Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSH82IPT is determined by strict adherence to the following electrical and mechanical parameters:

Mechanical Compatibility: All substitute parts must utilize the 8-TSSOP surface-mount package with identical 0.173" (4.40mm) width to ensure PCB layout compatibility without redesign.

Electrical Compatibility: Substitute parts must maintain dual-circuit (2 circuits) general-purpose amplifier architecture with rail-to-rail output capability. The voltage supply span must encompass the original operating range (minimum 4.5 V to maximum 12 V). Operating temperature range must support the original specification of -40°C to 85°C.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating to ensure manufacturing process compatibility and long-term reliability.

The substitute parts identified—OP262DRUZ-REEL, OP262HRUZ, OP262HRUZ-REEL, and OP281GRUZ-REEL—satisfy these core substitution criteria. Variations in performance parameters such as slew rate, gain bandwidth product, input bias current, and supply current reflect different performance classes within the general-purpose amplifier category, but do not preclude functional substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Active Product Status Priority: All identified substitute parts maintain active product status with Analog Devices Inc., ensuring ongoing availability, manufacturing support, and technical documentation. The TSH82IPT obsolete status necessitates transition to an active alternative.

Compliance and Certification Alignment: All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with current manufacturing processes and supply chain requirements. No additional qualification or process validation is required based on these certifications.

Packaging and Mechanical Compatibility: All substitute parts utilize identical 8-TSSOP surface-mount packaging, enabling direct PCB layout compatibility without redesign. Packaging options vary (Cut Tape & Digi-Reel, Tube, Tape & Reel) to accommodate different procurement and assembly workflows.

Supply Voltage Consideration: The OP262 series (OP262DRUZ-REEL, OP262HRUZ, OP262HRUZ-REEL) supports a minimum supply voltage of 2.7 V, providing extended low-voltage operation capability beyond the TSH82IPT specification of 4.5 V minimum. The OP281GRUZ-REEL also supports 2.7 V minimum operation. Applications requiring operation at the original 4.5 V minimum threshold will function with all substitute parts.

Temperature Range Consideration: The OP262 series and OP281GRUZ-REEL support extended operating temperature range to 125°C, exceeding the original TSH82IPT specification of 85°C maximum. Applications limited to the original -40°C to 85°C range will function with all substitute parts.

Performance Class Selection: Selection among substitute parts depends on application-specific performance requirements. The OP262 series provides moderate performance characteristics (15 MHz gain bandwidth product, 13 V/µs slew rate). The OP281GRUZ-REEL provides ultra-low power operation (3.3 µA supply current per channel, 3 nA input bias current) with reduced bandwidth (105 kHz gain bandwidth product), suitable for battery-powered and low-power applications.

Frequently Asked Questions (FAQ)

Q: Can the OP262DRUZ-REEL, OP262HRUZ, OP262HRUZ-REEL, and OP281GRUZ-REEL be used interchangeably with the TSH82IPT?

A: All four substitute parts satisfy the core mechanical and electrical compatibility requirements: identical 8-TSSOP package, dual-circuit general-purpose amplifier architecture, rail-to-rail output, and compliance certifications. However, performance characteristics differ significantly. The OP262 series provides moderate bandwidth performance, while the OP281GRUZ-REEL prioritizes ultra-low power consumption. Selection depends on application-specific performance requirements.

Q: What is the difference between OP262DRUZ-REEL, OP262HRUZ, and OP262HRUZ-REEL?

A: These three parts share identical electrical specifications (15 MHz gain bandwidth product, 13 V/µs slew rate, 260 nA input bias current). The primary differences are packaging format and voltage offset specification. OP262DRUZ-REEL and OP262HRUZ-REEL are supplied in Cut Tape & Digi-Reel format, while OP262HRUZ is supplied in Tube format. OP262HRUZ and OP262HRUZ-REEL specify 1 mV input offset voltage, while OP262DRUZ-REEL specifies 800 µV input offset voltage.

Q: Why does the OP281GRUZ-REEL have significantly lower bandwidth than the TSH82IPT?

A: The OP281GRUZ-REEL is optimized for ultra-low power consumption (3.3 µA supply current per channel versus 9.8 mA for the TSH82IPT) and ultra-low input bias current (3 nA versus 6 µA). This optimization results in reduced bandwidth (105 kHz gain bandwidth product) and slew rate (0.028 V/µs). The OP281GRUZ-REEL is suitable for battery-powered and low-power applications where bandwidth requirements are modest.

Q: Are all substitute parts suitable for automotive applications?

A: The TSH82IPT carries automotive grade qualification (AEC-Q100). The substitute parts do not specify automotive grade qualification in the provided parameters. Applications requiring automotive qualification should be evaluated against specific automotive requirements and supplier documentation.

Q: What is the minimum supply voltage for each substitute part?

A: The TSH82IPT requires a minimum supply voltage of 4.5 V. All substitute parts support operation at 2.7 V minimum supply voltage, providing extended low-voltage capability. Applications designed for the original 4.5 V minimum threshold will function with all substitute parts.

Q: Can the OP262 series and OP281GRUZ-REEL operate at the same supply voltage as the TSH82IPT?

A: Yes. All substitute parts support the original TSH82IPT supply voltage range of 4.5 V to 12 V. The substitute parts additionally support extended operation down to 2.7 V minimum supply voltage.

Q: What is the maximum output current for each substitute part?

A: The TSH82IPT provides 55 mA output current per channel. The OP262 series provides 30 mA output current per channel. The OP281GRUZ-REEL provides 12 mA output current per channel. Applications requiring output currents exceeding 12 mA should select the OP262 series or verify compatibility with the OP281GRUZ-REEL specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing processes and environmental regulations.
