Parameter Comparison

Engineering Selection Recommendations

AD826ARZ / AD826ARZ-REEL / AD826ARZ-REEL7 Selection:

The AD826 series represents the primary substitute for the THS4022IDR. These devices maintain identical package geometry, circuit count, and operating temperature specifications. The AD826 series is manufactured by Analog Devices Inc. with active product status, ensuring sustained availability and manufacturing support. All three variants (AD826ARZ, AD826ARZ-REEL, AD826ARZ-REEL7) are functionally equivalent, differing only in packaging format: tube packaging for AD826ARZ, and cut tape with Digi-Reel® for AD826ARZ-REEL and AD826ARZ-REEL7 variants.

The AD826 series exhibits lower bandwidth performance (50 MHz -3dB bandwidth versus 350 MHz for the THS4022IDR) and reduced output current capability (50 mA per channel versus 100 mA). These devices are suitable for applications where the THS4022IDR's high-speed characteristics are not required. The AD826 series supports a wider minimum supply voltage (5V versus 9V) and maintains ROHS3 compliance with MSL 1 rating.

AD828ARZ / AD828ARZ-REEL7 Selection:

The AD828 series provides an alternative substitute with enhanced bandwidth performance (130 MHz -3dB bandwidth) and slew rate (450V/µs), positioning it between the AD826 and THS4022IDR in terms of speed capability. The AD828 series maintains identical package specifications and operating temperature range. Both AD828ARZ and AD828ARZ-REEL7 variants are functionally equivalent, differing in packaging format.

The AD828 series operates at higher supply current (14 mA total) compared to the THS4022IDR (7.8mA) and maintains 50 mA output current per channel. This device supports both single supply (5V to 36V) and dual supply (±2.5V to ±18V) configurations. The AD828 series is suitable for applications requiring intermediate bandwidth performance with active product status and full ROHS3 compliance.

Packaging Considerations:

Selection between tube packaging (ARZ) and cut tape with Digi-Reel® packaging (ARZ-REEL, ARZ-REEL7) depends on procurement and assembly requirements. Tube packaging accommodates manual handling and smaller quantity orders. Cut tape with Digi-Reel® packaging supports automated pick-and-place assembly processes and high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can the AD826ARZ directly replace the THS4022IDR in all applications?

A: The AD826ARZ maintains mechanical and package compatibility with the THS4022IDR. However, the AD826ARZ operates at significantly lower bandwidth (50 MHz versus 350 MHz) and reduced output current (50 mA versus 100 mA per channel). Direct substitution is valid only for applications where these reduced performance specifications are acceptable. Circuit redesign or performance verification is necessary if the original design relied on the THS4022IDR's high-speed characteristics.

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

A: These three part numbers are functionally identical voltage feedback amplifiers. The differences are packaging format only: AD826ARZ is supplied in tube packaging, while AD826ARZ-REEL and AD826ARZ-REEL7 are supplied in cut tape with Digi-Reel® format. Selection depends on assembly process requirements and procurement volume. All three variants maintain identical electrical specifications and compliance certifications.

Q: Is the AD828ARZ a better substitute than the AD826ARZ?

A: The AD828ARZ provides higher bandwidth (130 MHz -3dB bandwidth) and faster slew rate (450V/µs) compared to the AD826ARZ (50 MHz, 350V/µs), positioning it closer to the THS4022IDR's performance envelope. However, the AD828ARZ operates at higher supply current (14 mA versus 6.6mA for the AD826). Selection between AD828 and AD826 depends on application bandwidth requirements and power budget constraints. Both devices are active products with full compliance certifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The AD826ARZ, AD826ARZ-REEL, AD826ARZ-REEL7, AD828ARZ, and AD828ARZ-REEL7 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the THS4022IDR compliance profile.

Q: What supply voltage range do the substitute parts support?

A: The AD826 series supports 5V to 36V single supply operation, providing a wider minimum voltage range than the THS4022IDR (9V minimum). The AD828 series supports both single supply (5V to 36V) and dual supply (±2.5V to ±18V) configurations. Both substitute families exceed the THS4022IDR's maximum supply voltage specification of 32V, supporting 36V operation.

Q: Can I use the AD828ARZ in place of the AD826ARZ?

A: The AD828ARZ and AD826ARZ maintain identical package geometry and circuit count. However, the AD828ARZ operates at higher supply current (14 mA versus 6.6mA) and provides higher bandwidth (130 MHz versus 50 MHz). Substitution is mechanically and electrically feasible, but circuit redesign may be necessary to accommodate the increased power consumption and verify that the higher bandwidth does not introduce stability issues in the application.

Q: What is the inventory status of these substitute parts?

A: The AD826ARZ is available with 12,600 pieces in stock. The AD826ARZ-REEL has 2,640 pieces in stock. The AD826ARZ-REEL7 has 5,686 pieces in stock. The AD828ARZ has 1,633 pieces in stock. The AD828ARZ-REEL7 has 16,450 pieces in stock. All substitute parts maintain active product status with Analog Devices Inc., ensuring continued availability.
