Substitute Part Grouping Explanation

Substitution for the MAX158ACPI+ is determined by strict equivalence across the following critical parameters:

• Resolution: 8 bits
• Sampling rate: 400k samples per second
• Input configuration: 8 single-ended channels
• Data interface: Parallel output
• Converter architecture: Flash
• Supply voltages: 5V analog and digital
• Package: 28-DIP through-hole
• Operating temperature range: 0°C to 70°C

The MAX158BCPI+ meets all these electrical and mechanical requirements and serves as a direct parametric equivalent. Both parts share identical base product number (MAX158) and differ only in product status classification.
