Engineering Selection Recommendations
Primary Substitute Group: Analog Devices AD8602 Series
The AD8602 series (AD8602ARZ, AD8602ARZ-REEL, AD8602ARZ-REEL7, AD8602DRZ, AD8602DRZ-REEL, AD8602DRZ-REEL7, AD8602WARZ-R7, AD8602WARZ-RL) represents the most direct functional replacement for the TSV622ID. All variants maintain active product status, ROHS3 compliance, and unlimited moisture sensitivity (MSL 1). These devices are pin-compatible dual-channel CMOS rail-to-rail amplifiers in 8-SOIC packaging.
The AD8602 series exhibits enhanced performance characteristics compared to the TSV622ID, including higher slew rate (6 V/µs versus 0.14 V/µs), significantly higher gain bandwidth product (8.4 MHz versus 420 kHz), and lower input bias current (0.2 pA versus 1 pA). The minimum supply voltage requirement increases from 1.5 V to 2.7 V, which must be evaluated against application constraints.
Selection among AD8602 variants depends on packaging requirements: tube packaging (AD8602ARZ, AD8602DRZ), tape and reel (AD8602ARZ-REEL, AD8602DRZ-REEL), cut tape with Digi-Reel (AD8602ARZ-REEL7, AD8602DRZ-REEL7, AD8602WARZ-R7), or unspecified packaging (AD8602WARZ-RL). Input offset voltage specifications vary between 80 µV (AD8602ARZ, AD8602ARZ-REEL, AD8602ARZ-REEL7, AD8602WARZ-R7, AD8602WARZ-RL) and 1.3 mV (AD8602DRZ, AD8602DRZ-REEL, AD8602DRZ-REEL7).
Secondary Substitute: Diodes Incorporated AZV832MTR-G1
The AZV832MTR-G1 provides an alternative CMOS dual-channel rail-to-rail amplifier in 8-SOIC packaging with active product status and ROHS3 compliance. This device operates across a supply voltage range of 1.6 V to 5.5 V, which more closely aligns with the TSV622ID minimum supply requirement (1.5 V) compared to the AD8602 series (2.7 V minimum).
The AZV832MTR-G1 exhibits performance characteristics intermediate between the TSV622ID and AD8602 series: slew rate of 0.45 V/µs (higher than TSV622ID but lower than AD8602), gain bandwidth product of 1 MHz (higher than TSV622ID but lower than AD8602), and input bias current of 1 pA (matching TSV622ID). Output current capability is significantly higher at 185 mA per channel compared to 74 mA for the TSV622ID.
The AZV832MTR-G1 operates across a reduced temperature range (-40°C to 85°C) compared to the TSV622ID (-40°C to 125°C), which may limit applicability in high-temperature environments. Moisture sensitivity level is MSL 3 (168 hours), requiring more stringent handling compared to MSL 1 devices.
Tertiary Substitute: Analog Devices/Maxim MAX4246ASA+
The MAX4246ASA+ is a general-purpose dual-channel rail-to-rail amplifier in 8-SOIC packaging with active product status, ROHS3 compliance, and unlimited moisture sensitivity (MSL 1). This device operates across a supply voltage range of 2.5 V to 5.5 V and maintains the full operating temperature range of -40°C to 125°C.
The MAX4246ASA+ exhibits lower performance specifications compared to the TSV622ID in slew rate (0.4 V/µs versus 0.14 V/µs is comparable) and gain bandwidth product (1 MHz versus 420 kHz). Input bias current is significantly higher at 10 nA compared to 1 pA for the TSV622ID. Output current capability is lower at 30 mA per channel compared to 74 mA for the TSV622ID. Supply current is higher at 375 µA (per dual channels) compared to 29 µA for the TSV622ID.
The MAX4246ASA+ is suitable for applications where general-purpose amplification is required and the higher input bias current and lower output current capability are acceptable trade-offs.
Frequently Asked Questions (FAQ)
Q: Can the AD8602 series directly replace the TSV622ID in existing designs?
A: The AD8602 series maintains electrical and mechanical compatibility through identical 8-SOIC packaging, dual-channel configuration, rail-to-rail output, and CMOS amplifier topology. However, the minimum supply voltage increases from 1.5 V to 2.7 V. Designs operating at supply voltages below 2.7 V require alternative substitutes such as the AZV832MTR-G1 (1.6 V minimum) or TSV622ID retention. Performance enhancements in the AD8602 series (higher slew rate, gain bandwidth product, and lower input offset voltage) may require circuit re-evaluation in applications with tight bandwidth or settling time constraints.
Q: What is the significance of the different AD8602 packaging variants?
A: The AD8602 series is available in multiple packaging formats: tube (AD8602ARZ, AD8602DRZ), tape and reel (AD8602ARZ-REEL, AD8602DRZ-REEL), and cut tape with Digi-Reel (AD8602ARZ-REEL7, AD8602DRZ-REEL7, AD8602WARZ-R7). Packaging selection depends on procurement and assembly requirements. Tube packaging is suitable for manual handling and small-volume assembly. Tape and reel formats are optimized for automated pick-and-place equipment. Cut tape with Digi-Reel provides flexibility for mixed-volume production. All variants are electrically identical within their respective temperature and offset voltage grades.
Q: Why does the AZV832MTR-G1 have a lower maximum operating temperature than the TSV622ID?
A: The AZV832MTR-G1 is specified for operation from -40°C to 85°C, compared to the TSV622ID range of -40°C to 125°C. This represents a design limitation of the AZV832 device family. Applications requiring operation above 85°C must utilize the TSV622ID, AD8602 series, or MAX4246ASA+ (all rated to 125°C).
Q: What is the impact of moisture sensitivity level differences between substitute parts?
A: The TSV622ID, AD8602 series, and MAX4246ASA+ are all classified as MSL 1 (unlimited moisture sensitivity), indicating no special moisture control requirements during storage or handling. The AZV832MTR-G1 is classified as MSL 3 (168 hours), requiring storage in dry conditions and limiting the time the component can be exposed to ambient humidity before soldering. MSL 3 components require more rigorous handling procedures and may increase procurement and assembly costs.
Q: How do the supply current specifications affect power consumption in battery-powered applications?
A: The TSV622ID draws 29 µA total supply current, making it suitable for ultra-low-power applications. The AD8602 series draws 750 µA (per dual channels), approximately 26 times higher. The AZV832MTR-G1 draws 70 µA, approximately 2.4 times higher than the TSV622ID. The MAX4246ASA+ draws 375 µA (per dual channels), approximately 13 times higher. For battery-powered designs with strict power budgets, the TSV622ID or AZV832MTR-G1 are preferred. The AD8602 and MAX4246ASA+ are suitable for applications where higher performance justifies increased power consumption.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All identified substitute parts (AD8602 series, AZV832MTR-G1, and MAX4246ASA+) maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original TSV622ID component.
Q: What is the difference between AD8602ARZ and AD8602DRZ variants?
A: Both AD8602ARZ and AD8602DRZ are CMOS dual-channel rail-to-rail amplifiers in 8-SOIC packaging with identical electrical specifications except for input offset voltage. The AD8602ARZ specifies 80 µV maximum input offset voltage, while the AD8602DRZ specifies 1.3 mV maximum input offset voltage. The AD8602ARZ is suitable for precision applications requiring low offset voltage. The AD8602DRZ is suitable for general-purpose applications where higher offset voltage is acceptable. Both are available in multiple packaging formats (tube, tape and reel, cut tape with Digi-Reel).
Q: Can the MAX4246ASA+ be used in applications requiring high output current?
A: The MAX4246ASA+ provides 30 mA output current per channel, compared to 74 mA for the TSV622ID and 50 mA for the AD8602 series. Applications requiring output currents exceeding 30 mA per channel should utilize the TSV622ID, AD8602 series, or AZV832MTR-G1 (185 mA per channel). The MAX4246ASA+ is suitable for signal conditioning and low-current buffering applications.
