Engineering Selection Recommendations
The MAX507AENG+ is the direct functional equivalent of the MAX507AENG. Both components share identical electrical specifications, performance characteristics, and physical packaging. The primary distinction is product lifecycle status and regulatory compliance.
The MAX507AENG is classified as obsolete, presenting supply chain risk for new production or long-term maintenance. The MAX507AENG+ maintains active product status with current manufacturing support and improved regulatory compliance (ROHS3 Compliant versus RoHS non-compliant). Both components are REACH Unaffected and classified under ECCN EAR99.
For applications requiring the 12-bit DAC functionality specified by the MAX507AENG, the MAX507AENG+ is the appropriate selection, offering equivalent performance with enhanced availability and compliance posture.
Frequently Asked Questions (FAQ)
Q: Can MAX507AENG+ directly replace MAX507AENG in existing designs?
A: Yes. The MAX507AENG+ is electrically and mechanically equivalent. Both components feature identical 12-bit resolution, 5µs settling time, R-2R architecture, parallel interface, and 24-DIP through-hole packaging. No circuit modifications are required for substitution.
Q: What is the primary reason to transition from MAX507AENG to MAX507AENG+?
A: The MAX507AENG is obsolete with no active manufacturing. The MAX507AENG+ is an active product with current supply availability. Additionally, MAX507AENG+ meets ROHS3 compliance requirements, whereas MAX507AENG is RoHS non-compliant.
Q: Are the supply voltage requirements identical between these parts?
A: Yes. Both components require identical dual analog supply (±11.4V ~ 15.75V) and digital supply (11.4V ~ 15.75V) voltages. Power supply design modifications are not necessary.
Q: Do both parts operate across the same temperature range?
A: Yes. Both MAX507AENG and MAX507AENG+ are specified for -40°C to 85°C operating temperature range.
Q: Is the 24-DIP package pinout identical?
A: Yes. Both components use the same 24-DIP (0.300", 7.62mm) through-hole package with identical pinout. PCB layouts require no modification.
Q: What is the difference in packaging between these parts?
A: The MAX507AENG packaging type is not specified in available data. The MAX507AENG+ is supplied in Tube packaging. Verify packaging requirements for your procurement and assembly processes.
