Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD7543JPZ is determined by strict equivalence across the following critical parameters:

• Resolution & Architecture: 12-bit resolution with R-2R architecture
• Functional Interface: Serial data interface with external voltage reference
• Output Characteristics: Current output, unbuffered, with differential capability
• Electrical Specifications: 5V analog and digital supply voltages; 2µs settling time
• Physical Form Factor: 20-LCC (J-Lead) package in 20-PLCC (9x9) configuration
• Environmental Rating: -40°C to 85°C operating temperature range
• Mounting Standard: Surface mount technology

The AD7543KPZ qualifies as a direct substitute based on matching all critical parameters while offering improved linearity specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The AD7543KPZ is the direct substitute for the obsolete AD7543JPZ. Both devices share identical functional specifications, electrical performance parameters, and physical packaging. The AD7543KPZ offers the following advantages:

• Active Product Status: Currently manufactured and supported by Analog Devices Inc., ensuring long-term availability and supply chain reliability
• Improved Linearity: INL/DNL specifications of ±0.5/±1 LSB (Max) compared to ±1/±2 LSB (Max) on the original part, providing enhanced accuracy
• Regulatory Compliance: ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements
• Packaging Availability: Supplied in tube packaging, facilitating standard procurement and handling procedures

Pin-to-pin and functional compatibility is maintained across all critical parameters. No circuit redesign is required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the AD7543KPZ directly replace the AD7543JPZ without circuit modifications?

A: Yes. The AD7543KPZ is functionally and pin-compatible with the AD7543JPZ. Both devices feature identical 12-bit resolution, serial interface, external reference configuration, 5V supply requirements, and 20-PLCC (9x9) package geometry. No circuit redesign is necessary.

Q: What are the key differences between these two parts?

A: The primary differences are product status and linearity performance. The AD7543JPZ is obsolete, while the AD7543KPZ is active. The AD7543KPZ provides improved INL/DNL specifications (±0.5/±1 LSB vs. ±1/±2 LSB) and includes ROHS3 compliance certification.

Q: Are there any supply voltage or operating temperature restrictions when substituting?

A: No. Both parts operate identically across the -40°C to 85°C temperature range and require 5V analog and digital supply voltages. Operating conditions remain unchanged.

Q: Does the improved linearity of the AD7543KPZ affect system compatibility?

A: No. The improved linearity of the AD7543KPZ is a performance enhancement that maintains backward compatibility. Systems designed for the AD7543JPZ specifications will operate correctly with the AD7543KPZ.

Q: What packaging formats are available for the substitute part?

A: The AD7543KPZ is supplied in tube packaging, which is standard for high-volume procurement and automated assembly processes.

Q: Are there regulatory or compliance considerations for the substitute part?

A: The AD7543KPZ is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The original AD7543JPZ compliance status is not specified in available documentation.
