Key Parameters

Substitute Part Grouping Explanation

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

Electrical Specifications:

• Amplifier type classification (Current Sense)
• Number of circuits (1)
• Slew rate (10V/µs)
• -3dB bandwidth (1.2 MHz)
• Input bias current (800 µA)
• Supply current (1 mA)
• Supply voltage range (3V to 28V minimum and maximum)
• Operating temperature range (-40°C to 125°C)

Mechanical & Environmental Specifications:

• Package type (8-SOIC)
• Physical dimensions (0.154", 3.90mm Width)
• Surface mount mounting type
• RoHS3 compliance
• Moisture sensitivity level (MSL 1)

The MAX4376HASA+T qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction between the main part and its substitute is the packaging format: the main part is supplied in individual packaging, while the substitute is supplied in Tape & Reel (TR) format. Both parts share the same base product number (MAX4376) and are manufactured by the same supplier.

Parameter Comparison

Engineering Selection Recommendations

The MAX4376HASA+T is the direct functional equivalent of the MAX4376HASA-T for all electrical and mechanical applications. Selection between these parts should be based on the following criteria:
