Engineering Selection Recommendations

MAX4080TASA+ as Direct Substitute:

The MAX4080TASA+ is a direct electrical and mechanical equivalent to the MAX4080TASA. All critical electrical parameters, including bandwidth, bias current, input offset voltage, supply current, and supply voltage range, are identical. Both parts utilize the same 8-SOIC package with identical pin configuration and mechanical dimensions.

The primary distinction between these parts is product status: the MAX4080TASA is classified as obsolete, while the MAX4080TASA+ is active. For new designs or production continuity, the MAX4080TASA+ is the appropriate selection. Both parts maintain identical RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings.

The MAX4080TASA+ is supplied in Tube packaging, whereas the original part packaging specification is not provided. This packaging difference does not affect electrical performance or circuit compatibility.
