Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4080FASA-T is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Amplifier type (Current Sense), number of circuits (1), bandwidth (250 kHz), input bias current (5 µA), input offset voltage (100 µV), supply current (75 µA), and supply voltage range (4.5 V to 76 V).

Thermal Parameters: Operating temperature range (-40°C to 125°C) must be maintained.

Mechanical Parameters: Package type (8-SOIC with 0.154" / 3.90mm width) and surface mount mounting type are mandatory for physical and electrical compatibility.

Compliance Parameters: RoHS3 compliance and MSL Level 1 rating must be preserved.

The substitute part MAX4080FASA+T meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations
