Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4559EEE is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the MAX4559EEE+, which maintains identical functional specifications including switch circuit configuration (SP4T), circuit count (2), on-state resistance (160Ohm), supply voltage ranges, switching characteristics, and package form factor (16-QSOP).

The key parameters governing substitution are:

• Switch circuit type and count (SP4T, 2 circuits)
• On-state resistance and channel matching (160Ohm, 2Ohm ΔRon)
• Supply voltage compatibility (2V ~ 12V single, ±2V ~ 6V dual)
• Switching performance (150ns Ton, 120ns Toff)
• Package and pinout (16-QSOP)

Parameter Comparison

Engineering Selection Recommendations

The MAX4559EEE+ is the direct active equivalent for the obsolete MAX4559EEE. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance: the MAX4559EEE+ is actively produced and ROHS3 compliant, whereas the MAX4559EEE is obsolete and RoHS non-compliant.

For new designs and production applications, the MAX4559EEE+ is the appropriate selection. Both parts maintain identical pinout, package footprint (16-QSOP), and functional performance, enabling direct substitution without circuit redesign. The MAX4559EEE+ offers improved regulatory alignment and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can MAX4559EEE+ directly replace MAX4559EEE in existing designs? A: Yes. The MAX4559EEE+ is electrically and mechanically identical to the MAX4559EEE. Pinout, package footprint, and all electrical parameters are equivalent, enabling direct substitution without PCB modification.

Q: What is the difference between MAX4559EEE and MAX4559EEE+? A: The primary differences are product status and compliance. The MAX4559EEE is obsolete and RoHS non-compliant. The MAX4559EEE+ is actively produced and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts? A: Both parts use the 16-QSOP package (16-SSOP, 0.154" width, 3.90mm). The MAX4559EEE is supplied in standard packaging, while the MAX4559EEE+ is supplied in Tube packaging. The physical component and pinout are identical.

Q: What supply voltage ranges are supported? A: Both parts support single supply operation (2V ~ 12V) and dual supply operation (±2V ~ 6V). Circuit design must operate within these specified ranges.

Q: Is the MAX4559EEE+ suitable for RoHS-compliant applications? A: Yes. The MAX4559EEE+ is ROHS3 compliant and suitable for applications requiring RoHS compliance. The obsolete MAX4559EEE is not RoHS compliant.
