Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX1204AEAP+ is determined by strict equivalence across the following critical parameters:

• Resolution: 10-bit conversion capability
• Sampling Rate: 133 kSPS minimum performance
• Input Configuration: Support for 4 or 8 input channels with differential and single-ended modes
• Data Interface: SPI protocol compatibility
• Architecture: SAR-based conversion
• Supply Voltage Compatibility: ±5V and 5V operation for both analog and digital domains
• Operating Temperature: -40°C to 85°C range
• Package: 20-SSOP form factor with identical pinout and mechanical dimensions
• Compliance: ROHS3 compliance and MSL 1 rating

The MAX1204BEAP+ meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, package geometry, and functional characteristics, making them directly interchangeable at the component level.

Parameter Comparison
