Engineering Selection Recommendations

For Direct Replacement (Lowest Risk): Select LPV358MM/NOPB or LPV358MMX/NOPB when the original LPV358DGKR specifications must be maintained exactly. Both parts are active products with identical electrical performance and RoHS3 compliance. The choice between MM and MMX variants depends on packaging format requirements: MM is supplied in Tape & Reel format, while MMX is available in Cut Tape & Digi-Reel packaging.

For Enhanced Performance with Extended Temperature Range: Select LMV358MM/NOPB or LMV358MMX/NOPB when applications can tolerate increased supply current (210 µA versus 15 µA per channel pair) in exchange for improved dynamic performance. These parts provide 10× higher gain bandwidth product (1 MHz versus 237 kHz) and extended operating temperature to 125°C. Both are active products with ROHS3 compliance and identical package specifications.

For Differential Output Applications: Select LMV716MM/NOPB when differential signal processing is required. This active part maintains 8-VSSOP package compatibility while providing differential output capability, 5.8 V/µs slew rate, and 5 MHz bandwidth. Operating temperature range matches the original part (-40°C to 85°C).

For Ultra-Low Power Battery Applications: Select BU7266FVM-TR or BU7266SFVM-TR when supply current minimization is critical. These Rohm CMOS parts consume only 700 nA total supply current. BU7266SFVM-TR extends operating temperature to 105°C. Both maintain 8-MSOP package compatibility and ROHS3 compliance. Note: Significantly reduced output current (4 mA) and gain bandwidth product (4 kHz) limit application scope.

For High-Speed Applications: Select BU7486FVM-TR when 10 V/µs slew rate and 10 MHz bandwidth are required. This Rohm part maintains 8-MSOP package compatibility and ROHS3 compliance with extended temperature range to 105°C. Supply current increases to 6 mA.

Frequently Asked Questions (FAQ)

Q: Can LPV358MM/NOPB directly replace LPV358DGKR in existing designs?

A: Yes. LPV358MM/NOPB maintains identical electrical specifications including 0.1 V/µs slew rate, 2 nA input bias current, and 2.7 V to 5 V supply range. Both use 8-VSSOP packaging with identical pinout. The primary difference is product status: LPV358DGKR is obsolete while LPV358MM/NOPB is active. Packaging format differs (Tape & Reel versus original format), but electrical performance is equivalent.

Q: What is the key difference between LMV358 and LPV358 series?

A: LMV358 provides enhanced performance with 1 V/µs slew rate and 1 MHz gain bandwidth product compared to LPV358's 0.1 V/µs and 237 kHz. LMV358 extends operating temperature to 125°C and increases supply current to 210 µA per channel pair. Both maintain 8-VSSOP package compatibility and rail-to-rail output. LMV358 is suitable for applications requiring faster signal processing.

Q: Are Rohm BU7266 and BU7486 parts compatible with the original LPV358DGKR package?

A: Both Rohm parts use 8-MSOP packaging, which is mechanically compatible with 8-VSSOP in terms of pin count and pitch (0.118" width). However, electrical characteristics differ significantly. BU7266 features ultra-low supply current (700 nA) but reduced output current (4 mA) and bandwidth (4 kHz). BU7486 provides higher performance (10 V/µs, 10 MHz) but increased supply current (6 mA). Substitution requires application-specific evaluation.

Q: What is the advantage of AD8617WARMZ-REEL over LPV358 variants?

A: AD8617WARMZ-REEL is a CMOS amplifier offering ultra-low input bias current (0.2 pA versus 2 nA), superior input offset voltage (400 µV versus 1.5 mV), and extended temperature range to 125°C. It maintains 8-MSOP package compatibility and provides 400 kHz gain bandwidth product. Supply current is 38 µA. This part is suitable for high-impedance input applications and extended temperature environments.

Q: Can LMV716MM/NOPB be used in place of LPV358DGKR?

A: LMV716MM/NOPB provides differential output capability and significantly enhanced performance (5.8 V/µs slew rate, 5 MHz bandwidth) while maintaining 8-VSSOP package compatibility and -40°C to 85°C operating range. However, differential output configuration differs from the single-ended rail-to-rail output of LPV358DGKR. Substitution is valid only for applications requiring or tolerating differential output topology.

Q: What packaging formats are available for LPV358 and LMV358 substitutes?

A: LPV358MM/NOPB and LMV358MM/NOPB are supplied in Tape & Reel (TR) format. LPV358MMX/NOPB and LMV358MMX/NOPB are supplied in Cut Tape (CT) & Digi-Reel format. Both formats use identical 8-VSSOP packages with equivalent electrical specifications. Selection depends on production equipment compatibility and inventory management requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—LPV358MM/NOPB, LPV358MMX/NOPB, LMV358MM/NOPB, LMV358MMX/NOPB, LMV716MM/NOPB, AD8617WARMZ-REEL, BU7266FVM-TR, BU7266SFVM-TR, and BU7486FVM-TR—are ROHS3 compliant and REACH unaffected, matching the compliance status of the original LPV358DGKR.

Q: Which substitute provides the best performance-to-power-consumption ratio?

A: LMV358MM/NOPB or LMV358MMX/NOPB offer balanced performance with 1 MHz bandwidth and 210 µA supply current per channel pair. For ultra-low power applications, BU7266FVM-TR consumes only 700 nA but provides minimal bandwidth (4 kHz). For high-speed applications, BU7486FVM-TR delivers 10 MHz bandwidth at 6 mA supply current. Selection depends on specific application requirements.
