16-bit precision DAC for industrial set-point and trim
The MAX5203BEUB+ is a single-channel 16-bit digital-to-analog converter from Analog Devices, delivering a voltage-buffered output via an SPI interface. Its 25 µs typical settling time suits closed-loop control and calibration trim applications where the DAC update rate must keep pace with the loop bandwidth. Rated over -40°C to +105°C, the device fits industrial enclosures, motor-drive feedback paths, and under-hood sensor interfaces where the ambient temperature exceeds the commercial 85°C ceiling.
Supply rails and linearity budget
The internal reference eliminates the external reference IC and its bypass capacitor, saving board area in a 10-pin MSOP footprint. Integral non-linearity is ±20 LSB max; differential non-linearity is ±2 LSB max. For a 16-bit DAC with a 3.3 V reference, 1 LSB equals roughly 50 µV — the ±2 LSB DNL guarantees monotonicity across the full output range, so the control loop sees no missing codes at the set point.
Package, delivery, and production status
Shipped in Tube format — suitable for hand-assembly or low-volume pick-and-place without reel fees. Analog Devices lists the MAX5203BEUB+ as Active with ROHS3 compliance.
