MAX7645BCPP+ Equivalent & Substitute Parts

Part Overview

The MAX7645BCPP+ is a 12-bit CMOS buffered digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. This component is classified as data acquisition integrated circuitry and is packaged in a 20-pin DIP format suitable for through-hole mounting applications. The part maintains active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Given the active market availability of functionally equivalent alternatives from the same manufacturer family, substitute parts are available to support design flexibility, inventory optimization, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX7645BCPP+ are qualified based on strict electrical and mechanical parameter alignment within the 12-bit DAC category. All substitute candidates share the following critical parameters with the main part:

• 12-bit resolution
• Single D/A converter configuration
• 20-pin DIP package (0.300", 7.62mm)
• Through-hole mounting compatibility
• Parallel data interface
• Current-unbuffered output topology
• External reference requirement
• Dual supply voltage range (5V ~ 15V for both analog and digital)
• R-2R ladder architecture
• 0°C ~ 70°C operating temperature range
• ROHS3 compliance
• MSL 1 rating
• Active product status

Substitute parts are differentiated by settling time and INL/DNL (integral nonlinearity/differential nonlinearity) specifications, which represent performance grade variations within the AD7545 base product family. These variations allow selection based on application-specific accuracy requirements while maintaining full functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full ROHS3 compliance, ensuring regulatory alignment with the original MAX7645BCPP+. Selection among substitute options is determined by accuracy grade requirements:

AD7545GLNZ provides the highest accuracy specification with INL/DNL of ±0.5 LSB (Max) and ±1 LSB (Max), suitable for applications requiring precision analog output with minimal linearity error.

AD7545KNZ offers balanced accuracy with INL/DNL of ±1 LSB (Max) and ±1 LSB (Max), appropriate for general-purpose data acquisition applications with moderate accuracy demands.

AD7545JNZ delivers standard-grade accuracy with INL/DNL of ±2 LSB (Max) and ±4 LSB (Max), suitable for cost-optimized designs where relaxed linearity tolerances are acceptable.

All substitute parts share identical settling time (2µs), supply voltage ranges, package geometry, and thermal operating range with the main part, ensuring direct functional replacement without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Are these substitute parts pin-compatible with the MAX7645BCPP+?

A: Yes. All substitute parts utilize the 20-pin DIP package format (0.300", 7.62mm) with through-hole mounting, ensuring identical PCB footprint and pin assignment compatibility.

Q: What is the primary difference between the substitute options?

A: The substitute parts differ in accuracy specifications (INL/DNL values). AD7545GLNZ provides the tightest linearity tolerance, AD7545KNZ offers mid-range accuracy, and AD7545JNZ provides standard-grade performance. All other electrical and mechanical parameters remain identical.

Q: Can I substitute these parts without modifying my circuit design?

A: Yes. All substitute parts maintain identical supply voltage requirements (5V ~ 15V for both analog and digital), external reference architecture, parallel data interface, and R-2R ladder topology. No circuit modifications are required for functional substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification with MSL 1 (unlimited moisture sensitivity rating), matching the environmental and regulatory status of the MAX7645BCPP+.

Q: What is the settling time specification for these DAC parts?

A: All substitute parts specify 2µs settling time. The MAX7645BCPP+ settling time is not provided in the available documentation.

Q: Which substitute part should I select for my application?

A: Selection depends on your accuracy requirements. For applications requiring high precision analog output, select AD7545GLNZ. For general-purpose applications with moderate accuracy needs, select AD7545KNZ. For cost-optimized designs with relaxed linearity requirements, select AD7545JNZ.
