Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4800CXZ+ is determined by strict alignment with the following critical parameters:

• Switch Circuit Configuration: SPST - NO topology with 8 independent circuits
• Multiplexer Ratio: 1:1 channel configuration
• On-State Resistance: Maximum 38Ohm with channel-to-channel matching of 1.9Ohm
• Supply Voltage Compatibility: Single supply operation within 2.7V ~ 13.2V range
• Switching Performance: Maximum switching times of 5µs for both Ton and Toff
• Signal Integrity Parameters: Charge injection of 820pC, channel capacitance of 18pF, and crosstalk performance of -80dB @ 5MHz
• Leakage Specifications: Maximum off-state leakage current of 4µA
• Package Compatibility: 72-CSBGA (6x5.35) surface mount package
• Environmental & Compliance: Operating temperature range 0°C ~ 70°C, ROHS3 compliance, MSL Level 1, and REACH unaffected status

Parts meeting all these specifications are considered direct equivalents. Parts with identical electrical performance but different package configurations may be considered functional substitutes only when package compatibility is verified for the target application.

Parameter Comparison

Engineering Selection Recommendations

The MAX4800CXZ+ is an active production component with full ROHS3 compliance and REACH unaffected status, making it suitable for current and future design implementations. The part carries MSL Level 1 rating, indicating unlimited shelf life and minimal moisture sensitivity concerns during storage and handling.

When selecting equivalent parts, prioritize components with identical active product status to ensure long-term availability and consistent manufacturing quality. Verify that substitute parts maintain the same ROHS3 compliance certification and REACH status to satisfy regulatory requirements in target markets.

The 72-CSBGA (6x5.35) package specification is critical for PCB layout compatibility. Any substitute part must use this exact package configuration to ensure proper fit within existing board designs without requiring layout modifications.

Frequently Asked Questions (FAQ)

Q: What defines a direct equivalent for the MAX4800CXZ+?

A: A direct equivalent must match all electrical specifications including 8-circuit SPST-NO configuration, 38Ohm on-state resistance, 1:1 multiplexer ratio, 2.7V ~ 13.2V supply voltage range, 5µs switching times, 820pC charge injection, 18pF channel capacitance, 4µA maximum leakage current, and -80dB crosstalk performance. The part must also use the 72-CSBGA (6x5.35) package and maintain active product status with ROHS3 compliance.

Q: Can I use a substitute part with a different package type?

A: Package substitution is not recommended without complete PCB redesign. The MAX4800CXZ+ is specified for 72-CSBGA (6x5.35) surface mount configuration. Alternative packages would require layout modifications, re-routing, and re-validation of signal integrity characteristics.

Q: What is the significance of the 1.9Ohm channel-to-channel matching specification?

A: Channel-to-Channel Matching (ΔRon) of 1.9Ohm ensures consistent on-state resistance across all 8 circuits. This parameter is critical for applications requiring uniform signal attenuation or impedance matching across multiple channels. Substitute parts must maintain this specification to preserve circuit performance.

Q: Are there any temperature-related limitations for the MAX4800CXZ+?

A: The MAX4800CXZ+ operates within the 0°C ~ 70°C temperature range. Applications requiring extended temperature operation must use alternative components specified for wider temperature ranges. Substitute parts must support at minimum this same temperature specification.

Q: What does MSL Level 1 mean for component handling?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no moisture sensitivity concerns. The MAX4800CXZ+ can be stored and handled without special moisture control measures, simplifying inventory management and reducing component damage risk during manufacturing.

Q: How does the -80dB crosstalk specification impact circuit design?

A: Crosstalk of -80dB @ 5MHz indicates excellent channel isolation, meaning signal leakage between circuits is minimal at typical operating frequencies. This specification is essential for applications with sensitive analog signals or high-frequency switching. Substitute parts must maintain this crosstalk performance to prevent signal degradation.
