LMV772MM Equivalent & Substitute Parts

Part Overview

The LMV772MM is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in an 8-VSSOP surface-mount package. This device is classified as Obsolete and has been superseded by the LMV772MM/NOPB variant, which maintains identical electrical specifications while offering Active product status and improved compliance certifications.

The LMV772MM operates across a 2.7 V to 5.5 V supply range with rail-to-rail differential output capability, making it suitable for low-power analog signal conditioning applications. Due to its obsolete status and non-RoHS3 compliance, direct replacement with functionally equivalent or performance-enhanced alternatives is necessary for new designs and ongoing production support.

Engineering Selection Recommendations

For Direct Replacement (Recommended for Existing Designs):

LMV772MM/NOPB is the primary substitute for the obsolete LMV772MM. This part maintains identical electrical specifications and mechanical compatibility while offering Active product status and RoHS3 compliance. Selection of this variant eliminates design changes and ensures long-term supply availability. The /NOPB designation indicates lead-free, halogen-free manufacturing in compliance with current environmental standards.

For Performance-Enhanced Applications:

The ADA4891-2ARMZ family (including R7 and RL packaging variants) provides 30× higher gain-bandwidth product (105 MHz vs. 3.5 MHz) and 150× faster slew rate (210 V/µs vs. 1.4 V/µs). These devices maintain the 2.7 V to 5.5 V supply range and -40°C to 125°C operating temperature compatibility. Selection is appropriate when signal bandwidth requirements exceed the LMV772MM capability. All three variants (ARMZ, ARMZ-R7, ARMZ-RL) are electrically identical; packaging format selection depends on procurement and assembly requirements (Tube, Cut Tape & Digi-Reel, or Tape & Reel).

For Ultra-Low-Power Applications:

BU7266FVM-TR and BU7266SFVM-TR reduce supply current to 700 nA (1000× lower than LMV772MM) and extend the minimum supply voltage to 1.8 V. These devices are suitable for battery-powered systems where power consumption is critical. BU7266SFVM-TR extends the operating temperature range to 105°C compared to BU7266FVM-TR's 85°C maximum. Trade-offs include significantly reduced bandwidth (4 kHz) and slew rate (0.0024 V/µs), limiting application to DC and very-low-frequency signal conditioning.

For Moderate-Performance Requirements:

BU7486FVM-TR offers intermediate performance (10 MHz bandwidth, 10 V/µs slew rate) with 6 mA supply current and 12 mA output current per channel. Operating temperature range extends to 105°C. Minimum supply voltage is 3 V, restricting use in lower-voltage systems. LMV358M8G-13 provides 1 MHz bandwidth with reduced supply current (190 µA) and maintains full -40°C to 125°C temperature range, suitable for general-purpose applications with moderate speed requirements.

For Precision Low-Offset Applications:

MAX4252EUA+ features the lowest input offset voltage (70 µV vs. 250 µV) and lowest input bias current (0.1 pA vs. 0.23 pA), with reduced supply current (420 µA). Operating temperature range is limited to -40°C to 85°C. MAX4486AUA+T provides higher slew rate (20 V/µs) and bandwidth (7 MHz) with extended temperature range (-40°C to 125°C) and maintains low input bias current (0.1 pA).

Compliance and Supply Considerations:

All recommended substitutes are RoHS3 compliant and carry Active product status, ensuring long-term availability and regulatory compliance. Inventory levels vary; ADA4891-2ARMZ-R7 (3983 pcs), ADA4891-2ARMZ-RL (3446 pcs), and MAX4486AUA+T (845 pcs) show lower stock levels compared to LMV772MM/NOPB (21577 pcs) and MAX4252EUA+ (100300 pcs). Procurement planning should account for these availability differences.

Frequently Asked Questions (FAQ)

Q1: Can LMV772MM/NOPB be used as a direct drop-in replacement for LMV772MM?

A: Yes. LMV772MM/NOPB is electrically and mechanically identical to LMV772MM, with identical pin configuration, package dimensions (8-VSSOP), and all electrical specifications. The primary differences are product status (Active vs. Obsolete) and compliance certifications (RoHS3 compliant vs. non-compliant). No circuit modifications are required.

Q2: What are the key differences between the ADA4891-2ARMZ variants (ARMZ, ARMZ-R7, ARMZ-RL)?

A: All three variants (ADA4891-2ARMZ, ADA4891-2ARMZ-R7, ADA4891-2ARMZ-RL) are electrically identical with identical specifications. Differences are packaging and delivery format only: ARMZ is supplied in Tube packaging, ARMZ-R7 in Cut Tape & Digi-Reel format, and ARMZ-RL in Tape & Reel format. Selection depends on assembly process requirements and procurement preferences.

Q3: Why does BU7266FVM-TR have such low bandwidth (4 kHz) compared to LMV772MM (3.5 MHz)?

A: BU7266FVM-TR is optimized for ultra-low-power operation (700 nA supply current vs. 600 µA), achieving this through reduced gain-bandwidth product. This device is intended for DC and very-low-frequency applications such as sensor signal conditioning in battery-powered systems. Applications requiring higher bandwidth must select alternatives such as LMV772MM/NOPB, BU7486FVM-TR, or ADA4891-2ARMZ.

Q4: Can MAX4252EUA+ or MAX4486AUA+T be used in applications requiring -40°C to 125°C operation?

A: MAX4252EUA+ is limited to -40°C to 85°C operation and is not suitable for applications requiring the full -40°C to 125°C range. MAX4486AUA+T supports the full -40°C to 125°C range and is appropriate for extended-temperature applications. Verify application temperature requirements before selection.

Q5: Are all substitute parts available in 8-pin surface-mount packages compatible with LMV772MM PCB layouts?

A: Package compatibility requires verification. LMV772MM uses 8-VSSOP (0.118" width, 3.00 mm). Most substitutes use 8-MSOP or 8-uMAX packages with identical 0.118" width and 3.00 mm body dimensions, ensuring PCB footprint compatibility. However, MAX4252EUA+ and MAX4486AUA+T use 8-uMAX/uSOP packaging. Confirm footprint dimensions in component datasheets before PCB layout finalization. Pin assignments are identical across all recommended substitutes.

Q6: What is the significance of the /NOPB designation in LMV772MM/NOPB?

A: /NOPB indicates "No Plumbum" (lead-free) manufacturing. This designation confirms compliance with RoHS (Restriction of Hazardous Substances) directives prohibiting lead in electronic components. All modern substitutes carry this designation or equivalent RoHS3 compliance marking.

Q7: Which substitute offers the best balance of performance and power consumption for general-purpose applications?

A: LMV772MM/NOPB maintains the original performance-to-power ratio (3.5 MHz bandwidth, 600 µA supply current). For improved performance with acceptable power increase, MAX4486AUA+T provides 7 MHz bandwidth and 20 V/µs slew rate with 2.2 mA supply current. For lowest power consumption in general-purpose applications, LMV358M8G-13 offers 1 MHz bandwidth with only 190 µA supply current. Selection depends on specific bandwidth and power budget requirements.
