a motor drive. Because the four channels share one I²C bus, the effective per-channel update rate drops when all four are written in sequence. A single write to one channel takes about 12 µs.
±0.5 LSB INL/DNL — no missing codes guaranteed
The ±0.5 LSB maximum INL and DNL means every code step is monotonic and no output code is skipped. For a calibration DAC trimming a voltage reference or a sensor offset, that guarantee avoids the headache of a non-monotonic transfer curve causing control-loop oscillation.
