Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4376HASA is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Slew Rate: 10 V/µs
• -3dB Bandwidth: 1.2 MHz
• Current - Input Bias: 800 µA
• Current - Supply: 1 mA
• Voltage - Supply Span: 3 V to 28 V
• Operating Temperature Range: -40°C to 125°C

Mechanical & Package Specifications:

• Mounting Type: Surface Mount
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Number of Circuits: 1

Compliance & Environmental:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must match all electrical parameters, maintain identical package geometry, and satisfy the same compliance requirements. Packaging format (Tube vs. other configurations) does not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The MAX4376HASA+ is the direct functional equivalent of the MAX4376HASA. Both parts share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status: the MAX4376HASA is classified as obsolete, while the MAX4376HASA+ maintains active status with Analog Devices Inc./Maxim Integrated.

For new designs or ongoing procurement requirements, the MAX4376HASA+ is the appropriate selection. This part maintains full ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental standards. The active product status of the MAX4376HASA+ provides assurance of continued availability and technical support from the manufacturer.

Existing designs utilizing the MAX4376HASA can transition to the MAX4376HASA+ without circuit modification, as all electrical and mechanical parameters are identical. Pin configuration, signal characteristics, and supply requirements remain unchanged.
