• Output configuration: Voltage - Unbuffered
• Reference input: External reference type
• Supply voltages: 5V analog and digital
• Accuracy: ±1 LSB INL/DNL maximum
• Conversion architecture: R-2R topology
• Settling time: 2µs typical
• Package form factor: 20-SSOP surface mount
• Operating temperature range: 0°C ~ 70°C

Parameter Comparison

Engineering Selection Recommendations

The MAX520ACAP+ is a direct functional equivalent to the MAX520ACAP with identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the MAX520ACAP is obsolete while the MAX520ACAP+ is active production.

The MAX520ACAP+ offers improved compliance status, meeting ROHS3 requirements compared to the non-compliant status of the original part. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

For new designs or applications requiring component replacement, the MAX520ACAP+ is the appropriate selection due to active production status and regulatory compliance. Existing designs using the MAX520ACAP can transition to the MAX520ACAP+ without circuit modification, as all functional and physical parameters remain identical.
