Product details

12-bit SPI DAC — settling time and package fit

The MAX551AEUB+ is a single-channel, 12-bit digital-to-analog converter with a current-unbuffered output and R-2R ladder architecture. It communicates over an SPI data interface, settling to within ±0.5 LSB INL/DNL in 1 µs — fast enough for closed-loop control loops updating at hundreds of kHz. Housed in a 10-pin TFSOP/MSOP package (3.00 mm body width), it mounts on the board as a 10-uMAX/uSOP footprint. Supply rails are clean: both analog and digital sections run from a single 5 V rail. The external reference pin lets you set the full-scale output voltage independent of the supply, which is useful when the DAC drives a downstream circuit with a different voltage ceiling.

The package ships in tubes, which is the standard delivery format for this MSOP body size.

Frequently asked questions

What is the output type and data interface of MAX551AEUB+?

It provides a current-unbuffered output and uses an SPI data interface. The R-2R architecture means the output impedance is code-dependent, so a following amplifier is typically required for voltage-mode operation.

What package does MAX551AEUB+ come in?

The part is supplied in a 10-pin TFSOP/MSOP package (3.00 mm width), also referred to as the 10-uMAX/uSOP supplier device package. It ships in tubes.
