What this DAC is and where it fits
The Maxim MAX503CWG+ is a 10-bit digital-to-analog converter with a buffered voltage output and an R-2R ladder architecture. It takes a parallel digital word and converts it to an analog voltage, settling to within 1 LSB in 25 µs typical — fast enough for process-control setpoints, motor-drive reference ramps, or ATE forcing functions that update in the tens of kilohertz range. The single DAC channel uses an external or internal reference, and the output is rail-to-rail capable on a ±5 V analog supply with a separate 5 V digital supply.
Key ratings and what they mean for your BOM
The 25 µs settling time sets the maximum update rate: you can drive a new output value every 25 µs. The ±0.5 LSB max INL and ±1 LSB max DNL mean the transfer curve stays monotonic and linear to within half a least-significant bit.
Lifecycle and sourcing
This part carries an Active lifecycle status and is ROHS3 compliant. No last-time-buy or end-of-life notice is on record.
Package and handling
The MAX503CWG+ comes in a 24-pin SOIC wide-body (7.50 mm width) and ships in a tube. Surface-mount, so it needs a reflow profile — not a field-swap candidate without a hot-air station. The wide-body SOIC is easier to hand-solder than the narrow version, but still requires a steady hand and a fine tip. Orientation is marked by pin 1 dimple on the package top; the tube keeps the parts aligned for pick-and-place. No ESD-sensitive handling beyond standard CMOS precautions.
