Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4372HESA is determined by strict equivalence across all electrical and mechanical parameters. The substitute relationship is based on the following criteria:

Electrical Parameter Equivalence:

• Amplifier type classification (Current Sense)
• Number of circuits (1)
• Bandwidth specification (-3dB Bandwidth: 110 kHz)
• Input bias current (2 µA)
• Input offset voltage (300 µV)
• Supply current (30 µA)
• Supply voltage range (2.7 V to 28 V)
• Operating temperature range (-40°C to 85°C)

Mechanical Parameter Equivalence:

• Mounting type (Surface Mount)
• Package configuration (8-SOIC with 0.154" / 3.90mm width)
• Supplier device package designation (8-SOIC)

The MAX4372HESA+ qualifies as a direct substitute based on identical electrical specifications and mechanical packaging. The primary distinction between these parts is product status and packaging format, not functional performance.

Engineering Selection Recommendations

MAX4372HESA+ as Primary Substitute:

The MAX4372HESA+ is the direct functional equivalent of the MAX4372HESA. All electrical parameters, mechanical specifications, and package configurations are identical. The MAX4372HESA+ is classified as active product status, ensuring continued manufacturer support and availability. Additionally, the MAX4372HESA+ carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

For new designs, production continuity, or system upgrades, the MAX4372HESA+ is the appropriate selection. The transition from the obsolete MAX4372HESA to the MAX4372HESA+ requires no circuit redesign, PCB layout modification, or firmware adjustment, as all functional and mechanical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the MAX4372HESA+ directly replace the MAX4372HESA in existing designs?

A: Yes. The MAX4372HESA+ is electrically and mechanically identical to the MAX4372HESA. All electrical parameters, including bandwidth, input bias current, input offset voltage, supply current, and operating temperature range are equivalent. The 8-SOIC package configuration and pinout are identical, enabling direct substitution without circuit modification.

Q: What is the primary difference between MAX4372HESA and MAX4372HESA+?

A: The primary differences are product status and regulatory compliance. The MAX4372HESA is classified as obsolete, while the MAX4372HESA+ is active. The MAX4372HESA+ is ROHS3 compliant, whereas the MAX4372HESA is RoHS non-compliant. Functionally and electrically, both parts are equivalent.

Q: Are there packaging format differences between these parts?

A: Both parts use the 8-SOIC surface mount package with identical dimensions (0.154" / 3.90mm width). The primary packaging distinction is that the MAX4372HESA+ is supplied in tube packaging format, while the MAX4372HESA packaging format is not specified in the component data.

Q: Why should I select the MAX4372HESA+ over the MAX4372HESA?

A: The MAX4372HESA+ should be selected for new designs and production applications because it is active product status with manufacturer support and ROHS3 compliance. The MAX4372HESA is obsolete, which may result in supply constraints and lack of ongoing technical support.

Q: Are the electrical specifications identical between both parts?

A: Yes. Both parts share identical electrical specifications: 110 kHz bandwidth, 2 µA input bias current, 300 µV input offset voltage, 30 µA supply current, 2.7 V to 28 V supply voltage range, and -40°C to 85°C operating temperature range.

Q: What is the base product number for these components?

A: The base product number is MAX4372. Both the MAX4372HESA and MAX4372HESA+ are variants of this base product line.
