Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LMV982IDGSR are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameter Equivalence:

• Dual-channel general-purpose amplifier configuration
• Rail-to-rail output capability
• Slew rate of 0.42 V/µs
• Gain bandwidth product of 1.5 MHz
• Input bias current within 14–15 nA range
• Input offset voltage of 1 mV
• Supply current of 116 µA across both channels
• Output current per channel of 100 mA
• Supply voltage range from 1.8 V to 5 V
• Operating temperature range of -40°C to 125°C

Mechanical Parameter Equivalence:

• Surface mount technology
• 10-VSSOP package configuration
• 10-TFSOP, 10-MSOP physical footprint (0.118", 3.00mm width)

Compliance and Status Equivalence:

• ROHS3 compliance
• MSL Level 1 (unlimited moisture sensitivity)
• Active product status (for substitute parts)

The substitute parts LMV982MM/NOPB and LMV982MMX/NOPB meet all specified electrical and mechanical requirements and are manufactured by the same supplier (Texas Instruments) under the same LMV® series designation.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LMV982MM/NOPB

The LMV982MM/NOPB is the manufacturer-recommended substitute for the obsolete LMV982IDGSR. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain continuity. Inventory availability of 31,199 units supports production requirements. The packaging format (Tape & Reel) is standard for high-volume manufacturing operations. All electrical parameters, mechanical specifications, and compliance certifications (ROHS3, REACH Unaffected, EAR99) are identical to the main part. Input bias current is marginally lower at 14 nA compared to 15 nA, representing improved performance within acceptable tolerance.

Secondary Substitute: LMV982MMX/NOPB

The LMV982MMX/NOPB provides an alternative substitute with identical electrical and mechanical specifications. This part also maintains active product status and meets all compliance requirements. Inventory availability of 1,900 units is lower than the primary substitute. Selection of this part is appropriate when primary substitute availability is constrained or when specific procurement agreements favor this variant designation.

Compliance and Regulatory Basis:

Both substitute parts satisfy ROHS3 compliance requirements, REACH regulatory status (unaffected), and export control classifications (EAR99). Moisture sensitivity level remains at MSL 1 (unlimited), eliminating special handling requirements. These factors support direct substitution without design modification or additional qualification testing.

Frequently Asked Questions (FAQ)

Q1: Can LMV982MM/NOPB and LMV982MMX/NOPB be used interchangeably with LMV982IDGSR?

A: Yes. Both substitute parts are electrically and mechanically equivalent to the LMV982IDGSR. All critical parameters—including slew rate, gain bandwidth product, supply voltage range, operating temperature, and package configuration—are identical. The parts are pin-compatible and footprint-compatible for direct PCB substitution.

Q2: What is the difference between LMV982MM/NOPB and LMV982MMX/NOPB?

A: Both parts are functionally equivalent with identical electrical specifications and package configurations. The difference lies in the part number suffix designation (MM versus MMX) and inventory availability. LMV982MM/NOPB has higher stock levels (31,199 units) compared to LMV982MMX/NOPB (1,900 units). Selection should be based on procurement availability and supply chain requirements.

Q3: Why is the LMV982IDGSR classified as obsolete?

A: The LMV982IDGSR has been discontinued by Texas Instruments. The manufacturer recommends transitioning to active alternatives (LMV982MM/NOPB or LMV982MMX/NOPB) to ensure ongoing supply availability and support. Obsolete status does not indicate functional deficiency but rather production discontinuation.

Q4: Are there any performance differences between the main part and substitute parts?

A: Input bias current is marginally lower in the substitute parts (14 nA versus 15 nA in the main part), representing improved performance. All other electrical parameters—slew rate, gain bandwidth product, input offset voltage, supply current, output current, and operating temperature range—are identical. These differences are within normal manufacturing tolerance and do not affect circuit functionality.

Q5: What packaging format is used for the substitute parts?

A: Both LMV982MM/NOPB and LMV982MMX/NOPB are supplied in Tape & Reel (TR) format, which is standard for automated assembly operations. The physical package remains 10-VSSOP with 10-TFSOP, 10-MSOP footprint (0.118", 3.00mm width), ensuring compatibility with existing PCB designs.

Q6: Do the substitute parts require different handling or storage procedures?

A: No. Both substitute parts maintain MSL Level 1 (unlimited moisture sensitivity), identical to the main part. Standard handling and storage procedures for surface mount components apply without modification.

Q7: Are the substitute parts compliant with current regulatory requirements?

A: Yes. Both LMV982MM/NOPB and LMV982MMX/NOPB are ROHS3 compliant, REACH unaffected, and classified under EAR99 export control. These certifications match the main part and satisfy current regulatory requirements for electronic component procurement.

Q8: Can existing designs using LMV982IDGSR be updated to use substitute parts without PCB redesign?

A: Yes. The substitute parts are pin-compatible and footprint-compatible with the LMV982IDGSR. No PCB layout modifications are required. Direct component substitution is supported for existing designs.
