Substitute Part Grouping Explanation
Substitution of the LMP7716MM is determined by the following critical parameters:
Primary Substitution Criteria:
- Dual-circuit configuration (2 circuits required)
- Rail-to-rail output capability
- Surface mount packaging (8-VSSOP or 8-MSOP compatible)
- Supply voltage range: 1.8V to 5.5V minimum overlap
- Operating temperature range: minimum -40°C to 125°C coverage
- Active product status for long-term availability
Secondary Performance Considerations:
- Slew rate ≥ 11.5V/µs (for direct performance equivalence)
- Gain bandwidth product ≥ 17 MHz (for direct performance equivalence)
- Input bias current ≤ 0.1 pA (for direct performance equivalence)
- Output current per channel ≥ 66 mA (for direct performance equivalence)
The substitute parts are grouped into two categories:
Category 1: Direct Equivalents (Identical Electrical Performance)
- LMP7716MM/NOPB: Identical specifications with active product status and RoHS3 compliance
Category 2: Functional Alternatives (Different Electrical Performance)
- Parts with reduced slew rate, bandwidth, or output current but maintaining dual-circuit, rail-to-rail, surface mount configuration and compatible supply voltage range

Engineering Selection Recommendations
Direct Replacement (Identical Performance):
LMP7716MM/NOPB is the direct equivalent of LMP7716MM. This part maintains identical electrical specifications including slew rate, gain bandwidth product, input bias current, and output current. The primary distinction is product status transition from obsolete to active, ensuring continued availability and supply chain support. LMP7716MM/NOPB carries RoHS3 compliance, addressing regulatory requirements for new designs and manufacturing processes.
Performance-Equivalent Alternatives (Active Status, RoHS3 Compliant):
NCS20032DMR2G (onsemi) provides general purpose amplifier functionality with slew rate of 8V/µs and 7 MHz gain bandwidth product, representing 70% and 41% of the LMP7716MM specifications respectively. Output current per channel reaches 96 mA, exceeding the original 66 mA. This part maintains the full -40°C to 125°C operating range and supports 1.7V to 5.5V supply voltage.
OA2MPA34S (STMicroelectronics) is a CMOS amplifier with 0.06V/µs slew rate and 150 kHz gain bandwidth product. Output current per channel is 56 mA. This part supports -40°C to 125°C operating temperature and 1.5V to 5.5V supply voltage range, providing extended low-voltage capability.
Low-Power Alternatives (Reduced Performance, Active Status, RoHS3 Compliant):
MCP6422T-E/MS (Microchip Technology) delivers ultra-low supply current of 4.4µA across both channels, suitable for battery-powered applications. Slew rate is 0.05V/µs and gain bandwidth product is 90 kHz. Output current per channel is 22 mA. Full -40°C to 125°C temperature range is supported.
OA2NP34S (STMicroelectronics) is optimized for ultra-low power consumption at 650nA supply current. Operating temperature range is -40°C to 85°C, which does not extend to the full 125°C upper limit of the original part.
Limited-Performance Alternatives (Reduced Specifications, Active Status, RoHS3 Compliant):
BU7266FVM-TR and BU7266SFVM-TR (Rohm Semiconductor) are CMOS amplifiers with significantly reduced slew rate (0.0024V/µs) and gain bandwidth product (4 kHz).

A: LMP7716MM/NOPB, MCP6422-E/MS, MCP6422T-E/MS, NCS20032DMR2G, NCV20032DMR2G, and OA2MPA34S all support -40°C to 125°C operation. BU7266FVM-TR, BU7266SFVM-TR, BU7486FVM-TR, and OA2NP34S have reduced upper temperature limits.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed carry RoHS3 compliance status. The original LMP7716MM is RoHS non-compliant. Transition to any substitute part addresses regulatory compliance requirements.
Q: Which substitute provides the lowest supply current consumption?
A: OA2NP34S delivers the lowest supply current at 650nA across both channels, followed by BU7266FVM-TR and BU7266SFVM-TR at 700nA. These parts are optimized for battery-powered and ultra-low-power applications.
Q: Can MCP6422T-E/MS replace LMP7716MM in high-speed applications?
A: No. MCP6422T-E/MS has slew rate of 0.05V/µs and gain bandwidth product of 90 kHz, compared to LMP7716MM specifications of 11.5V/µs and 17 MHz. This part is suitable only for low-frequency signal processing applications.
Q: What is the supply voltage compatibility range across all substitute parts?
A: All substitute parts support minimum 1.5V to 1.8V and maximum 5.5V supply voltage. The LMP7716MM specifies 1.8V to 5.5V. OA2MPA34S and OA2NP34S extend minimum voltage to 1.5V, providing enhanced low-voltage capability. BU7486FVM-TR requires minimum 3V supply voltage.
