Product details

It uses an R-2R ladder architecture with an on-chip output buffer, giving you a clean analog voltage from a digital SPI word. The part runs on a single 5 V supply rail for both analog and digital sections, which simplifies the power tree on a legacy 5 V board or a mixed-signal design where the ADC and DAC share a rail. The typical settling time is 25 µs. The external reference input sets the output span independent of the supply.

It is not specified for automotive or extended industrial environments where the ambient swings below freezing or above 70°C.

Housed in an 8-pin SOIC (0.154" body width), the MAX515CSA+ is a standard surface-mount part that reflows easily and is straightforward to hand-solder with a fine tip. No thermal pad, no exposed paddle — just eight pins.

Frequently asked questions

What is the settling time of MAX515CSA+?

The typical settling time is 25 µs to 1 LSB for a full-scale step. This makes it suitable for control-loop updates and set-point adjustments at rates up to about 40 kHz.

Does MAX515CSA+ require an external reference?

Yes, the reference input is external. You supply the reference voltage that sets the full-scale output range, which gives flexibility to scale the output independently of the 5 V supply.

Is MAX515CSA+ compatible with 3.3 V logic?

The digital supply is specified at 5 V, and the SPI input thresholds are CMOS/TTL-compatible. Driving the SPI lines from a 3.3 V MCU may not meet the minimum VIH of the DAC at 5 V VDD — check the logic thresholds in the datasheet or use a level translator for reliable operation.
