AD7247JN Equivalent & Substitute Parts

Part Overview

The AD7247JN is a 12-bit Digital to Analog Converter (DAC) manufactured by Analog Devices Inc., featuring dual D/A converters with voltage-buffered output and parallel data interface. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs. The AD7247JN operates with external or internal reference types and requires dual supply voltages (±15V analog, 15V digital), making substitute selection dependent on maintaining these electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD7247JN are identified based on strict electrical and mechanical parameter matching. The critical parameters determining substitution eligibility are:

• 12-bit resolution with dual D/A converters
• Voltage-buffered output configuration
• Parallel data interface
• External and internal reference capability
• ±15V analog and 15V digital supply requirements
• R-2R architecture
• 24-DIP through-hole package format
• Operating temperature range of -40°C to 85°C
• Settling time of 10µs
• INL/DNL specifications of ±1 LSB (Max) and ±0.9 LSB (Max)

The AD7247JNZ qualifies as a direct substitute, maintaining identical electrical specifications and package configuration while differing only in product status (Active vs. Obsolete) and packaging format (Tube vs. unspecified for the original).

Parameter Comparison

Engineering Selection Recommendations

The AD7247JNZ is the direct equivalent for the obsolete AD7247JN. Both components share identical electrical characteristics, resolution, converter count, output configuration, and package specifications. The primary distinction is product status: AD7247JNZ maintains Active status with current manufacturing support, whereas AD7247JN is classified as Obsolete.

For new designs or system replacements, AD7247JNZ is the appropriate selection due to its Active product status and ROHS3 compliance certification. The AD7247JNZ provides continuity of supply and regulatory compliance assurance that the obsolete AD7247JN cannot guarantee.

Frequently Asked Questions (FAQ)

Q: Can AD7247JNZ directly replace AD7247JN in existing designs?

A: Yes. The AD7247JNZ maintains identical electrical specifications, resolution (12-bit), dual converter configuration, output type (voltage-buffered), data interface (parallel), supply requirements (±15V analog, 15V digital), and 24-DIP through-hole package format. No circuit modifications are required.

Q: What is the primary reason to transition from AD7247JN to AD7247JNZ?

A: The AD7247JN is classified as Obsolete, indicating discontinued manufacturing and limited availability. The AD7247JNZ is Active status with ongoing production support and regulatory compliance certifications (ROHS3, REACH Unaffected).

Q: Are there packaging differences between these parts?

A: Both components use 24-DIP (0.300", 7.62mm) through-hole packages. The AD7247JNZ is supplied in Tube packaging format, which is standard for active production components.

Q: Do the settling time and accuracy specifications differ?

A: No. Both parts specify 10µs settling time and identical INL/DNL performance of ±1 LSB (Max) and ±0.9 LSB (Max), ensuring equivalent analog performance in applications.

Q: What supply voltages are required for operation?

A: Both AD7247JN and AD7247JNZ require ±15V for analog supply and 15V for digital supply. Verify your power distribution design accommodates these dual-supply requirements.
