Substitute Part Grouping Explanation

Substitution of the LMP7716MMX is determined by the following critical parameters:

Electrical Compatibility Criteria:

Dual-circuit configuration (2 circuits required)
Rail-to-rail output capability
Supply voltage range: 1.8 V to 5.5 V minimum overlap
Operating temperature range: minimum -40°C to 125°C
Surface-mount package format

Mechanical Compatibility Criteria:

8-pin package footprint (8-VSSOP, 8-MSOP, or 8-MiniSO)
Pin-compatible or functionally equivalent pinout

Substitute parts are grouped into two categories based on performance characteristics:

Category 1: Direct Functional Equivalents Parts maintaining similar slew rate (≥8 V/µs) and gain-bandwidth product (≥7 MHz) performance levels, suitable for applications requiring comparable dynamic response.

Category 2: Low-Power Alternatives Parts with reduced supply current consumption (<10 µA) and lower slew rate (<1 V/µs), appropriate for power-constrained applications where the LMP7716MMX performance envelope exceeds requirements.

Engineering Selection Recommendations

Primary Substitute: LMP7716MMX/NOPB

The LMP7716MMX/NOPB is the direct equivalent of the obsolete LMP7716MMX. This part maintains identical electrical specifications, including 11.5 V/µs slew rate, 17 MHz gain-bandwidth product, and 66 mA output current per channel. The LMP7716MMX/NOPB is classified as Active product status with ROHS3 compliance, making it the preferred choice for design continuity and regulatory compliance. Packaging is Tape & Reel (TR) format with 35,200 units in stock.

Secondary Substitute: NCV20032DMR2G (onsemi)

The NCV20032DMR2G provides general-purpose amplifier functionality with 8 V/µs slew rate and 7 MHz gain-bandwidth product, meeting the -40°C to 125°C operating temperature requirement. This part delivers 14 mA output current per channel and operates across the 1.7 V to 5.5 V supply range. Product status is Active with ROHS3 compliance. This substitute is suitable for applications where the LMP7716MMX performance envelope exceeds system requirements.

Tertiary Substitute: BU7486FVM-TR (Rohm Semiconductor)

The BU7486FVM-TR is a CMOS amplifier with 10 V/µs slew rate and 10 MHz gain-bandwidth product, providing performance comparable to the LMP7716MMX in dynamic response. Operating temperature range is -40°C to 105°C. This part requires minimum 3 V supply voltage, which may limit applicability in ultra-low-voltage designs. Product status is Active with ROHS3 compliance.

Low-Power Alternative: OA2NP34S (STMicroelectronics)

The OA2NP34S is a CMOS amplifier optimized for power-constrained applications, with supply current of 650 nA per channel. Operating temperature range is -40°C to 85°C, which does not extend to 125°C. This part is suitable only for applications where the upper temperature limit of 85°C is acceptable and power consumption is a primary design constraint.

Frequently Asked Questions (FAQ)

Q1: Can the LMP7716MMX/NOPB be used as a direct replacement for the LMP7716MMX?

A: Yes. The LMP7716MMX/NOPB is electrically and mechanically identical to the LMP7716MMX. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. Non-compliant). Pin configuration, package footprint, and all electrical parameters are identical. This is the recommended substitute for design continuity.

Q2: What are the key differences between the LMP7716MMX and the NCV20032DMR2G?

A: The NCV20032DMR2G has lower slew rate (8 V/µs vs. 11.5 V/µs) and lower gain-bandwidth product (7 MHz vs. 17 MHz). Output current per channel is also reduced (14 mA vs. 66 mA). The NCV20032DMR2G is suitable for applications where these performance reductions are acceptable and where the extended -40°C to 125°C temperature range is required.

Q3: Why do some substitute parts have lower operating temperature maximums?

A: The BU7266FVM-TR and OA2NP34S are specified to -40°C to 85°C maximum, compared to the LMP7716MMX specification of -40°C to 125°C. These parts are not suitable for applications requiring operation above 85°C. Verify application temperature requirements before selection.

Q4: What is the significance of the 1.8 V minimum supply voltage specification?

A: The LMP7716MMX operates with a minimum supply voltage of 1.8 V. The BU7486FVM-TR requires a minimum of 3 V supply voltage. Applications operating below 3 V cannot use the BU7486FVM-TR. Verify supply voltage availability in your design before part selection.

Q5: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original LMP7716MMX is RoHS non-compliant. If RoHS compliance is a regulatory requirement, the LMP7716MMX/NOPB or any other listed substitute must be used.

Q6: What is the difference between 8-VSSOP, 8-MSOP, and 8-MiniSO packages?

A: These are all 8-pin surface-mount packages with different physical dimensions. The 8-VSSOP is 0.118" width (3.00mm), 8-MSOP is 0.118" width (3.00mm), and 8-MiniSO is also 0.118" width (3.00mm). All listed substitutes are compatible with PCB layouts designed for the LMP7716MMX 8-VSSOP package footprint.

Q7: Can the MCP6422T-E/MS be used in high-speed applications?

A: No. The MCP6422T-E/MS has a gain-bandwidth product of only 90 kHz and slew rate of 0.05 V/µs, compared to the LMP7716MMX specifications of 17 MHz and 11.5 V/µs. This part is suitable only for low-frequency, low-speed signal conditioning applications.

Q8: What inventory levels are available for each substitute part?

A: LMP7716MMX/NOPB: 35,200 units; NCV20032DMR2G: 1,540 units; BU7486FVM-TR: 4,095 units; BU7266FVM-TR: 5,787 units; OA2NP34S: 100,200 units; MCP6422T-E/MS: 3,621 units. Verify current availability with your supplier before committing to production quantities.
