Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX526DENG are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution validity:

• 12-bit resolution with 4 independent DAC channels
• Parallel data interface architecture
• External reference input capability
• R-2R converter architecture
• Buffered voltage output configuration
• 3µs typical settling time performance
• ±1 LSB maximum INL/DNL specification
• 24-DIP through-hole package format
• Operating temperature range -40°C to 85°C
• Dual supply voltage requirement (10.8V ~ 16.5V, -5V)

Only parts meeting all these parameters are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The MAX526DENG+ serves as the direct substitute for the MAX526DENG. Both parts maintain identical electrical specifications and mechanical packaging. The primary distinction is product lifecycle status: the MAX526DENG is obsolete while the MAX526DENG+ is active production.

For new designs and ongoing production support, the MAX526DENG+ is the appropriate selection. This part carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. The MAX526DENG+ maintains full backward compatibility with existing MAX526DENG circuit implementations without requiring design modifications.

Frequently Asked Questions (FAQ)

Q: Can MAX526DENG+ directly replace MAX526DENG in existing designs?

A: Yes. The MAX526DENG+ is electrically and mechanically identical to the MAX526DENG. No circuit modifications are required for substitution. Both parts feature identical 12-bit DAC architecture, settling time, output buffering, and 24-DIP through-hole packaging.

Q: What is the primary difference between MAX526DENG and MAX526DENG+?

A: Product status and compliance certification. The MAX526DENG is obsolete, while MAX526DENG+ is active production. The MAX526DENG+ carries ROHS3 compliance; the MAX526DENG is RoHS non-compliant.

Q: Are there packaging differences between these parts?

A: No. Both parts use 24-DIP (0.300", 7.62mm) through-hole packaging. The MAX526DENG+ is supplied in tube packaging, while the MAX526DENG packaging specification was not provided.

Q: What supply voltage requirements apply to both parts?

A: Both require dual analog supply: 10.8V to 16.5V and -5V. Digital supply voltage specification was not provided in the component data.

Q: Do these parts require external reference configuration?

A: Yes. Both MAX526DENG and MAX526DENG+ utilize external reference input. Reference voltage specification must be determined from application requirements and circuit design parameters.
