Engineering Selection Recommendations

AD8022ARZ - Primary Substitute

The AD8022ARZ is the recommended primary substitute for the TS613IDT. Both devices are voltage feedback amplifiers with dual-channel configuration in identical 8-SOIC packages. The AD8022ARZ maintains active product status with full RoHS3 compliance and MSL 1 rating. The device operates within the required temperature range and supports the 5 V to 12 V supply voltage specification. The AD8022ARZ exhibits lower supply current consumption (4 mA versus 11 mA) and improved input bias current characteristics (2.5 µA versus 5 µA), representing a performance enhancement. The slew rate specification of 50 V/µs exceeds the original 40 V/µs requirement. The gain bandwidth product of 100 MHz is slightly lower than the original 130 MHz specification but remains within acceptable operational parameters for most voltage feedback amplifier applications.

AD8012ARZ / AD8012ARZ-REEL / AD8012ARZ-REEL7 - Alternative Substitute

The AD8012 series devices are current feedback amplifiers available in three packaging configurations: tube (AD8012ARZ), tape and reel (AD8012ARZ-REEL), and cut tape with Digi-Reel (AD8012ARZ-REEL7). These devices share the 8-SOIC package footprint and dual-channel configuration. All variants maintain active product status with full RoHS3 compliance and MSL 1 rating. The current feedback topology differs from the original voltage feedback design, resulting in significantly higher slew rate (2250 V/µs) and bandwidth characteristics. Supply voltage compatibility extends from 3 V to 12 V, providing broader operational range. Output current per channel is 125 mA, lower than the original 320 mA specification. These devices are suitable for applications where higher frequency response and slew rate are beneficial, though circuit design modifications may be required due to the fundamental amplifier topology difference.

AD8017ARZ / AD8017ARZ-REEL / AD8017ARZ-REEL7 - Alternative Substitute

The AD8017 series devices are general purpose amplifiers available in three packaging configurations: tube (AD8017ARZ), reel (AD8017ARZ-REEL), and cut tape with Digi-Reel (AD8017ARZ-REEL7). These devices share the 8-SOIC package footprint and dual-channel configuration. All variants maintain active product status with full RoHS3 compliance and MSL 1 rating. The general purpose topology provides intermediate performance characteristics between voltage feedback and current feedback designs. Supply voltage compatibility extends from 4.4 V to 12 V. Output current per channel is 270 mA, approaching the original 320 mA specification. These devices are suitable for applications requiring balanced performance across frequency and slew rate parameters.

Frequently Asked Questions (FAQ)

Q: Can the AD8022ARZ be used as a direct pin-for-pin replacement for the TS613IDT?

A: Yes. Both devices are dual-channel operational amplifiers in 8-SOIC packages with identical pin configurations and footprints. The AD8022ARZ maintains voltage feedback topology and operates within the required temperature and supply voltage ranges. No PCB modifications are required for physical installation.

Q: What are the key differences between the AD8022ARZ and the AD8012ARZ?

A: The primary difference is amplifier topology. The AD8022ARZ is a voltage feedback amplifier, matching the original TS613IDT design. The AD8012ARZ is a current feedback amplifier with significantly higher slew rate (2250 V/µs versus 50 V/µs) and bandwidth characteristics. Voltage feedback amplifiers are typically preferred for precision applications requiring low input offset voltage and stable gain characteristics. Current feedback amplifiers excel in high-speed applications. Circuit design considerations differ between these topologies.

Q: Are all AD8012 and AD8017 variants electrically identical?

A: Yes. The AD8012ARZ, AD8012ARZ-REEL, and AD8012ARZ-REEL7 are electrically identical devices with different packaging and delivery formats. Similarly, AD8017ARZ, AD8017ARZ-REEL, and AD8017ARZ-REEL7 are electrically identical. The packaging designation (tube, tape and reel, or cut tape) affects only the physical delivery method and quantity per reel, not electrical performance.

Q: What is the significance of the -REEL and -REEL7 suffixes?

A: These suffixes indicate packaging format for automated assembly. The -REEL designation indicates standard tape and reel packaging. The -REEL7 designation indicates cut tape with Digi-Reel format. The base part number (AD8012, AD8017, AD8022) without these suffixes typically indicates tube packaging. All formats contain identical die and electrical specifications.

Q: Does the lower supply current of the AD8022ARZ affect circuit design?

A: The AD8022ARZ requires 4 mA total supply current compared to 11 mA for the TS613IDT. This reduction may improve power supply efficiency and reduce thermal dissipation in the application. No circuit design modifications are required; the lower current consumption is a performance benefit. Ensure that power supply decoupling capacitors remain properly specified per the AD8022ARZ datasheet recommendations.

Q: Can the AD8017 series be used if higher output current is required?

A: The AD8017 series provides 270 mA output current per channel, compared to 320 mA for the TS613IDT. If the application requires the full 320 mA output current specification, the AD8017 series may not be suitable. The AD8022ARZ provides only 55 mA output current and is not suitable for high output current applications. Application-specific current requirements must be verified against substitute part specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts (AD8022ARZ, AD8012 series, and AD8017 series) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original TS613IDT specifications. All devices are suitable for applications with RoHS compliance requirements.

Q: What is the impact of the gain bandwidth product difference between TS613IDT (130 MHz) and AD8022ARZ (100 MHz)?

A: The AD8022ARZ gain bandwidth product of 100 MHz is approximately 77% of the original 130 MHz specification. For applications operating at frequencies significantly below 100 MHz, this difference has minimal impact. Applications requiring operation near or above 100 MHz should verify that the reduced bandwidth does not compromise performance. Closed-loop gain and frequency response characteristics must be evaluated for specific circuit configurations.

Q: Is the AD8018ARZ a suitable substitute?

A: No. The AD8018ARZ is classified as an Interface device (xDSL driver) rather than a linear amplifier. Although it shares the 8-SOIC package and operates within the same temperature range, it is functionally incompatible with the TS613IDT voltage feedback amplifier application. The AD8018ARZ is not suitable for general-purpose amplifier applications.
