Product details

12-bit voltage-output DAC with SPI — what it is and where it fits

The Maxim MAX538BCSA+ is a single-channel, 12-bit digital-to-analog converter with a buffered voltage output and an R-2R ladder architecture. It communicates over a standard SPI interface.

Supply rails and temperature — what the ratings mean for the BOM

Both the analog and digital supply rails are tied to a single 5 V rail. The operating temperature range is 0°C to 70°C.

Package and handling

Housed in an 8-pin SOIC package with a 3.90 mm body width — the standard narrow SOIC footprint that every PCB layout tool has in its library. Surface-mount assembly with no exposed pad, so no thermal-via stitching needed. The part ships in a Tube, which is the typical through-hole-friendly format for prototype and low-volume builds.

Lifecycle and sourcing

The MAX538BCSA+ carries an Active lifecycle status and is ROHS3 compliant. For BOM planning, there is no imminent obsolescence risk.

Frequently asked questions

How does MAX538BCSA+ compare to MAX538AESA+?

The MAX538AESA+ is the same 12-bit SPI DAC but in an extended temperature range (-40°C to +85°C) versus the commercial 0°C to 70°C range of the MAX538BCSA+. If your design needs to operate below freezing or above 70°C ambient, the AESA+ variant is the correct choice; otherwise the BCSA+ is functionally identical at a lower cost.

What is the output type of MAX538BCSA+?

The MAX538BCSA+ has a buffered voltage output, meaning the DAC output is internally buffered with an op-amp, so it can drive moderate loads directly without an external buffer.
