Product details

It uses an R-2R ladder architecture and communicates over an I²C interface.

The 6 µs typical settling time to ±½ LSB defines how fast the output can move from one code to another. For a full-scale step, the output settles in 6 µs typical.

Package and supply — board-level fit

Both analog and digital supply pins run from the same 5 V rail.

Linearity error — INL and DNL

The integral non-linearity (INL) is specified at ±1.5 LSB maximum, and the differential non-linearity (DNL) at ±1 LSB maximum. For an 8-bit DAC, ±1.5 LSB INL means the actual output can deviate from the ideal straight line.

It is ROHS3 compliant.

Frequently asked questions

How many DAC channels does MAX518BCSA+T have?

It has two independent DAC channels in a single 8-pin SOIC package.

Is MAX518BCSA+T RoHS compliant?

Yes, it is ROHS3 compliant.

What is the reference type for MAX518BCSA+T?

The reference type is external — the output voltage range is set by the voltage applied to the REF pin.

What is the difference between MAX518BCSA+T and MAX519BCSA+T?

The MAX519BCSA+T is a dual 8-bit DAC as well, but it includes an internal reference and operates from a wider supply range (5 V ±10% vs 5 V). The MAX518BCSA+T requires an external reference, which gives the designer control over the output voltage range but adds a component. Both use I²C and share the same 8-SOIC footprint, so they are pin-compatible — the choice comes down to whether you want the reference on-chip or off-chip.
