Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX518BESA is determined by strict equivalence across the following critical parameters:

• Resolution & Channel Count: 8-bit resolution with dual D/A converters (2 channels)
• Interface Protocol: I2C digital communication standard
• Output Configuration: Buffered voltage output with external reference capability
• Supply Voltage: Dual 5V supplies (analog and digital)
• Electrical Performance: Settling time of 6µs (Typ), INL/DNL specifications of ±1.5 LSB (Max) and ±1 LSB (Max)
• Package Compatibility: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Temperature Range: -40°C to 85°C operating specification

The MAX518BESA+ meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAX518BESA+ is the direct active equivalent for the obsolete MAX518BESA. Both components share identical electrical specifications, pin configurations, and functional characteristics across all critical parameters. The primary distinction is product lifecycle status and regulatory compliance.

The MAX518BESA+ is recommended for new designs and production continuity due to its active product status and ROHS3 compliance certification. The obsolete MAX518BESA should be replaced with MAX518BESA+ in existing designs requiring component replenishment or redesign cycles. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain full functional interchangeability within the specified operating parameters.

Frequently Asked Questions (FAQ)
