LM7372IMAX Equivalent & Substitute Parts

Part Overview

The LM7372IMAX 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 obsolete, indicating it has been discontinued from active production. The LM7372IMAX delivers high-speed amplification with a gain bandwidth product of 120 MHz and slew rate of 3000 V/µs, suitable for applications requiring precision voltage feedback amplification across a wide supply voltage range of 9 V to 36 V.

Due to its obsolete status, locating equivalent substitute parts with identical electrical and mechanical specifications is essential for design continuity, system maintenance, and component procurement. Substitute parts must maintain compatibility across all critical parameters including amplifier type, circuit count, frequency response, and package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM7372IMAX is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Amplifier type (voltage feedback), number of circuits (2), slew rate (3000 V/µs), gain bandwidth product (120 MHz), -3dB bandwidth (220 MHz), input bias current (2.7 µA), input offset voltage (2 mV), supply current (13 mA per channel), output current per channel (260 mA), and supply voltage range (9 V to 36 V minimum, 36 V maximum).

Mechanical Specifications: Package type (16-SOIC), package dimensions (0.154" width, 3.90 mm width), and mounting type (surface mount).

Compliance & Status: While product status differs between the main part (obsolete) and substitute parts (active), electrical and mechanical parameters remain identical. Compliance certifications including RoHS status and REACH classification are documented separately for each part number variant.

Parameter Comparison

Engineering Selection Recommendations

The LM7372IMAX/NOPB serves as the direct substitute for the obsolete LM7372IMAX. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction between these part numbers is product status and compliance certification.

The LM7372IMAX/NOPB is classified as active, ensuring ongoing availability and supply chain continuity. This part number incorporates ROHS3 compliance, meeting current environmental and regulatory requirements for electronic components. The packaging format differs, with LM7372IMAX/NOPB supplied in Tape & Reel (TR) configuration, which is standard for active production components.

For new designs or component replacement requiring current compliance certifications, the LM7372IMAX/NOPB is the appropriate selection. Both parts are functionally interchangeable at the circuit level, with identical pinout, electrical performance, and thermal characteristics across the specified operating temperature range of -40°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can LM7372IMAX/NOPB be used as a direct replacement for LM7372IMAX?

A: Yes. Both parts are electrically and mechanically identical. All electrical specifications including slew rate, gain bandwidth product, input bias current, output current, and supply voltage range are equivalent. The 16-SOIC package dimensions and pinout are identical, enabling direct substitution in existing PCB layouts.

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

A: The primary differences are product status and compliance certification. LM7372IMAX is obsolete and RoHS non-compliant. LM7372IMAX/NOPB is active production and ROHS3 compliant. Packaging format also differs: LM7372IMAX is supplied in bulk, while LM7372IMAX/NOPB is supplied in Tape & Reel (TR) format. Electrical and mechanical specifications are identical.

Q: Are there any pin compatibility concerns when substituting these parts?

A: No. Both parts use the 16-SOIC package with identical pinout and pin assignments. PCB footprints, solder pad layouts, and component placement are fully compatible.

Q: What is the significance of the /NOPB designation?

A: The /NOPB suffix indicates the part is supplied without plumbum (lead-free), meeting ROHS3 compliance requirements. This designation reflects current manufacturing standards for active production components.

Q: Can the LM7372IMAX be used in applications requiring RoHS compliance?

A: No. The LM7372IMAX is RoHS non-compliant. For applications requiring RoHS compliance, the LM7372IMAX/NOPB must be used.

Q: What supply voltage range is supported by both parts?

A: Both the LM7372IMAX and LM7372IMAX/NOPB support a supply voltage range of 9 V minimum to 36 V maximum, enabling operation across a wide range of power supply configurations.

Q: Is the operating temperature range identical for both parts?

A: Yes. Both parts operate across the temperature range of -40°C to 85°C, maintaining specified electrical performance throughout this range.
