Parameter Comparison

Engineering Selection Recommendations

The MAX512CPD+ is the direct functional equivalent of the MAX512CPD. Both components share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product lifecycle status: the MAX512CPD is obsolete, while the MAX512CPD+ maintains active production status.

For new designs and ongoing procurement, the MAX512CPD+ is the appropriate selection. This part offers the same performance characteristics while providing access to current manufacturing and supply chain support. Additionally, the MAX512CPD+ carries ROHS3 compliance certification, whereas the original MAX512CPD is RoHS non-compliant. This compliance difference may be relevant for applications subject to environmental or regulatory requirements.

Both parts are manufactured by the same supplier and utilize identical R-2R architecture with external reference configuration, ensuring seamless integration into existing circuit designs without modification.
