AD8223AR-RL Equivalent & Substitute Parts

Part Overview

The AD8223AR-RL is an instrumentation amplifier manufactured by Analog Devices Inc., featuring a single circuit with rail-to-rail output capability in an 8-SOIC surface mount package. This device is classified as obsolete, making identification of equivalent and substitute parts essential for design continuity and procurement planning. The AD8223AR-RL operates across a 3V to 24V supply range with low input offset voltage and minimal input bias current, suitable for precision measurement and signal conditioning applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8223AR-RL is determined by compatibility across the following critical parameters: amplifier type classification, number of circuits, output type, package form factor, mounting technology, and electrical operating specifications including supply voltage range and temperature range.

Direct Equivalent Substitution is based on identical or functionally equivalent specifications across all key parameters. The AD8223ARZ-RL maintains the same instrumentation amplifier architecture, single circuit configuration, rail-to-rail output, identical electrical performance characteristics, and 8-SOIC package footprint. The primary distinction is product status (Active versus Obsolete) and packaging format (Cut Tape versus Reel).

Similar Substitution involves devices that share the same package form factor and mounting technology but differ in amplifier type, circuit count, and electrical performance. The ADA4622-2ARZ-RL is a J-FET amplifier with dual circuits, higher bandwidth capability, and extended supply voltage range. This device requires circuit design evaluation due to architectural differences and performance parameter variations.

Engineering Selection Recommendations

For Direct Replacement: The AD8223ARZ-RL is the appropriate selection when maintaining identical electrical performance and functional characteristics is required. This part is currently in active production status with ROHS3 compliance certification and REACH unaffected status, providing long-term supply chain stability. The AD8223ARZ-RL is available in Cut Tape packaging format with 6021 pieces in current inventory.

For Performance-Enhanced Applications: The ADA4622-2ARZ-RL offers significantly improved electrical performance characteristics including 76.7× higher slew rate (23 V/µs versus 0.3 V/µs), 77.5× higher bandwidth (15.5 MHz versus 200 kHz), and substantially lower input bias current (2 pA versus 12 nA). This device operates across an extended supply voltage range (5V to 30V minimum/maximum) and temperature range (-40°C to 125°C). However, the ADA4622-2ARZ-RL is a dual-circuit J-FET amplifier architecture, requiring circuit design modifications for single-channel applications. This part is active production status with ROHS3 compliance and REACH unaffected status, available in Tape & Reel packaging with 7700 pieces in current inventory.

Compliance Considerations: Both substitute parts maintain identical moisture sensitivity classification (MSL 1 - Unlimited) and ECCN/HTSUS coding as the original device. The AD8223ARZ-RL provides direct compliance continuity. The ADA4622-2ARZ-RL extends the operating temperature range, which may provide additional design margin in temperature-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the AD8223ARZ-RL be used as a direct drop-in replacement for the AD8223AR-RL?

A: Yes. The AD8223ARZ-RL maintains identical electrical specifications, amplifier type (instrumentation), circuit count (1), output type (rail-to-rail), and 8-SOIC package footprint. The primary differences are product status (Active versus Obsolete) and packaging format (Cut Tape versus Reel). No circuit modifications are required.

Q: What are the key differences between the AD8223AR-RL and the ADA4622-2ARZ-RL?

A: The ADA4622-2ARZ-RL differs in amplifier type (J-FET versus Instrumentation), circuit count (2 versus 1), slew rate (23 V/µs versus 0.3 V/µs), bandwidth (15.5 MHz versus 200 kHz), input bias current (2 pA versus 12 nA), and minimum supply voltage (5V versus 3V). Both devices share the same 8-SOIC package and rail-to-rail output type.

Q: Is the ADA4622-2ARZ-RL suitable for applications requiring the AD8223AR-RL specifications?

A: The ADA4622-2ARZ-RL can be used in applications where the enhanced performance characteristics (higher bandwidth, lower input bias current, faster slew rate) are beneficial or acceptable. However, the dual-circuit architecture and different amplifier type require circuit design evaluation. The minimum supply voltage requirement of 5V (versus 3V for the AD8223AR-RL) must be verified against system power supply specifications.

Q: Are there packaging compatibility concerns when substituting these parts?

A: All three parts (AD8223AR-RL, AD8223ARZ-RL, and ADA4622-2ARZ-RL) use identical 8-SOIC package form factors with 0.154" width and 3.90mm dimensions. PCB footprints and reflow soldering profiles are compatible. Packaging format differences (Cut Tape, Reel, Tape & Reel) affect procurement and handling but not electrical or mechanical compatibility.

Q: What is the inventory status for substitute parts?

A: The AD8223ARZ-RL has 6021 pieces in current inventory. The ADA4622-2ARZ-RL has 7700 pieces in current inventory. The original AD8223AR-RL has 1044 pieces in inventory but is classified as obsolete.

Q: Do the substitute parts meet the same compliance requirements?

A: Both substitute parts maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 1 - Unlimited), ECCN (EAR99), and HTSUS (8542.33.0001) classifications are identical across all three parts.
