• Package Compatibility: 8-TSSOP, 8-MSOP form factor with 0.118" (3.00mm) width
• Mounting Type: Surface Mount
• Supply Voltage Range: Minimum 2.4V to 5.5V maximum (or compatible superset)
• Operating Temperature: -40°C to 85°C minimum coverage

Identified Substitute Parts:

1. MAX4237AEUA+T (Analog Devices Inc./Maxim Integrated) — Direct equivalent with identical electrical specifications and Active product status
2. TLV4110IDGNR (Texas Instruments) — Manufacturer-recommended substitute with compatible package and electrical performance envelope

Parameter Comparison

Engineering Selection Recommendations

MAX4237AEUA+T Selection: The MAX4237AEUA+T is the primary substitute for the obsolete MAX4237AEUA-T. This part maintains identical electrical specifications, package configuration, and compliance certifications (ROHS3, REACH Unaffected). The MAX4237AEUA+T carries Active product status, ensuring long-term availability and supply chain continuity. Selection of this part eliminates all electrical and mechanical compatibility concerns for direct replacement applications.

TLV4110IDGNR Selection: The TLV4110IDGNR from Texas Instruments is a manufacturer-recommended alternative for the MAX4237AEUA-T. This device shares the same general-purpose amplifier classification, rail-to-rail output configuration, and 8-TSSOP/8-MSOP package footprint. The TLV4110IDGNR provides extended operating temperature range (-40°C to 125°C) and higher output current capability (320 mA vs. 30 mA). The part carries Active product status and full compliance certifications. Selection of this part is appropriate for applications where the extended temperature range or increased output current are beneficial, provided circuit design accommodates the specified electrical parameter differences.

Compliance and Certification: All identified substitute parts maintain ROHS3 compliance and REACH Unaffected status, consistent with the original MAX4237AEUA-T. Moisture sensitivity level remains at MSL 1 (Unlimited) across all options.

Frequently Asked Questions (FAQ)

Q: Can MAX4237AEUA+T directly replace MAX4237AEUA-T without circuit modification?

A: Yes. The MAX4237AEUA+T is electrically and mechanically identical to the MAX4237AEUA-T. All electrical parameters, package dimensions, and pin configurations are equivalent. Direct substitution is supported without circuit redesign.

Q: What are the key differences between MAX4237AEUA+T and TLV4110IDGNR?

A: The MAX4237AEUA+T maintains identical specifications to the original MAX4237AEUA-T. The TLV4110IDGNR differs in the following parameters: Slew Rate (1.57 V/µs vs. 1.3 V/µs), Gain Bandwidth Product (2.7 MHz vs. 7.5 MHz), Input Bias Current (0.3 pA vs. 1 pA), Input Offset Voltage (175 µV vs. 5 µV), Supply Current (700 µA vs. 350 µA), Output Current (320 mA vs. 30 mA), and Operating Temperature Range (-40°C to 125°C vs. -40°C to 85°C).

Q: Is the TLV4110IDGNR suitable for applications requiring the original MAX4237AEUA-T specifications?

A: The TLV4110IDGNR is suitable for applications where the electrical parameter differences are acceptable. The lower Gain Bandwidth Product (2.7 MHz vs. 7.5 MHz) and higher Input Offset Voltage (175 µV vs. 5 µV) represent the most significant deviations. Applications sensitive to these parameters require circuit evaluation before substitution.

Q: Are all substitute parts available in the same package configuration?

A: Yes. All identified substitute parts use the 8-TSSOP/8-MSOP package with 0.118" (3.00mm) width. The TLV4110IDGNR includes an exposed pad variant. PCB footprint compatibility is maintained across all options.

Q: What is the supply voltage compatibility across all parts?

A: The MAX4237AEUA-T and MAX4237AEUA+T operate from 2.4V to 5.5V. The TLV4110IDGNR operates from 2.5V to 6V. Applications using supply voltages between 2.5V and 5.5V are compatible with all three parts. Applications using 2.4V supply voltage require the MAX4237AEUA+T or MAX4237AEUA-T.

Q: Are there any compliance or certification differences between the substitute parts?

A: No. All identified substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity level. Compliance certifications are equivalent across all options.
