Quad 8-bit DAC with I²C bus
The MAX520ACAP+ is a quad 8-bit digital-to-analog converter from Analog Devices, packing four independent DACs in a single 20-SSOP package. Each channel delivers a voltage output via an R-2R ladder architecture, with a typical settling time of 2 µs — fast enough for closed-loop trim or set-point control in a mixed-signal system. Communication runs over a standard I²C serial interface, keeping the pin count low. Both the analog and digital supply rails run at 5 V, simplifying the power plane in a single-5V system.
Accuracy and temperature range
Integral and differential non-linearity are each specified at ±1 LSB maximum — the output stays monotonic across the full 8-bit range, and the code-to-code step error is bounded within one LSB. That matters for applications like programmable voltage references or bias control where a missing code would cause a glitch in the controlled loop. For a bench instrument, lab controller, or office-environment automation board, the grade fits without derating concerns.
Sourcing and compliance
RoHS3 compliance is confirmed, so the part meets the latest EU restriction directive for lead and other hazardous substances. No additional compliance documentation (REACH, UL, IEC) is listed in the available records.
