Substitute Part Grouping Explanation
Substitution of the AD8692ARMZ-R2 is determined by the following critical parameters: dual-circuit general-purpose amplifier topology, rail-to-rail output configuration, 10 MHz gain bandwidth product, 5 V/µs slew rate, 2.7 V to 6 V supply voltage range, surface mount packaging in 8-pin MSOP or VSSOP form factor, and operating temperature range of -40°C to 125°C.
Substitute parts are grouped into two categories:
Direct Equivalent: The AD8692ARMZ-REEL maintains identical electrical specifications and package form factor, differing only in product status (Active vs. Obsolete) and packaging configuration (Digi-Reel vs. standard tape).
Functional Equivalents: Parts including the LMV652 series (LMV652MM/NOPB, LMV652MMX/NOPB), LMV722 series (LMV722IDGKR, LMV722MM/NOPB, LMV722MMX/NOPB, LMV722QDGKRQ1), LMV797MM/NOPB, and MCP6292 series (MCP6292-E/MS, MCP6292T-E/MS) satisfy the core functional requirements of dual-circuit, rail-to-rail general-purpose amplification within compatible supply voltage and temperature ranges. These parts exhibit variations in slew rate, gain bandwidth product, input bias current, and supply current that remain within acceptable operational parameters for most applications requiring the AD8692ARMZ-R2 baseline performance.

Engineering Selection Recommendations
Direct Replacement: The AD8692ARMZ-REEL is the primary recommended substitute, offering identical electrical performance and package compatibility. This part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory alignment.
Supply Voltage Compatibility: All listed substitutes operate within the 2.7 V to 6 V supply range of the AD8692ARMZ-R2. The LMV797MM/NOPB extends the minimum supply voltage to 1.8 V, providing additional design flexibility for ultra-low-voltage applications.
Temperature Range Considerations: The LMV652 series and LMV722QDGKRQ1 maintain the full -40°C to 125°C operating range. The LMV722MM/NOPB and LMV722MMX/NOPB are limited to -40°C to 85°C. The LMV722IDGKR operates from -45°C to 105°C. Application requirements must dictate temperature range selection.
Automotive Grade Option: The LMV722QDGKRQ1 carries AEC-Q100 automotive qualification with MSL 2 rating, suitable for automotive and industrial applications requiring enhanced reliability certification.
Package Form Factor: The MCP6292-E/MS and MCP6292T-E/MS maintain the 8-MSOP package identical to the AD8692ARMZ-R2. All other substitutes utilize 8-VSSOP packaging, which is mechanically compatible within the same 0.118" (3.00mm) width specification but requires PCB layout verification for pin-to-pin compatibility.
Compliance Status: All active substitutes carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.
Frequently Asked Questions (FAQ)
Q: Can the AD8692ARMZ-REEL be used as a direct replacement for the AD8692ARMZ-R2?
A: Yes. The AD8692ARMZ-REEL is electrically and functionally identical to the AD8692ARMZ-R2, with differences limited to product status (Active vs. Obsolete) and packaging configuration (Digi-Reel vs. standard tape). Pin configuration, electrical specifications, and package dimensions are identical.
Q: What is the primary difference between the LMV652 and LMV722 series substitutes?
A: The LMV652 series (LMV652MM/NOPB, LMV652MMX/NOPB) features a 12 MHz gain bandwidth product with 3 V/µs slew rate and significantly lower supply current (118 µA). The LMV722 series maintains the 10 MHz gain bandwidth product with 5.25 V/µs slew rate and higher supply current (1.81 to 2.01 mA). Selection depends on bandwidth and power consumption requirements.
Q: Are the 8-VSSOP and 8-MSOP packages interchangeable on the same PCB?
A: Both packages share identical 0.118" (3.00mm) width and 8-pin configuration. However, pin pitch and lead geometry differ between MSOP and VSSOP variants. PCB footprint verification is required before substitution. The packages are not directly interchangeable without PCB redesign.
Q: Which substitute offers the lowest power consumption?
A: The LMV652 series provides the lowest supply current at 118 µA (x2 channels), approximately 8 times lower than the AD8692ARMZ-R2 at 950 µA. This makes the LMV652MM/NOPB or LMV652MMX/NOPB optimal for battery-powered or ultra-low-power applications.
Q: Does the MCP6292 series maintain the same input bias current as the AD8692ARMZ-R2?
A: Yes. Both the MCP6292-E/MS and MCP6292T-E/MS feature 1 pA input bias current, matching the AD8692ARMZ-R2 specification. However, the MCP6292 series exhibits higher input offset voltage (3 mV vs. 400 µV), which may impact precision analog applications.
Q: What is the significance of the LMV722QDGKRQ1 automotive qualification?
A: The LMV722QDGKRQ1 carries AEC-Q100 automotive qualification, indicating compliance with automotive reliability and environmental stress testing standards. This part is suitable for automotive, industrial, and mission-critical applications requiring enhanced qualification documentation.
Q: Can the LMV797MM/NOPB be used in applications requiring the full -40°C to 125°C temperature range?
A: Yes. The LMV797MM/NOPB operates across the full -40°C to 125°C range and additionally extends the minimum supply voltage to 1.8 V. However, this part features higher gain bandwidth product (17 MHz) and slew rate (11.5 V/µs), which may introduce different frequency response characteristics in the application circuit.
Q: What packaging options are available for the AD8692 base product?
A: The AD8692ARMZ-REEL is available in Cut Tape (CT) and Digi-Reel packaging configurations. Both maintain identical electrical specifications and 8-MSOP package form factor, with selection based on procurement and assembly process requirements.
