Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4481AXT-T is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Package / Case: 6-TSSOP, SC-88, SOT-363
• Mounting Type: Surface Mount
• Supplier Device Package: SC-70-6

Functional Equivalence:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Operating Temperature Range: -40°C to 125°C
• Supply Voltage Range: Minimum 2.5V, Maximum 5.5V

Electrical Performance Envelope: Substitute parts must operate within the specified supply voltage range and temperature range. The MAX4481AXT-T establishes baseline performance metrics; substitute parts with enhanced specifications (higher slew rate, greater gain bandwidth product, lower input offset voltage, or higher output current) are electrically compatible and functionally superior within the same package footprint.

The substitute parts identified below meet all mechanical and functional requirements while maintaining pin-compatible SC-70-6 packaging.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Manufacturer): MAX4481AXT+T is the active production equivalent of MAX4481AXT-T from Analog Devices Inc./Maxim Integrated. This part maintains identical electrical specifications and packaging while achieving ROHS3 compliance status, addressing the RoHS non-compliance limitation of the obsolete MAX4481AXT-T. Selection of MAX4481AXT+T is appropriate for designs requiring continuity with the original MAX4481 architecture and Maxim Integrated supply chain qualification.

Cross-Manufacturer Alternatives (Texas Instruments): LMV341MG/NOPB, LMV341MGX/NOPB, LMV601MG/NOPB, and LMV601MGX/NOPB are functionally equivalent general-purpose operational amplifiers from Texas Instruments. All four parts are ROHS3 compliant and active in production. These devices are pin-compatible within the SC-70-6 package and operate across the required -40°C to 125°C temperature range with 2.7V to 5.5V supply capability.

The Texas Instruments alternatives exhibit enhanced electrical performance characteristics: slew rate of 1V/µs (versus 0.08V/µs), gain bandwidth product of 1 MHz (versus 140 kHz), lower input offset voltage of 250 µV (versus 1 mV), and higher output current capability of 113 mA per channel (versus 17 mA). These performance improvements are backward compatible with applications designed for the MAX4481AXT-T.

Packaging and Supply Considerations: LMV341MG/NOPB and LMV341MGX/NOPB are supplied in Tape & Reel (TR) format with inventory of 35,300 and 2,350 units respectively. LMV601MG/NOPB is available in Cut Tape (CT) & Digi-Reel® format with 4,380 units in stock. LMV601MGX/NOPB is supplied in Tape & Reel (TR) format with 65,400 units available. Selection among these alternatives should consider packaging requirements and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can MAX4481AXT+T be used as a direct replacement for MAX4481AXT-T?

A: Yes. MAX4481AXT+T is the active production equivalent manufactured by Analog Devices Inc./Maxim Integrated. Both parts share identical electrical specifications, package footprint (SC-70-6), and functional characteristics. The primary difference is product status (Active versus Obsolete) and RoHS compliance (ROHS3 Compliant versus RoHS non-compliant). MAX4481AXT+T is supplied in Tape & Reel format with 1,630 units in current inventory.

Q: Are Texas Instruments LMV341 and LMV601 series parts pin-compatible with MAX4481AXT-T?

A: Yes. All substitute parts—LMV341MG/NOPB, LMV341MGX/NOPB, LMV601MG/NOPB, and LMV601MGX/NOPB—are housed in the same 6-TSSOP, SC-88, SOT-363 package configuration with SC-70-6 supplier device package designation. Pin compatibility is confirmed for surface mount assembly.

Q: What are the key electrical differences between MAX4481AXT-T and the Texas Instruments alternatives?

A: The Texas Instruments LMV341 and LMV601 series provide enhanced performance specifications while maintaining functional equivalence. Slew rate increases from 0.08V/µs to 1V/µs, gain bandwidth product increases from 140 kHz to 1 MHz, input offset voltage decreases from 1 mV to 250 µV, and output current per channel increases from 17 mA to 113 mA. Supply current increases from 50 µA to 107 µA. All parts operate across the -40°C to 125°C temperature range and support 2.5V to 5.5V supply operation (Texas Instruments parts specify 2.7V minimum).

Q: Does the minimum supply voltage difference (2.5V for MAX4481 versus 2.7V for LMV341/LMV601) affect substitution?

A: The Texas Instruments parts specify a 2.7V minimum supply voltage compared to 2.5V for the MAX4481AXT-T. In applications operating at supply voltages between 2.5V and 2.7V, the MAX4481AXT+T or MAX4481AXT-T must be retained. For applications operating at 2.7V or higher, Texas Instruments alternatives are fully compatible.

Q: What is the difference between LMV341MG/NOPB and LMV341MGX/NOPB?

A: Both parts are manufactured by Texas Instruments with identical electrical specifications and SC-70-6 packaging. The primary difference is packaging format: LMV341MG/NOPB is supplied in Tape & Reel (TR) with 35,300 units in inventory, while LMV341MGX/NOPB is also supplied in Tape & Reel (TR) with 2,350 units available. Selection should be based on supply chain availability and procurement requirements.

Q: What is the difference between LMV601MG/NOPB and LMV601MGX/NOPB?

A: Both parts are manufactured by Texas Instruments with identical electrical specifications and SC-70-6 packaging. LMV601MG/NOPB is supplied in Cut Tape (CT) & Digi-Reel® format with 4,380 units in stock. LMV601MGX/NOPB is supplied in Tape & Reel (TR) format with 65,400 units available. Selection depends on packaging format preference and supply volume requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. MAX4481AXT+T, LMV341MG/NOPB, LMV341MGX/NOPB, LMV601MG/NOPB, and LMV601MGX/NOPB are all ROHS3 compliant. The original MAX4481AXT-T is RoHS non-compliant. For applications requiring RoHS compliance, any of the substitute parts listed above are suitable alternatives.

Q: Can I use these substitute parts in existing PCB designs without layout modifications?

A: Yes. All substitute parts are housed in the same 6-TSSOP, SC-88, SOT-363 package with SC-70-6 supplier device package designation. PCB footprints, land patterns, and assembly processes remain unchanged. No layout modifications are required for component substitution.
