Substitute Part Grouping Explanation

Substitution of the AD7828LNZ is determined by strict equivalence across the following critical parameters:

• Resolution: 8 bits
• Input configuration: 8 single-ended inputs
• Sampling rate: 50 kHz minimum
• Architecture: Flash ADC
• Data interface: Parallel output
• Supply voltages: 5V analog and digital
• Package: 28-DIP through-hole
• Reference input: External

The AD7828KNZ meets all electrical and mechanical specifications required for direct substitution. Both devices share identical base product architecture (AD7828 series), pin configuration, and functional performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AD7828KNZ is the direct substitute for the AD7828LNZ. Both components are electrically and mechanically identical across all specified parameters. The AD7828KNZ offers the advantage of active product status, ensuring continued availability and support from Analog Devices Inc.

The AD7828KNZ carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for new designs and production applications. Selection of the AD7828KNZ eliminates obsolescence risk associated with the AD7828LNZ while maintaining full functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AD7828KNZ directly replace the AD7828LNZ in existing designs?

A: Yes. Both parts are pin-compatible and functionally equivalent across all electrical and mechanical parameters. No circuit modifications are required for substitution.

Q: What is the difference between the AD7828LNZ and AD7828KNZ?

A: The primary difference is product status. The AD7828LNZ is obsolete, while the AD7828KNZ is active. The AD7828KNZ also includes ROHS3 compliance and REACH unaffected certification. All functional specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both devices use the 28-DIP (0.600", 15.24mm) package with identical through-hole mounting configuration and pin assignments.

Q: Does the AD7828KNZ meet current environmental standards?

A: Yes. The AD7828KNZ is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What supply voltages are required for the AD7828KNZ?

A: The AD7828KNZ requires 5V for both analog and digital supply inputs, identical to the AD7828LNZ.

Q: Is the sampling rate the same for both parts?

A: Yes. Both the AD7828LNZ and AD7828KNZ operate at 50 kHz sampling rate with 8-bit resolution and 8 single-ended input channels.
