Key Parameters

Substitute Part Grouping Explanation

Substitution is determined exclusively by matching these parameters: amplifier type, circuit count, output configuration, package/case, mounting type, voltage supply span, and compliance. All listed substitutes are dual amplifiers (2 circuits), feature rail-to-rail output, and share the 8-SOIC surface mount package. Regulatory compliance, similar supply voltage range, and product status are also considered to ensure seamless compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed (AD8028ARZ-REEL7, TLV2432AQD, TLV2432QDRG4Q1) are active, ROHS3 compliant, REACH unaffected, and maintain ECCN EAR99 export classification. The packaging type for all options is 8-SOIC surface mount, consistent with the ALD2731ASAL. Differences in product status for TLV2432AQD and TLV2432QDRG4Q1 are indicated with "Last Time Buy"; for long-term supply planning, consider only active and in-production alternatives.
