Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX9043AEUB is determined by strict equivalence across the following critical parameters:

• Dual-channel comparator architecture (2 elements)
• Output configuration: CMOS, push-pull, rail-to-rail, TTL-compatible
• Supply voltage range: 2.5V ~ 5.5V
• Input offset voltage: 5mV @ 5V maximum
• Input bias current: 1pA @ 5V maximum
• Output current capability: 8mA typical
• Quiescent current: 85µA maximum
• Common-mode rejection ratio and power supply rejection ratio: 80dB each
• Propagation delay: 450ns maximum
• Hysteresis: ±3mV
• Operating temperature range: -40°C ~ 85°C
• Package type: 10-TFSOP / 10-MSOP surface mount
• Compliance: ROHS3, MSL Level 1

The MAX9043AEUB+ meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The MAX9043AEUB+ is the direct functional equivalent of the MAX9043AEUB. Both parts share identical electrical specifications, package configurations, and compliance certifications. The primary distinction is product status: the original MAX9043AEUB is obsolete, while the MAX9043AEUB+ maintains active production status.

For new designs or ongoing production requiring the MAX9043 comparator family, the MAX9043AEUB+ is the appropriate selection. Both parts are ROHS3 compliant and carry MSL Level 1 rating, indicating no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)
