Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMV794MM/NOPB is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Dual-circuit configuration (2 circuits required)
• Rail-to-rail output capability
• Operating temperature range: -40°C to 125°C
• Supply voltage span compatibility: minimum 2V to maximum 5.5V
• Surface-mount package format with 8-pin configuration

Mechanical Compatibility Criteria:

• Package type: 8-MSOP or 8-TSSOP footprint (0.118", 3.00mm width)
• Mounting type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Regulatory Compliance:

• RoHS3 Compliant status
• REACH Unaffected status

The substitute parts identified below meet these core compatibility requirements. Variations in secondary parameters such as slew rate, gain bandwidth product, input bias current, and supply current are within acceptable ranges for general-purpose amplifier applications and do not preclude functional substitution.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full RoHS3 compliance, ensuring regulatory alignment with the LMV794MM/NOPB. The following selection criteria apply:

LTC6244HMS8#PBF (Analog Devices Inc.): This substitute is classified as a CMOS amplifier with identical slew rate (35V/µs) and input offset voltage (100µV) to the LMV794MM/NOPB. The device operates within the required temperature range and maintains rail-to-rail output capability. The minimum supply voltage is 2.8V, which is higher than the LMV794MM/NOPB minimum of 2V. This part is supplied in tube packaging with 8-MSOP configuration.

MCP662-E/MS (Microchip Technology): This general-purpose amplifier substitute provides 60MHz gain bandwidth product and 90mA output current per channel, exceeding the LMV794MM/NOPB output current specification of 60mA. The slew rate is 32V/µs, marginally lower than the primary part. Supply voltage span is 2.5V to 5.5V. This part is supplied in tube packaging with 8-MSOP configuration.

MCP662T-E/MS (Microchip Technology): This variant of the MCP662 is electrically identical to MCP662-E/MS but is supplied in cut tape and Digi-Reel packaging format. All electrical parameters and compliance certifications remain equivalent. This packaging option provides alternative distribution flexibility.

All substitute parts are suitable for direct component selection based on inventory availability, packaging preference, and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the LTC6244HMS8#PBF be used as a direct replacement for the LMV794MM/NOPB?

A: The LTC6244HMS8#PBF is electrically compatible for general-purpose dual-amplifier applications. Both devices feature 2 circuits, rail-to-rail output, identical slew rate (35V/µs), and identical input offset voltage (100µV). The primary difference is the minimum supply voltage: LTC6244HMS8#PBF requires 2.8V minimum versus 2V for the LMV794MM/NOPB. Verify that your application supply voltage meets the 2.8V minimum requirement before substitution.

Q: What is the difference between MCP662-E/MS and MCP662T-E/MS?

A: MCP662-E/MS and MCP662T-E/MS are electrically identical devices. The difference is packaging format: MCP662-E/MS is supplied in tube packaging, while MCP662T-E/MS is supplied in cut tape and Digi-Reel format. Both use 8-MSOP package configuration and meet all electrical and compliance specifications identically.

Q: Are all substitute parts pin-compatible with the LMV794MM/NOPB?

A: All substitute parts use 8-pin MSOP or VSSOP package configurations with 0.118" (3.00mm) width. While the physical footprint is compatible, verify pinout assignment in the respective device datasheets to confirm functional pin compatibility for your specific circuit design.

Q: Do all substitute parts meet the same temperature operating range?

A: Yes. The LMV794MM/NOPB and all identified substitute parts operate across the -40°C to 125°C temperature range, ensuring thermal compatibility for equivalent applications.

Q: What are the key electrical differences between these substitute parts?

A: The LMV794MM/NOPB features the lowest input bias current (0.1pA) and lowest supply current (1.3mA for dual channels). The MCP662 variants provide higher output current capability (90mA per channel versus 60mA). The LTC6244HMS8#PBF offers identical slew rate and input offset voltage but requires higher minimum supply voltage (2.8V). Select based on your specific application requirements for output current, input bias current, and minimum supply voltage.

Q: Are all parts RoHS3 compliant?

A: Yes. The LMV794MM/NOPB and all substitute parts are RoHS3 compliant with moisture sensitivity level 1 (unlimited), ensuring regulatory compliance and environmental compatibility.
