MAX4712CSE+ Equivalent & Substitute Parts

Part Overview

The MAX4712CSE+ is a 4-circuit SPST-NO (Single Pole Single Throw - Normally Open) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This device functions as a precision electronic switch with 25Ohm on-state resistance, designed for signal routing and multiplexing applications in analog and mixed-signal systems. The part is currently in active production status with 864 units available in new original stock. Alternative part identification becomes necessary for supply chain continuity, design flexibility, or when specific packaging or lead-time requirements necessitate equivalent component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4712CSE+ is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Switch circuit topology: SPST - NO (4 independent circuits)
• On-state resistance: 25Ohm maximum
• Channel-to-channel matching: 200mOhm maximum
• Supply voltage compatibility: Single supply 2.7V ~ 11V or dual supply ±2.7V ~ 5.5V

Performance Parameters:

• Switch timing: Ton ≤ 125ns, Toff ≤ 80ns
• Charge injection: 25pC
• Channel capacitance: 8pF (both CS(off) and CD(off))
• Leakage current: 500pA maximum
• Crosstalk: -87dB @ 1MHz

Physical & Environmental Parameters:

• Package: 16-SOIC surface mount
• Operating temperature range: 0°C ~ 70°C
• Compliance: ROHS3, MSL Level 1

A part qualifies as a direct substitute only when all parameters match or exceed the specifications of the MAX4712CSE+. No parameter degradation is acceptable for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The MAX4712CSE+ is an active production component with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL Level 1), indicating robust manufacturing and environmental qualification. Selection of this part or its direct equivalents is supported by:

• Active product status ensuring continued availability and manufacturing support
• Full regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification)
• Established supply chain with 864 units in new original stock
• Proven performance specifications across all electrical and thermal parameters

Direct substitution is appropriate when component specifications must remain unchanged. No alternative part numbers with different electrical or mechanical characteristics are presented in this reference, as the provided substitute list contains only the identical part number.

Frequently Asked Questions (FAQ)

Q: What defines a direct substitute for the MAX4712CSE+?

A: A direct substitute must match all electrical parameters (on-state resistance, supply voltage, switch timing, leakage current, crosstalk), physical specifications (16-SOIC package, surface mount), and environmental ratings (0°C ~ 70°C operating range, MSL Level 1). No parameter degradation is acceptable.

Q: Can the MAX4712CSE+ be used in applications requiring different supply voltages?

A: The MAX4712CSE+ supports single supply operation from 2.7V to 11V or dual supply operation from ±2.7V to ±5.5V. Application circuit design must conform to one of these supply configurations. Substitutes must maintain identical voltage specifications.

Q: Is the 16-SOIC package critical for substitution?

A: Yes. The 16-SOIC (0.154", 3.90mm width) surface mount package is a defining characteristic. Any substitute must use the identical package to ensure PCB compatibility, thermal performance, and electrical characteristics. Package changes require full circuit re-evaluation.

Q: What is the significance of the 25pC charge injection specification?

A: Charge injection represents the amount of charge transferred to the signal path when the switch transitions. The 25pC specification is critical for precision analog applications. Substitutes must maintain this value to prevent signal distortion or offset errors in sensitive circuits.

Q: Does the -87dB crosstalk specification affect substitute selection?

A: Yes. Crosstalk performance at 1MHz indicates isolation between independent switch circuits. This specification must be maintained in substitutes to ensure signal integrity in multi-channel applications. Degraded crosstalk performance may introduce unwanted signal coupling.

Q: Are there any lead-time or availability considerations for the MAX4712CSE+?

A: Current inventory shows 864 units in new original stock. Availability status should be confirmed with the supplier for long-term production requirements. Product status is active, indicating ongoing manufacturing support.
