Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8091ART-REEL7 is determined by compatibility across the following critical parameters: package type (SOT-23-5), mounting method (surface mount), output configuration (rail-to-rail), number of circuits (single), and electrical operating ranges (supply voltage, temperature, and output current capability).

The substitute parts are grouped into two categories:

Direct Equivalent: AD8091ARTZ-R7 is a direct functional equivalent manufactured by Analog Devices Inc. with identical electrical specifications and active product status, differing only in packaging format (Cut Tape & Digi-Reel® versus reel packaging).

Functional Alternatives: ADA4891-1ARJZ-RL, OPA725AIDBVR, OPA725AIDBVT, and TSH80IYLT are general-purpose amplifiers that share the SOT-23-5 package, rail-to-rail output, and single-circuit configuration. These alternatives operate within overlapping supply voltage ranges and temperature specifications, though with variations in bandwidth, slew rate, and input bias current characteristics.

Parameter Comparison

Engineering Selection Recommendations

AD8091ARTZ-R7 is the primary substitute for the AD8091ART-REEL7. This part maintains identical electrical performance specifications and is manufactured by the same supplier (Analog Devices Inc.). The AD8091ARTZ-R7 holds active product status with ROHS3 compliance and unlimited moisture sensitivity rating, providing superior long-term availability and regulatory compliance compared to the obsolete original part. The only distinction is packaging format, which does not affect electrical or mechanical compatibility in the end application.

ADA4891-1ARJZ-RL is suitable for applications where higher bandwidth (240 MHz) and faster slew rate (210V/µs) are beneficial. This part operates within a narrower supply voltage range (2.7V to 5.5V maximum) and exhibits significantly lower input bias current (2 pA). The ADA4891-1ARJZ-RL is ROHS3 compliant and active, with extended operating temperature range to 125°C. Selection of this part requires verification that the application supply voltage does not exceed 5.5V.

OPA725AIDBVR and OPA725AIDBVT are Texas Instruments general-purpose amplifiers with identical electrical specifications. These parts feature lower slew rate (30V/µs) and reduced output current capability (40 mA) compared to the AD8091ART-REEL7. The OPA725 series operates across the full 4V to 12V supply range and extends to 125°C operating temperature. Both variants are ROHS3 compliant and active. The OPA725AIDBVR has higher inventory availability (4500 units) compared to OPA725AIDBVT (1803 units). These parts are appropriate for applications where bandwidth and slew rate requirements are less stringent than the original specification.

TSH80IYLT is an STMicroelectronics general-purpose amplifier with automotive qualification (AEC-Q100) and active product status. This part exhibits higher supply current (9.8 mA) and operates within a narrower minimum supply voltage range (4.5V minimum). The TSH80IYLT provides the highest inventory availability (65,100 units) among all substitutes and maintains unlimited moisture sensitivity rating. Selection of this part is appropriate for automotive applications or where high inventory availability is a procurement priority, provided the application supply voltage remains above 4.5V.

Frequently Asked Questions (FAQ)

Q: Can AD8091ARTZ-R7 be used as a direct replacement for AD8091ART-REEL7?

A: Yes. The AD8091ARTZ-R7 is a direct functional equivalent with identical electrical specifications, operating ranges, and package type. The difference in packaging format (Cut Tape & Digi-Reel® versus reel) does not affect circuit performance or mechanical compatibility. The AD8091ARTZ-R7 is active and ROHS3 compliant, providing superior long-term availability.

Q: What are the key differences between the AD8091ART-REEL7 and ADA4891-1ARJZ-RL?

A: The ADA4891-1ARJZ-RL offers higher bandwidth (240 MHz versus 110 MHz), faster slew rate (210V/µs versus 170V/µs), and significantly lower input bias current (2 pA versus 1.4 µA). However, the ADA4891-1ARJZ-RL has a maximum supply voltage of 5.5V, which is lower than the AD8091ART-REEL7 maximum of 12V. Applications operating above 5.5V supply voltage cannot use the ADA4891-1ARJZ-RL.

Q: Are the OPA725AIDBVR and OPA725AIDBVT interchangeable?

A: Yes. The OPA725AIDBVR and OPA725AIDBVT have identical electrical specifications and package type. The difference is in packaging format and inventory availability. Both are ROHS3 compliant and active. Selection between them depends on procurement requirements and available inventory.

Q: What is the significance of the TSH80IYLT automotive qualification?

A: The TSH80IYLT carries AEC-Q100 qualification, indicating it meets automotive industry reliability and quality standards. This qualification is relevant only for applications requiring automotive-grade components. For non-automotive applications, the automotive qualification does not provide additional benefit.

Q: Can I use OPA725AIDBVR in a 12V supply application?

A: Yes. The OPA725AIDBVR operates across a 4V to 12V supply range, making it compatible with 12V supply applications. However, the OPA725AIDBVR has lower slew rate (30V/µs) and reduced output current capability (40 mA) compared to the AD8091ART-REEL7, which may affect performance in high-speed or high-current output applications.

Q: What is the minimum supply voltage requirement for TSH80IYLT?

A: The TSH80IYLT requires a minimum supply voltage of 4.5V. Applications operating below 4.5V supply voltage cannot use this part. The AD8091ART-REEL7 and AD8091ARTZ-R7 support operation down to 3V, providing greater flexibility for low-voltage applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (AD8091ARTZ-R7, ADA4891-1ARJZ-RL, OPA725AIDBVR, OPA725AIDBVT, and TSH80IYLT) are ROHS3 compliant. The original AD8091ART-REEL7 does not specify RoHS status due to its obsolete classification.

Q: Which substitute part has the lowest input bias current?

A: The ADA4891-1ARJZ-RL has the lowest input bias current at 2 pA, compared to 1.4 µA for the AD8091ART-REEL7. This characteristic is beneficial for high-impedance input applications where input bias current drift and leakage are critical design parameters.

Q: What is the moisture sensitivity level (MSL) difference between substitutes?

A: The AD8091ARTZ-R7 and TSH80IYLT have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The OPA725AIDBVR and OPA725AIDBVT have MSL 2 (1 Year), requiring storage and handling within specified humidity conditions for one year from the date of manufacture. The ADA4891-1ARJZ-RL has MSL 1 (Unlimited).
