MAX547ACMH 13-Bit Digital to Analog Converter Equivalent & Substitute Parts

Part Overview

The MAX547ACMH is a 13-bit digital to analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring 8 independent voltage output channels. The device features an R-2R ladder architecture with external reference capability and operates from ±5V analog supply.

The MAX547ACMH is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently utilizing this component.

Substitute Part Grouping Explanation

Substitute parts for the MAX547ACMH are determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish substitutability:

Critical Parameters for Substitution:

• 13-bit resolution with 8 independent D/A converters
• Voltage-buffered output configuration
• 5µs typical settling time
• Parallel data interface with external reference
• ±5V analog supply voltage
• ±0.5, ±1 LSB INL/DNL specifications
• R-2R ladder architecture
• 0°C to 70°C operating temperature range
• 44-MQFP (10x10) surface mount package

All identified substitute parts maintain identical electrical performance and mechanical compatibility with the MAX547ACMH across these parameters. Substitutes differ only in product status (active vs. obsolete), packaging format (tube), and RoHS compliance certification status.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—MAX547ACMH+, MAX547ACMH+D, and MAX547BCMH+—provide direct functional equivalence to the obsolete MAX547ACMH across all electrical and mechanical specifications.

Product Status Consideration: The MAX547ACMH is obsolete, while MAX547ACMH+, MAX547ACMH+D, and MAX547BCMH+ are active products. Active status ensures ongoing manufacturer support, availability, and compliance with current industry standards.

Compliance Advantage: All substitute parts carry ROHS3 compliance certification, whereas the original MAX547ACMH is RoHS non-compliant. This distinction is significant for applications subject to environmental regulations or customer requirements mandating RoHS compliance.

Packaging and Availability: All substitutes are supplied in tube packaging format, supporting both prototype and production-volume applications. Current inventory levels across all three substitutes exceed 900 units, ensuring supply continuity.

Selection among the three active substitutes should be based on internal part numbering conventions, existing supply chain relationships, and specific packaging preferences, as all three maintain identical electrical performance and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX547ACMH+ directly replace MAX547ACMH in existing designs?

A: Yes. MAX547ACMH+ maintains identical electrical specifications, pin configuration, and 44-MQFP (10x10) package geometry. No circuit modifications are required for direct substitution.

Q: What is the difference between MAX547ACMH+, MAX547ACMH+D, and MAX547BCMH+?

A: All three parts are parametrically equivalent across 13-bit resolution, 8-channel DAC configuration, ±5V supply, 5µs settling time, and 44-MQFP packaging. Differences exist only in product status (all active), RoHS compliance (all ROHS3 compliant), and internal manufacturer designations. The suffix variations (+, +D) reflect packaging or manufacturing process distinctions that do not affect electrical performance or mechanical compatibility.

Q: Why is the original MAX547ACMH classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of this specific part number. Active substitute variants ensure continued access to equivalent functionality through current production lines.

Q: Are there any thermal or environmental performance differences between the substitutes?

A: No. All parts operate across the identical 0°C to 70°C temperature range and maintain the same MSL 3 (168 Hours) moisture sensitivity rating. Thermal and environmental performance characteristics are equivalent.

Q: Does RoHS3 compliance affect electrical performance?

A: No. RoHS3 compliance addresses material composition and environmental standards only. Electrical specifications, settling time, linearity, and output characteristics remain unchanged between RoHS non-compliant and ROHS3 compliant variants.

Q: Can these parts be used interchangeably in production?

A: Yes. All substitute parts meet identical electrical and mechanical requirements. Production designs can utilize any of the three active substitutes without design revision or performance impact.
