LMV982MMX Equivalent & Substitute Parts

Part Overview

The LMV982MMX is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in a 10-VSSOP surface mount package. This device delivers rail-to-rail output capability with a 1.5 MHz gain bandwidth product and operates across a 1.8 V to 5 V supply range. The LMV982MMX is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility while meeting current RoHS and environmental compliance standards.

Rail-to-rail output capability
10-pin surface mount package (10-VSSOP, 10-TFSOP, or 10-MSOP compatible)
Supply voltage range: 1.8 V to 5 V minimum overlap

Performance Criteria:

Gain bandwidth product of 1.5 MHz or greater
Slew rate of 0.42 V/µs or greater

Engineering Selection Recommendations

Direct Equivalent (Recommended for Pin-Compatible Replacement):

LMV982MMX/NOPB is the direct equivalent of the obsolete LMV982MMX. This part maintains identical electrical specifications, package configuration, and pinout. The primary distinction is product status: LMV982MMX/NOPB is active and ROHS3 compliant, eliminating obsolescence risk and meeting current environmental regulations. This part is suitable for direct substitution in existing designs without circuit modification.

Functional Equivalents (For New Designs and Performance-Optimized Applications):

MAX9917EUB+ and MAX9917EUB+T are functional equivalents manufactured by Analog Devices Inc./Maxim Integrated. These parts exceed the LMV982MMX in several performance metrics: slew rate of 0.5 V/µs (versus 0.42 V/µs), input bias current of 1 pA (versus 14 nA), and input offset voltage of 200 µV (versus 1 mV). Both are ROHS3 compliant and active products. The MAX9917EUB+T variant in tape and reel packaging is recommended for high-volume production. However, output current per channel is limited to 15 mA, compared to 100 mA for the LMV982MMX, restricting use in high-current output applications.

MAX9913EUB+ and MAX9913EUB+T are functional equivalents with lower performance specifications. Gain bandwidth product is 200 kHz (versus 1.5 MHz), and slew rate is 0.1 V/µs (versus 0.42 V/µs). These parts are suitable only for low-frequency applications where bandwidth and slew rate requirements are significantly reduced. Supply current is substantially lower at 7 µA per channel, making these parts advantageous for battery-powered or ultra-low-power applications.

Compliance Considerations:

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The LMV982MMX/NOPB is the preferred choice for compliance-critical applications requiring direct equivalence.

Frequently Asked Questions (FAQ)

Q: Can the MAX9913EUB+ or MAX9913EUB+T be used as a direct replacement for the LMV982MMX?

A: No. While both parts are dual-channel, rail-to-rail general-purpose amplifiers in compatible packages, the MAX9913 series has significantly lower gain bandwidth product (200 kHz versus 1.5 MHz) and slew rate (0.1 V/µs versus 0.42 V/µs). These parts are suitable only for applications where bandwidth and slew rate requirements are substantially lower than the original design specification.

Q: What is the difference between LMV982MMX and LMV982MMX/NOPB?

A: Both parts are electrically and functionally identical with the same pinout and package. The primary differences are product status and compliance: LMV982MMX is obsolete and RoHS non-compliant, while LMV982MMX/NOPB is active and ROHS3 compliant. The "/NOPB" designation indicates lead-free, halogen-free packaging. LMV982MMX/NOPB is the recommended choice for new designs and ongoing production.

Q: Can the MAX9917EUB+ replace the LMV982MMX in all applications?

A: The MAX9917EUB+ meets or exceeds most electrical specifications of the LMV982MMX, including slew rate, input bias current, and input offset voltage. However, output current per channel is limited to 15 mA compared to 100 mA for the LMV982MMX. Applications requiring high output current (greater than 15 mA per channel) cannot use the MAX9917 series without external buffering or alternative circuit topology.

Q: What packaging options are available for substitute parts?

A: LMV982MMX/NOPB is available in Tape & Reel (TR) packaging. MAX9913EUB+ is supplied in Tube packaging, while MAX9913EUB+T is available in Tape & Reel (TR). MAX9917EUB+ is supplied in Tube packaging, and MAX9917EUB+T is available in Cut Tape (CT) & Digi-Reel® packaging. Selection depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. LMV982MMX/NOPB, MAX9913EUB+, MAX9913EUB+T, MAX9917EUB+, and MAX9917EUB+T are all ROHS3 compliant. The original LMV982MMX is RoHS non-compliant and should not be used in new designs subject to RoHS regulations.

Q: What is the operating temperature range difference between the LMV982MMX and substitute parts?

A: The LMV982MMX operates from -40°C to 125°C. All substitute parts (LMV982MMX/NOPB, MAX9913 series, and MAX9917 series) operate from -40°C to 85°C. Applications requiring operation above 85°C cannot use these substitute parts.

Q: Which substitute part is recommended for battery-powered applications?

A: The MAX9913EUB+ or MAX9913EUB+T is recommended for ultra-low-power applications. Supply current is 7 µA per channel (versus 116 µA for the LMV982MMX), significantly extending battery life. However, this selection is appropriate only for applications where the lower gain bandwidth product (200 kHz) and slew rate (0.1 V/µs) meet design requirements.
