LM7372IMA Equivalent & Substitute Parts

Part Overview

The LM7372IMA is a voltage feedback operational amplifier featuring dual circuits in a 16-SOIC surface mount package. Manufactured by Texas Instruments, this device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The LM7372IMA delivers high-speed amplification with a 3000V/µs slew rate and 120 MHz gain bandwidth product, suitable for applications requiring fast signal processing and high output current capability of 260 mA per channel. Identification of equivalent and substitute parts is necessary due to the Last Time Buy status, which restricts future procurement from standard distribution channels.

Substitute Part Grouping Explanation

Substitute parts for the LM7372IMA are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Electrical Parameters (Must Match):

• Amplifier Type: Voltage Feedback
• Number of Circuits: 2
• Slew Rate: 3000 V/µs
• Gain Bandwidth Product: 120 MHz
• -3dB Bandwidth: 220 MHz
• Current - Input Bias: 2.7 µA
• Voltage - Input Offset: 2 mV
• Current - Supply: 13 mA (x2 Channels)
• Current - Output / Channel: 260 mA
• Voltage - Supply Span: 9 V to 36 V
• Operating Temperature: -40°C to 85°C

Mechanical Parameters (Must Match):

• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts differ only in packaging format (Tube vs. Tape & Reel vs. Bulk) and product status (Last Time Buy vs. Active), which do not affect electrical or mechanical compatibility in circuit applications.

Engineering Selection Recommendations

LM7372IMAX/NOPB is the manufacturer-recommended substitute for the LM7372IMA. This part maintains identical electrical and mechanical specifications while offering Active product status, ensuring continued availability through standard distribution channels. The LM7372IMAX/NOPB is supplied in Tape & Reel packaging, which is standard for high-volume production environments and automated assembly processes.

LM7372IMA/NOPB is a parametric equivalent manufactured by National Semiconductor. This part provides identical electrical performance and package compatibility. The LM7372IMA/NOPB is supplied in Bulk packaging format and maintains Active product status. Both substitute parts are ROHS3 compliant and carry identical compliance certifications (ECCN: EAR99; HTSUS: 8542.33.0001).

Selection between substitute parts should be based on packaging requirements and procurement logistics. The LM7372IMAX/NOPB is preferred for automated assembly workflows requiring Tape & Reel format. The LM7372IMA/NOPB is suitable for applications where Bulk packaging is acceptable.

Frequently Asked Questions (FAQ)

Q: Can LM7372IMAX/NOPB be used as a direct replacement for LM7372IMA in existing circuit designs?

A: Yes. The LM7372IMAX/NOPB is electrically and mechanically identical to the LM7372IMA. All electrical parameters, including slew rate, gain bandwidth product, input bias current, output current capability, and supply voltage range are identical. The 16-SOIC package dimensions and pinout are unchanged. The only difference is packaging format (Tape & Reel vs. Tube) and product status (Active vs. Last Time Buy).

Q: What is the difference between LM7372IMA and LM7372IMAX/NOPB?

A: The LM7372IMA and LM7372IMAX/NOPB differ only in packaging format and product status. The LM7372IMA is supplied in Tube packaging and carries Last Time Buy status. The LM7372IMAX/NOPB is supplied in Tape & Reel format and maintains Active status. All electrical specifications, mechanical dimensions, and compliance certifications are identical.

Q: Is the LM7372IMA/NOPB from National Semiconductor compatible with designs using the Texas Instruments LM7372IMA?

A: Yes. The LM7372IMA/NOPB is a parametric equivalent with identical electrical performance and package compatibility. All key parameters including amplifier type, circuit count, slew rate, gain bandwidth product, input bias current, output current, and supply voltage range are identical. The 16-SOIC package and surface mount configuration are unchanged.

Q: What packaging formats are available for LM7372 substitutes?

A: Three packaging formats are available: Tube (LM7372IMA), Tape & Reel (LM7372IMAX/NOPB), and Bulk (LM7372IMA/NOPB). Tape & Reel format is standard for automated assembly and high-volume production. Tube packaging is used for manual assembly and lower-volume applications. Bulk packaging is suitable for applications where individual component handling is acceptable.

Q: Are all LM7372 variants ROHS3 compliant?

A: Yes. All listed variants (LM7372IMA, LM7372IMAX/NOPB, and LM7372IMA/NOPB) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All parts carry identical compliance certifications: ECCN EAR99 and HTSUS 8542.33.0001.

Q: Why is the LM7372IMA marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this specific part number. Existing inventory remains available, but future procurement will not be possible through standard channels. Substitution with active product variants (LM7372IMAX/NOPB or LM7372IMA/NOPB) is recommended for long-term design continuity.
