Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS1002IM8 is determined by the following critical parameters:

Functional Equivalence Criteria:

• Dual-channel general-purpose operational amplifier architecture
• Rail-to-rail output capability
• Surface mount packaging with 8-pin configuration
• Low-power supply operation

Electrical Compatibility Parameters:

• Slew rate performance (0.0015 V/µs minimum)
• Gain bandwidth product (4 kHz minimum)
• Input bias current specification
• Output current capability per channel
• Supply voltage range compatibility
• Input offset voltage tolerance

The TLV8802DGKT from Texas Instruments satisfies these substitution criteria through matching functional topology, package form factor, and electrical performance envelope. The substitute part maintains compatibility with existing PCB layouts while offering enhanced specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The TLV8802DGKT is the direct substitute for the obsolete TS1002IM8. Selection of the TLV8802DGKT is based on the following engineering factors:

Product Status: The TS1002IM8 is classified as obsolete, making the active TLV8802DGKT the appropriate choice for ongoing production and new designs requiring long-term component availability.

Compliance and Certifications: Both devices share identical ECCN (EAR99) and HTSUS classifications, ensuring equivalent regulatory treatment. The TLV8802DGKT carries RoHS3 compliance and REACH unaffected status, meeting current environmental standards.

Electrical Performance: The TLV8802DGKT meets or exceeds all critical electrical parameters of the TS1002IM8. The substitute provides superior input bias current performance (0.1 pA versus 25 pA), higher output current capability (4.7 mA versus 1.5 mA per channel), and improved gain bandwidth product (6 kHz versus 4 kHz).

Package Compatibility: Both devices utilize identical 8-pin surface mount packaging (8-TSSOP, 8-MSOP with 0.118" / 3.00mm width), enabling direct PCB layout compatibility without redesign.

Supply Voltage Considerations: The TLV8802DGKT operates across a wider supply voltage range (1.7 V to 5.5 V) compared to the TS1002IM8 (0.65 V to 2.5 V). Designs operating within the TS1002IM8 supply range remain fully compatible with the substitute.

Frequently Asked Questions (FAQ)

Q: Can the TLV8802DGKT be used as a direct replacement for the TS1002IM8 on existing PCBs?

A: Yes. Both devices share identical 8-pin surface mount package geometry (8-TSSOP, 8-MSOP with 0.118" / 3.00mm width), enabling direct PCB substitution without layout modifications.

Q: What are the key electrical differences between these devices?

A: The TLV8802DGKT provides superior input bias current (0.1 pA versus 25 pA), higher output current per channel (4.7 mA versus 1.5 mA), and improved gain bandwidth product (6 kHz versus 4 kHz). Both maintain identical slew rate performance (0.0015 V/µs) and input offset voltage specifications within acceptable tolerance.

Q: Are there supply voltage compatibility concerns when substituting?

A: The TLV8802DGKT operates across a wider supply voltage range (1.7 V to 5.5 V) than the TS1002IM8 (0.65 V to 2.5 V). Existing designs operating within the TS1002IM8 range remain fully compatible. Designs requiring operation below 1.7 V require evaluation of the substitute's minimum supply specification.

Q: What is the operating temperature difference between these parts?

A: The TS1002IM8 operates from -40°C to 85°C, while the TLV8802DGKT extends to -40°C to 125°C. The substitute provides extended high-temperature capability for applications requiring operation above 85°C.

Q: Do both devices have identical moisture sensitivity ratings?

A: Yes. Both the TS1002IM8 and TLV8802DGKT carry MSL 1 (Unlimited) moisture sensitivity level, indicating identical handling and storage requirements.

Q: Are there regulatory or compliance differences?

A: Both devices share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications. The TLV8802DGKT additionally carries RoHS3 compliance and REACH unaffected status, meeting current environmental regulations.

Q: What is the supply current difference between these devices?

A: The TLV8802DGKT draws significantly lower supply current (320 nA across both channels) compared to the TS1002IM8 (1.2 µA across both channels), providing improved power efficiency for battery-powered applications.
