• Output Type: Rail-to-Rail
• Slew Rate: 0.04 V/µs
• Gain Bandwidth Product: 90 kHz
• Current - Input Bias: 2 nA
• Voltage - Input Offset: 250 µV
• Current - Supply: 14 µA (x2 Channels)
• Current - Output / Channel: 2.5 mA
• Voltage - Supply Span: 1.8 V to 5.5 V
• Operating Temperature Range: -40°C ~ 85°C

Mechanical Equivalence Criteria:

• Package / Case: 10-TFSOP, 10-MSOP (0.118", 3.00mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 10-uMAX/uSOP

Regulatory Equivalence Criteria:

Substitute parts must maintain identical electrical performance specifications, compatible physical packaging for PCB assembly, and equivalent regulatory classification to ensure direct functional replacement without circuit redesign or board-level modifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX4243EUB+ serves as the direct substitute for the obsolete MAX4243EUB. Both parts share identical electrical specifications and mechanical packaging, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.

Key Differentiation Factors:

Product Status: The MAX4243EUB is classified as obsolete with limited inventory availability (625 pcs). The MAX4243EUB+ maintains active production status with higher inventory levels (1158 pcs), ensuring long-term procurement reliability and supply chain continuity.

Regulatory Compliance: The MAX4243EUB carries RoHS non-compliant status, while the MAX4243EUB+ achieves ROHS3 compliance. For applications subject to RoHS directives or customer requirements mandating lead-free components, the MAX4243EUB+ is the appropriate selection.

Packaging Configuration: The MAX4243EUB is supplied in standard packaging, while the MAX4243EUB+ is supplied in tube packaging. Both configurations are compatible with standard surface-mount assembly processes.

Selection Criteria: Choose MAX4243EUB+ for new designs, production restarts, or applications requiring regulatory compliance. The MAX4243EUB may be retained for existing inventory management only where RoHS compliance is not mandated.

Frequently Asked Questions (FAQ)

Q: Are MAX4243EUB and MAX4243EUB+ electrically identical?

A: Yes. Both parts maintain identical electrical specifications including slew rate (0.04 V/µs), gain bandwidth product (90 kHz), input bias current (2 nA), input offset voltage (250 µV), supply current (14 µA per channel), and output current capability (2.5 mA per channel). Supply voltage range (1.8 V to 5.5 V) and operating temperature range (-40°C to 85°C) are identical.

Q: Can MAX4243EUB+ be used as a direct replacement for MAX4243EUB in existing designs?

A: Yes. The MAX4243EUB+ is pin-for-pin compatible with identical package dimensions (10-TFSOP, 10-MSOP, 0.118" width, 3.00mm). No circuit modifications or PCB layout changes are required for substitution.

Q: What is the primary reason to transition from MAX4243EUB to MAX4243EUB+?

A: The MAX4243EUB is obsolete with limited inventory. The MAX4243EUB+ maintains active production status, ensuring reliable long-term supply. Additionally, MAX4243EUB+ achieves ROHS3 compliance, meeting modern regulatory requirements.

Q: Are there any performance differences between the two parts?

A: No performance differences exist. Both parts deliver identical amplifier performance across all specified electrical parameters. The only differences are product status (obsolete vs. active) and RoHS compliance classification.

Q: What is the moisture sensitivity level for both parts?

A: Both MAX4243EUB and MAX4243EUB+ carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts subject to export control regulations?

A: Both parts are classified under ECCN EAR99, indicating standard commercial classification with no enhanced export restrictions. REACH status is unaffected for both parts.
