Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4376FASA is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Amplifier Type: Current Sense
• Number of Circuits: 1
• Slew Rate: 10 V/µs
• -3dB Bandwidth: 1.7 MHz
• Current - Input Bias: 800 µA
• Current - Supply: 1 mA

Electrical Parameters:

• Voltage - Supply Span (Min): 3 V
• Voltage - Supply Span (Max): 28 V
• Operating Temperature Range: -40°C to 125°C

Physical & Compliance Parameters:

• Mounting Type: Surface Mount
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts must match all parameters listed above. Packaging format (Tube vs. other configurations) does not affect electrical or mechanical compatibility and is therefore not a substitution barrier.
