Substitute Part Grouping Explanation

Substitution eligibility for the MAX1680ESA is determined by strict equivalence across the following critical parameters:

• Topology: Charge Pump
• Output Configuration: Positive or Negative
• Output Type: Fixed
• Number of Outputs: 1
• Voltage - Input Range: 2V to 5.5V
• Voltage - Output: -Vin, 2Vin
• Current - Output: 125mA
• Switching Frequency: 125kHz, 250kHz
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Operating Temperature: -40°C ~ 85°C (TA)

The MAX1680ESA+ meets all substitution criteria as a direct equivalent part from the same manufacturer with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX1680ESA+ is the direct substitute for the MAX1680ESA. Both parts are electrically and mechanically identical across all functional parameters. The primary distinction is product lifecycle status and regulatory compliance.
