Engineering Selection Recommendations

Direct Replacement (Identical Package and Pinout):

The LMV772MAX/NOPB represents the direct active equivalent of the obsolete LMV772MAX. This part maintains identical electrical specifications, package dimensions (8-SOIC, 3.90mm width), and pinout configuration. The primary distinction is product status: LMV772MAX/NOPB is active and RoHS3 compliant, whereas the original LMV772MAX is obsolete and RoHS non-compliant. For applications requiring exact form-factor compatibility and no PCB redesign, LMV772MAX/NOPB is the recommended selection.

Performance-Matched Alternatives (8-SOIC Package):

The ADA4692-2ARZ and ADA4692-2ARZ-RL (Analog Devices) maintain the 8-SOIC package footprint with compatible dual-circuit, rail-to-rail architecture. These parts operate within the LMV772MAX supply voltage range (2.7V to 5V) and temperature specification (-40°C to 125°C). Electrical performance is comparable: slew rate of 1.3V/µs versus 1.4V/µs, and gain bandwidth product of 3.6 MHz versus 3.5 MHz. Input bias current is higher (0.5 pA versus 0.23 pA) and input offset voltage is doubled (500 µV versus 250 µV). Supply current is significantly lower (180 µA versus 600 µA per channel), reducing power consumption. Both variants are active and RoHS3 compliant. Selection between tube (ADA4692-2ARZ) and tape-and-reel (ADA4692-2ARZ-RL) packaging depends on production volume and handling requirements.

High-Performance Alternatives (8-SOIC Package):

The ADA4891-2ARZ, ADA4891-2ARZ-R7, and ADA4891-2ARZ-RL (Analog Devices) provide significantly enhanced performance in the 8-SOIC package. These CMOS amplifiers deliver slew rate of 210V/µs (150× faster), gain bandwidth product of 105 MHz (30× higher), and output current of 125 mA (67% higher) compared to the LMV772MAX. Supply voltage range (2.7V to 5.5V) and operating temperature (-40°C to 125°C) match the original specification. Supply current per channel is 4.4 mA, substantially higher than the LMV772MAX baseline. All three variants are active and RoHS3 compliant. Selection among tube (ADA4891-2ARZ), cut-tape (ADA4891-2ARZ-R7), and tape-and-reel (ADA4891-2ARZ-RL) packaging depends on production methodology. These parts are suitable for applications requiring higher bandwidth and faster transient response.

Package-Variant Alternatives (8-SOP Package):

Rohm Semiconductor offers four dual-circuit, rail-to-rail amplifiers in 8-SOP package (0.173", 4.40mm width), which differs from the LMV772MAX 8-SOIC footprint (0.154", 3.90mm width). These alternatives require PCB layout modification but maintain surface-mount compatibility and dual-circuit configuration.

The BU7266F-E2 and BU7266SF-E2 are ultra-low-power CMOS amplifiers with slew rate of 0.0024V/µs and gain bandwidth product of 4 kHz, suitable only for DC and very-low-frequency applications. Supply current is 700 nA, exceptionally low for power-constrained designs. Operating temperature range differs: BU7266F-E2 supports -40°C to 85°C, while BU7266SF-E2 extends to -40°C to 105°C. Both are active and RoHS3 compliant.

The BU7486F-E2 provides moderate performance with slew rate of 10V/µs and gain bandwidth product of 10 MHz. Supply voltage minimum is 3V (versus 2.7V for LMV772MAX), restricting low-voltage applications. Operating temperature range is -40°C to 105°C. This part is active and RoHS3 compliant.

The LMR932F-GE2 (Rohm) is a general-purpose amplifier with slew rate of 0.35V/µs and gain bandwidth product of 1.4 MHz, providing lower performance than the LMV772MAX. Supply voltage range is 1.8V to 5V, and operating temperature is -40°C to 85°C. Supply current is 140 µA per channel, lower than the LMV772MAX. This part is active and RoHS3 compliant.

Compliance Considerations:

The LMV772MAX is RoHS non-compliant. All recommended active substitutes (LMV772MAX/NOPB, ADA4692 series, ADA4891 series, BU7266 series, BU7486F-E2, LMR932F-GE2) are RoHS3 compliant, meeting current environmental and regulatory requirements for new designs and production.

Frequently Asked Questions (FAQ)

Q1: Can I use LMV772MAX/NOPB as a direct replacement for the obsolete LMV772MAX?

A: Yes. The LMV772MAX/NOPB is the active equivalent of the obsolete LMV772MAX. Both parts share identical electrical specifications, pinout, and 8-SOIC package dimensions (0.154", 3.90mm width). No PCB modification is required. The primary difference is product status and RoHS compliance: LMV772MAX/NOPB is active and RoHS3 compliant.

Q2: What are the key differences between the ADA4692-2ARZ and the LMV772MAX?

A: The ADA4692-2ARZ maintains the 8-SOIC package and dual-circuit, rail-to-rail configuration. Electrical differences include: slew rate of 1.3V/µs (versus 1.4V/µs), gain bandwidth product of 3.6 MHz (versus 3.5 MHz), input bias current of 0.5 pA (versus 0.23 pA), input offset voltage of 500 µV (versus 250 µV), and supply current of 180 µA per channel (versus 600 µA). The ADA4692-2ARZ is active and RoHS3 compliant. Supply voltage range is 2.7V to 5V (versus 5.5V maximum for LMV772MAX).

Q3: When should I consider the ADA4891-2ARZ instead of the ADA4692-2ARZ?

A: The ADA4891-2ARZ is a high-performance CMOS amplifier suitable for applications requiring significantly faster response. It provides slew rate of 210V/µs (150× faster than LMV772MAX), gain bandwidth product of 105 MHz (30× higher), and output current of 125 mA (67% higher). However, supply current is 4.4 mA per channel, substantially higher than the LMV772MAX baseline of 600 µA. Select the ADA4891-2ARZ for bandwidth-critical applications; select the ADA4692-2ARZ for power-constrained designs requiring comparable performance to the original part.

Q4: Can I use Rohm Semiconductor parts (BU7266, BU7486, LMR932) as replacements?

A: Rohm parts are available in 8-SOP package (0.173", 4.40mm width), which differs from the LMV772MAX 8-SOIC footprint (0.154", 3.90mm width). PCB layout modification is required. Electrical performance varies significantly: BU7266 series are ultra-low-power DC amplifiers unsuitable for AC applications; BU7486F-E2 provides moderate performance with 10 MHz bandwidth; LMR932F-GE2 offers lower performance than the LMV772MAX. All are active and RoHS3 compliant. Use Rohm alternatives only when package footprint change is acceptable and performance requirements align with the specific device.

Q5: What is the difference between ADA4891-2ARZ, ADA4891-2ARZ-R7, and ADA4891-2ARZ-RL?

A: All three variants share identical electrical specifications and 8-SOIC package. The differences are packaging format: ADA4891-2ARZ is supplied in tube packaging; ADA4891-2ARZ-R7 is cut-tape with digi-reel; ADA4891-2ARZ-RL is tape-and-reel. Selection depends on production volume and automated assembly requirements. Tube packaging is typical for lower volumes; tape-and-reel is standard for high-volume automated pick-and-place assembly.

Q6: Are all substitute parts RoHS compliant?

A: Yes. All recommended active substitutes are RoHS3 compliant. The original LMV772MAX is RoHS non-compliant. For new designs and production requiring RoHS compliance, any of the recommended active substitutes satisfy regulatory requirements.

Q7: What is the operating temperature range for each substitute?

A: LMV772MAX/NOPB, ADA4692-2ARZ series, and ADA4891-2ARZ series support -40°C to 125°C. BU7266F-E2 supports -40°C to 85°C; BU7266SF-E2 supports -40°C to 105°C; BU7486F-E2 supports -40°C to 105°C; LMR932F-GE2 supports -40°C to 85°C. Verify temperature range compatibility with your application requirements before selection.

Q8: Which substitute offers the lowest power consumption?

A: The BU7266 series (BU7266F-E2 and BU7266SF-E2) provide the lowest supply current at 700 nA, suitable only for DC and very-low-frequency applications. For general-purpose amplification, the ADA4692-2ARZ offers significantly lower supply current (180 µA per channel) compared to the LMV772MAX (600 µA per channel), while maintaining comparable performance and the same 8-SOIC package footprint.

Q9: Can I use these substitutes in applications requiring high-frequency performance?

A: The ADA4891-2ARZ series are optimized for high-frequency applications, with gain bandwidth product of 105 MHz and slew rate of 210V/µs. The ADA4692-2ARZ provides moderate bandwidth (3.6 MHz) comparable to the LMV772MAX (3.5 MHz). The BU7266 series and LMR932F-GE2 are unsuitable for high-frequency applications due to very low bandwidth specifications.
