Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX547BCMH+ are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

• Resolution: 13-bit conversion
• Channel Count: 8 independent DAC channels
• Output Configuration: Voltage-buffered topology
• Interface: Parallel data input
• Reference: External reference requirement
• Supply Voltage: ±5V analog supply
• Accuracy: INL/DNL specifications of ±0.5, ±1 (Max) LSB
• Architecture: R-2R ladder network
• Temperature Range: 0°C ~ 70°C operation
• Package: 44-MQFP (10x10) surface-mount form factor
• Compliance: ROHS3 and REACH certifications

All identified substitute parts maintain identical electrical performance characteristics and physical packaging specifications, ensuring direct functional replacement without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can MAX547ACMH+ be used as a direct replacement for MAX547BCMH+?

A: Yes. Both parts maintain identical electrical parameters including 13-bit resolution, 8 DAC channels, 5µs settling time, ±5V supply voltage, and ±0.5/±1 LSB accuracy specifications. The 44-MQFP (10x10) surface-mount package is identical, enabling direct PCB substitution.

Q: What is the difference between MAX547ACMH+ and MAX547ACMH+D?

A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. The suffix designation reflects internal manufacturing or qualification differences that do not affect functional performance or pin compatibility.

Q: Are all substitute parts ROHS3 and REACH compliant?

A: Yes. MAX547BCMH+, MAX547ACMH+, and MAX547ACMH+D are all ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for restricted substance use.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All three parts carry MSL 3 rating with a 168-hour floor life. This specification defines handling and storage requirements to prevent moisture absorption that could compromise solder joint reliability during reflow assembly.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All three parts share identical pin configurations, electrical performance, and package dimensions. No circuit redesign or PCB layout modification is required for substitution.

Q: What is the operating temperature range for these DAC devices?

A: The operating temperature range is 0°C to 70°C for all three parts. Applications requiring extended temperature operation require alternative device selection.
