Engineering Selection Recommendations

Primary Recommendation: TSH82IDT

TSH82IDT is the direct active equivalent of the obsolete TSH82ID. This part maintains identical electrical specifications, automotive AEC-Q100 qualification, and 8-SOIC packaging. TSH82IDT is available in Cut Tape and Digi-Reel packaging formats with substantial inventory (339,427 units). Selection of TSH82IDT eliminates all compatibility risk and requires no circuit redesign.

Secondary Recommendations: Voltage Feedback Amplifiers

The AD8042ARZ, AD8042ARZ-REEL, AD8042ARZ-REEL7, AD8052ARZ, AD8052ARZ-REEL, and AD8052ARZ-REEL7 devices from Analog Devices Inc. provide enhanced performance characteristics including higher slew rates (170–225 V/µs), improved bandwidth (110–170 MHz), and lower input offset voltage (1.7–3 mV). These parts maintain 8-SOIC packaging, dual-circuit configuration, and rail-to-rail output. The AD8042 series supports supply voltages as low as 3 V, extending design flexibility. The AD8052 series extends operating temperature to 125°C. All variants are ROHS3 compliant and carry AEC-Q100 qualification where applicable.

Frequently Asked Questions (FAQ)

Q: Can TSH82IDT be used as a direct replacement for TSH82ID?

A: Yes. TSH82IDT is the active production equivalent of TSH82ID with identical electrical specifications, package type (8-SOIC), and automotive qualification (AEC-Q100). The only difference is product status (Active vs. Obsolete) and packaging format availability (Cut Tape & Digi-Reel vs. standard).

Q: What is the primary difference between TSH82ID and the AD8042 series?

A: The TSH82ID is classified as a general-purpose amplifier, while the AD8042 series is classified as voltage feedback amplifiers. The AD8042 series provides superior performance with 225 V/µs slew rate (versus 118 V/µs), 90 MHz gain bandwidth product (versus 65 MHz), and lower input offset voltage (3 mV versus 800 µV). Both maintain 8-SOIC packaging and dual-circuit configuration.

Q: Are all substitute parts compatible with the TSH82ID supply voltage range of 4.5 V to 12 V?

A: TSH82IDT, AD8042ARZ variants, AD8052ARZ variants, and LMH6643 variants all support the 4.5 V to 12 V supply range. The LT1804IS8#PBF supports a lower minimum supply voltage of 2.3 V, which is compatible with the 4.5 V to 12 V range.

Q: What is the difference between AD8042ARZ, AD8042ARZ-REEL, and AD8042ARZ-REEL7?

A: These three part numbers are electrically identical. The differences are in packaging format: AD8042ARZ is supplied in Tube packaging, while AD8042ARZ-REEL and AD8042ARZ-REEL7 are supplied in Cut Tape and Digi-Reel format. Selection depends on procurement and assembly requirements.

Q: Can the AD8052ARZ be used in applications requiring -40°C to 85°C operation?

A: Yes. The AD8052ARZ supports an extended operating temperature range of -40°C to 125°C, which encompasses the -40°C to 85°C requirement of the TSH82ID.

Q: What is the key advantage of the LMH6643 series over the TSH82ID?

A: The LMH6643 series provides lower supply current consumption (2.7 mA per channel versus 9.8 mA) and higher output current capability (75 mA per channel versus 55 mA). These characteristics make the LMH6643 suitable for power-sensitive and high-load applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All recommended substitute parts (TSH82IDT, AD8042 variants, AD8052 variants, LMH6643 variants, and LT1804IS8#PBF) are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Which substitute part has the lowest input offset voltage?

A: The LMH6643MA/NOPB and LMH6643MAX/NOPB have the lowest input offset voltage at 1 mV, compared to 800 µV for the TSH82ID and 3 mV for the AD8042 series.

Q: Is automotive AEC-Q100 qualification available for all substitute parts?

A: TSH82IDT carries AEC-Q100 qualification. Verification of AEC-Q100 qualification status for alternative manufacturers (Analog Devices Inc. and Texas Instruments) should be confirmed directly with the respective manufacturers or authorized distributors for specific part numbers.

Q: What packaging options are available for TSH82IDT?

A: TSH82IDT is available in Cut Tape (CT) and Digi-Reel packaging formats. Standard Tube packaging is not listed for this part number.
