Substitute Part Grouping Explanation

Substitution of the THS4022IDRG4 is determined by strict alignment of electrical and mechanical parameters within the voltage feedback amplifier category. The following criteria establish valid substitution relationships:

Primary Substitution Criteria:

• Amplifier Type: Voltage Feedback (required match)
• Number of Circuits: 2 (required match)
• Package / Case: 8-SOIC (required match)
• Mounting Type: Surface Mount (required match)
• Operating Temperature Range: -40°C ~ 85°C (required match)
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) (required match)

Secondary Electrical Parameters for Compatibility Assessment:

• Voltage - Supply Span compatibility (substitute minimum ≤ 9 V; substitute maximum ≥ 32 V)
• Current - Output / Channel (substitute ≥ 100 mA for direct replacement; lower values indicate reduced output capability)
• Slew Rate and Gain Bandwidth Product (performance characteristics; lower values indicate reduced speed capability)

The substitute parts identified below meet all primary criteria. Variations in secondary electrical parameters indicate performance trade-offs that must be evaluated against specific application requirements.

Engineering Selection Recommendations

AD826ARZ, AD826ARZ-REEL, and AD826ARZ-REEL7 (Analog Devices Inc.)

These three variants represent the same electrical device with different packaging configurations. All three are active products with ROHS3 compliance and MSL 1 rating. The AD826 series operates within the required supply voltage range (5 V to 36 V) and maintains the same input offset voltage and input bias current specifications as the THS4022IDRG4. However, the AD826 series exhibits reduced output current capability (50 mA per channel versus 100 mA) and lower bandwidth performance (50 MHz versus 350 MHz). Selection among these three variants depends on packaging requirements: AD826ARZ is supplied in Tube packaging, while AD826ARZ-REEL and AD826ARZ-REEL7 are supplied in Cut Tape and Digi-Reel formats.

AD828ARZ and AD828ARZ-REEL7 (Analog Devices Inc.)

These two variants represent the same electrical device with different packaging configurations. Both are active products with ROHS3 compliance and MSL 1 rating. The AD828 series operates within the required supply voltage range and delivers higher bandwidth performance (130 MHz) compared to the AD826 series, though still below the THS4022IDRG4 specification (350 MHz). The AD828 series maintains 50 mA output current per channel and exhibits higher supply current consumption (14 mA total). Selection between AD828ARZ (Tube packaging) and AD828ARZ-REEL7 (Cut Tape and Digi-Reel packaging) depends on packaging requirements.

Substitution Feasibility Summary

All identified substitute parts satisfy the mandatory substitution criteria: voltage feedback amplifier type, dual-circuit configuration, 8-SOIC package, surface mount mounting, -40°C to 85°C operating temperature range, ROHS3 compliance, and MSL 1 rating. The primary trade-off across all substitutes is reduced output current capability (50 mA versus 100 mA per channel). The AD826 series represents a lower-performance alternative with reduced bandwidth, while the AD828 series provides intermediate bandwidth performance. Selection should be based on application-specific bandwidth and output current requirements.

Frequently Asked Questions (FAQ)

Q: Can the AD826ARZ directly replace the THS4022IDRG4 in all applications?

A: The AD826ARZ meets all mandatory substitution criteria for package, mounting type, circuit configuration, and compliance standards. However, the AD826ARZ delivers 50 mA output current per channel compared to the THS4022IDRG4's 100 mA, and operates at 50 MHz bandwidth versus 350 MHz. Applications requiring the full 100 mA output current or 350 MHz bandwidth cannot use the AD826ARZ as a direct replacement.

Q: What is the difference between AD826ARZ, AD826ARZ-REEL, and AD826ARZ-REEL7?

A: These three part numbers represent identical electrical devices with different packaging and delivery formats. AD826ARZ is supplied in Tube packaging. AD826ARZ-REEL and AD826ARZ-REEL7 are supplied in Cut Tape and Digi-Reel formats. The electrical specifications and performance characteristics are identical across all three variants.

Q: What is the difference between AD828ARZ and AD828ARZ-REEL7?

A: These two part numbers represent identical electrical devices with different packaging and delivery formats. AD828ARZ is supplied in Tube packaging. AD828ARZ-REEL7 is supplied in Cut Tape and Digi-Reel format. The electrical specifications and performance characteristics are identical between the two variants.

Q: How does the AD828 series compare to the AD826 series?

A: The AD828 series delivers higher bandwidth performance (130 MHz) compared to the AD826 series (50 MHz). Both series maintain 50 mA output current per channel. The AD828 series requires higher supply current (14 mA total) compared to the AD826 series (6.6 mA total). Both series operate within the same supply voltage range (5 V to 36 V).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts (AD826ARZ, AD826ARZ-REEL, AD826ARZ-REEL7, AD828ARZ, and AD828ARZ-REEL7) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the THS4022IDRG4.

Q: What is the primary limitation when substituting the THS4022IDRG4?

A: The primary limitation across all identified substitutes is reduced output current capability. The THS4022IDRG4 delivers 100 mA per channel, while all substitute parts deliver 50 mA per channel. Applications requiring output currents exceeding 50 mA per channel require alternative component selection or external buffering.

Q: Can the substitute parts operate across the full 9 V to 32 V supply range of the THS4022IDRG4?

A: Yes. All substitute parts operate across a 5 V to 36 V supply range, which encompasses and exceeds the THS4022IDRG4's 9 V to 32 V range. The substitute parts support operation at lower minimum supply voltages (5 V versus 9 V) and higher maximum supply voltages (36 V versus 32 V).

Q: Which substitute part offers the closest performance match to the THS4022IDRG4?

A: The AD828 series offers the closest bandwidth performance match with 130 MHz operation, though this remains below the THS4022IDRG4's 350 MHz specification. The AD828 series slew rate (450 V/µs) closely approaches the THS4022IDRG4 specification (470 V/µs). However, all substitute parts are limited to 50 mA output current per channel versus the THS4022IDRG4's 100 mA capability.
