Supply range is 1.8V to 5V with -40°C to 85°C operating temperature. Package is 8-SOP format. Supply current is 140µA with 90mA output current per channel. This device is ROHS3 compliant and active, suitable for applications where lower bandwidth is acceptable and extended low-voltage operation (1.8V minimum) is required.

Frequently Asked Questions (FAQ)

Q1: Can LMV772MA/NOPB be used as a direct drop-in replacement for LMV772MA?

A: Yes. LMV772MA/NOPB is the direct equivalent with identical electrical specifications, dual-circuit configuration, and 8-SOIC package dimensions. The primary differences are active product status and ROHS3 compliance. No circuit modifications are required for substitution.

Q2: What are the key differences between LMV772MA and ADA4891-2ARZ?

A: The ADA4891-2ARZ offers significantly higher performance: slew rate of 210V/µs versus 1.4V/µs, and gain bandwidth product of 105 MHz versus 3.5 MHz. Both maintain identical supply voltage range (2.7V to 5.5V) and operating temperature (-40°C to 125°C). The ADA4891-2ARZ is a CMOS device with lower input bias current (2 pA versus 0.23 pA) but higher input offset voltage (2.5 mV versus 250 µV). Both are 8-SOIC packaged and ROHS3 compliant. The ADA4891-2ARZ is suitable for applications requiring higher bandwidth and faster transient response.

Q3: Are the 8-SOP packaged alternatives (BU7266, BU7486) mechanically compatible with LMV772MA?

A: The 8-SOP package (0.173", 4.40mm width) differs from the LMV772MA 8-SOIC package (0.154", 3.90mm width). While both are 8-pin surface-mount packages with similar pin spacing, the physical dimensions are different. PCB footprints are not interchangeable without layout modification. Verify footprint compatibility before selecting these alternatives.

Q4: Which substitute part is recommended for automotive applications?

A: LMV822AIDT and LMV822IDT are qualified to AEC-Q100 automotive standards. Both maintain 8-SOIC package compatibility with the LMV772MA and offer comparable performance (1.9V/µs slew rate, 5.5 MHz gain bandwidth product). These devices are suitable for automotive and industrial applications requiring automotive-grade qualification.

Q5: What is the primary advantage of BU7266F-E2 and BU7266SF-E2 over LMV772MA?

A: The primary advantage is ultra-low supply current consumption (700nA versus 600µA). These devices are designed for power-constrained applications. However, they offer significantly reduced bandwidth (4 kHz gain bandwidth product versus 3.5 MHz) and lower output current capability (4 mA versus 75 mA). Selection depends on application requirements for power consumption versus bandwidth.

Q6: Can LMV772MA be substituted in applications requiring extended temperature operation above 125°C?

A: No. The LMV772MA and all listed substitute parts are rated to maximum 125°C (except BU7266F-E2 and LMR932F-GE2 which are limited to 85°C). For applications requiring extended temperature operation, alternative device families must be evaluated outside this substitute list.

Q7: What packaging options are available for the ADA4891-2ARZ?

A: Three packaging variants are available: ADA4891-2ARZ (tube packaging, 2155 pcs inventory), ADA4891-2ARZ-R7 (cut tape & digi-reel, 15300 pcs inventory), and ADA4891-2ARZ-RL (tape & reel, 5320 pcs inventory). All variants have identical electrical specifications. Selection depends on procurement method and assembly equipment compatibility.

Q8: Is RoHS compliance a factor in selecting substitutes for LMV772MA?

A: Yes. The original LMV772MA is RoHS non-compliant. All active substitute parts listed are ROHS3 compliant. For new designs and production requiring RoHS compliance, LMV772MA/NOPB or any of the active alternatives are suitable. For legacy systems where RoHS compliance is not required, the original LMV772MA may remain acceptable if inventory is available.

Q9: What is the minimum supply voltage requirement for each substitute part?

A: LMV772MA and most alternatives operate at 2.7V minimum. LMV822AIDT and LMV822IDT require 2.5V minimum. BU7266F-E2 and BU7266SF-E2 operate at 1.8V minimum, providing extended low-voltage capability. BU7486F-E2 requires 3V minimum supply voltage. Verify minimum supply voltage compatibility with your application before selection.

Q10: Are there performance trade-offs when selecting lower-cost alternatives?

A: Yes. Lower-cost alternatives typically involve trade-offs in bandwidth, slew rate, or supply current. For example, BU7266 series offers ultra-low power consumption but reduced bandwidth (4 kHz). LMR932F-GE2 offers lower performance (0.35V/µs slew rate, 1.4 MHz bandwidth) but extended low-voltage operation. Evaluate application requirements for bandwidth, transient response, and power consumption before selecting alternatives based on cost considerations.
