Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMV825AIPT is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier type (General Purpose)
• Number of circuits (4 independent channels)
• Output type (Rail-to-Rail)
• Slew rate (1.9 V/µs)
• Gain bandwidth product (5.5 MHz)
• Input bias current (60 nA)
• Input offset voltage (800 µV)
• Supply current per channel (300 µA total for 4 channels)
• Output current per channel (70 mA)
• Supply voltage range (2.5 V to 5.5 V)
• Operating temperature range (-40°C to 125°C)

Mechanical and Compliance Criteria:

• Automotive grade qualification (AEC-Q100)
• Surface-mount technology
• TSSOP package family
• RoHS3 compliance
• MSL rating (1 - Unlimited)

The LMV824AIPT qualifies as a substitute based on matching all electrical performance parameters and automotive-grade certifications. The primary distinction is the package configuration: the LMV824AIPT uses a 14-TSSOP package versus the 16-TSSOP of the LMV825AIPT. Both packages maintain the same 4.40mm width and surface-mount compatibility.

Parameter Comparison

Engineering Selection Recommendations

The LMV824AIPT is a direct electrical substitute for the LMV825AIPT. Both devices share identical electrical specifications, automotive-grade qualification (AEC-Q100), and compliance certifications (ROHS3, REACH Unaffected).

The LMV824AIPT holds Active product status, ensuring ongoing availability and manufacturing support, whereas the LMV825AIPT is classified as Obsolete. This status difference makes the LMV824AIPT the preferred selection for new designs and ongoing production requirements.

The primary design consideration is the package transition from 16-TSSOP to 14-TSSOP. Both packages maintain identical width (4.40mm) and surface-mount compatibility. PCB layout modifications may be required to accommodate the reduced pin count and physical footprint of the 14-TSSOP package. Pin-to-pin functional mapping must be verified during circuit redesign to ensure proper signal routing and power distribution.

Frequently Asked Questions (FAQ)

Q: Can the LMV824AIPT directly replace the LMV825AIPT without circuit modifications?

A: The LMV824AIPT provides identical electrical performance and automotive-grade certification. However, the package change from 16-TSSOP to 14-TSSOP requires PCB layout redesign. Pin assignments differ between the two packages, necessitating schematic and layout verification before implementation.

Q: What is the difference between the 16-TSSOP and 14-TSSOP packages?

A: Both packages maintain the same 4.40mm width and surface-mount technology. The 16-TSSOP contains 16 pins, while the 14-TSSOP contains 14 pins. The functional difference relates to pin configuration and spacing. Detailed pinout documentation must be consulted for each package variant.

Q: Are both parts automotive-grade qualified?

A: Yes. Both the LMV825AIPT and LMV824AIPT carry automotive-grade classification with AEC-Q100 qualification, meeting automotive industry reliability and quality standards.

Q: What is the significance of the LMV825AIPT being Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The LMV824AIPT, with Active status, represents the current production alternative and ensures long-term supply chain continuity.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both devices are ROHS3 compliant, REACH Unaffected, and carry MSL rating 1 (Unlimited moisture sensitivity level). Compliance certifications are identical across both part numbers.

Q: What are the electrical performance specifications that remain constant between these parts?

A: Slew rate (1.9 V/µs), gain bandwidth product (5.5 MHz), input bias current (60 nA), input offset voltage (800 µV), supply current (300 µA for 4 channels), output current per channel (70 mA), and supply voltage range (2.5 V to 5.5 V) are identical. Operating temperature range (-40°C to 125°C) is also unchanged.

Q: Is PCB redesign mandatory when switching from LMV825AIPT to LMV824AIPT?

A: Yes. The package transition requires PCB footprint modification and pin reassignment. Schematic verification and layout redesign are mandatory to ensure correct signal routing, power distribution, and ground connectivity.
