AD7111KNZ Equivalent & Substitute Parts

Part Overview

The AD7111KNZ is a 17-bit digital-to-analog converter manufactured by Analog Devices Inc., designed for data acquisition applications requiring high-resolution current output. This component features a single D/A converter with R-2R architecture, parallel data interface, and unbuffered current output. The part operates with 5V analog and digital supply voltages across a 0°C to 70°C temperature range and is housed in a 16-DIP package for through-hole mounting.

The AD7111KNZ is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality in legacy designs, support production continuity, and enable component sourcing when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution analysis for the AD7111KNZ is constrained by the limited technical overlap between the main part and the provided substitute candidate. The AD7111KNZ is a dedicated 17-bit digital-to-analog converter with parallel data interface and current output architecture. The listed substitute, ADA4610-1ARZ, is a J-FET operational amplifier with rail-to-rail output characteristics.

These components operate in fundamentally different functional domains. The AD7111KNZ performs digital-to-analog conversion with fixed resolution and architecture, while the ADA4610-1ARZ is a general-purpose amplifier. Direct functional substitution is not supported by the provided parameters. Any application requiring the AD7111KNZ's specific D/A conversion capability cannot be satisfied by an operational amplifier alone.

Substitution consideration is limited to scenarios where the ADA4610-1ARZ may serve as a supporting component in a redesigned signal conditioning circuit, not as a direct replacement for the converter function itself.

Parameter Comparison

Engineering Selection Recommendations

The ADA4610-1ARZ cannot serve as a direct functional replacement for the AD7111KNZ due to fundamental architectural differences. The AD7111KNZ is a dedicated D/A converter; the ADA4610-1ARZ is an operational amplifier. These components perform distinct functions within signal processing chains.

Both components are manufactured by Analog Devices Inc. and share identical export classification (EAR99) and moisture sensitivity ratings. The ADA4610-1ARZ is currently in active production status, whereas the AD7111KNZ is obsolete.

For applications requiring 17-bit D/A conversion with parallel interface and current output, alternative D/A converter architectures from active product lines must be evaluated. The ADA4610-1ARZ may be considered only as a supporting component in a redesigned analog signal conditioning stage, not as a converter replacement.

Frequently Asked Questions (FAQ)

Q: Can the ADA4610-1ARZ directly replace the AD7111KNZ in an existing circuit?

A: No. The AD7111KNZ is a 17-bit digital-to-analog converter with parallel data interface. The ADA4610-1ARZ is an operational amplifier. These components serve different functions and cannot be directly substituted.

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

A: The AD7111KNZ converts digital parallel data to analog current output using R-2R architecture. The ADA4610-1ARZ amplifies analog signals with J-FET input stage and rail-to-rail output. No functional overlap exists for direct substitution.

Q: Are there packaging compatibility considerations?

A: Yes. The AD7111KNZ uses through-hole 16-DIP packaging (0.300", 7.62mm). The ADA4610-1ARZ uses surface-mount 8-SOIC packaging (0.154", 3.90mm Width). Board layout and assembly processes differ significantly.

Q: What supply voltage ranges do these components require?

A: The AD7111KNZ requires fixed 5V analog and digital supplies. The ADA4610-1ARZ operates across 9V to 30V supply span. Supply architecture redesign would be necessary if component substitution were considered.

Q: What is the operating temperature range for each component?

A: The AD7111KNZ operates from 0°C to 70°C. The ADA4610-1ARZ operates from -40°C to 125°C, providing wider temperature coverage.

Q: Are both components RoHS compliant?

A: The AD7111KNZ compliance status is not specified in the provided parameters. The ADA4610-1ARZ is ROHS3 compliant and REACH unaffected.
