MAX4482AKA-T Equivalent & Substitute Parts

Part Overview

The MAX4482AKA-T is a general-purpose operational amplifier featuring dual circuits in a surface-mount SOT-23-8 package. This device delivers rail-to-rail output capability with a supply voltage range of 2.5V to 5.5V and operates across the industrial temperature range of -40°C to 125°C. The MAX4482AKA-T is classified as obsolete, necessitating identification of active substitute components for new designs and ongoing production requirements. Equivalent parts must maintain functional compatibility through matching electrical characteristics and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the MAX4482AKA-T are identified based on strict electrical and mechanical parameter matching within the general-purpose dual operational amplifier category. Substitution validity is determined by the following criteria:

Primary Matching Criteria:

• Dual-circuit configuration (2 amplifiers per package)
• Rail-to-rail output capability
• SOT-23-8 surface-mount package
• Operating temperature range: -40°C to 125°C
• Supply voltage compatibility: 2.5V to 5.5V minimum span
• ROHS3 compliance

Secondary Compatibility Parameters:

• Slew rate performance
• Gain bandwidth product
• Input bias current characteristics
• Input offset voltage specifications
• Output current per channel
• Supply current consumption

The substitute parts identified maintain functional equivalence through identical or superior electrical performance within the specified parameter envelope. Packaging and mounting characteristics remain consistent across all qualified substitutes.

Engineering Selection Recommendations

MAX4482AKA+T (Analog Devices Inc./Maxim Integrated)

The MAX4482AKA+T is a direct functional equivalent to the MAX4482AKA-T with identical electrical specifications. This substitute maintains the same slew rate (0.08V/µs), gain bandwidth product (140 kHz), input bias current (0.1 pA), and output current per channel (17 mA). The primary distinction is product status: MAX4482AKA+T is active, whereas MAX4482AKA-T is obsolete. Both devices carry ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The MAX4482AKA+T is supplied in Tape & Reel packaging format, suitable for automated assembly processes.

OPA2379AIDCNT (Texas Instruments)

The OPA2379AIDCNT functions as a cross-manufacturer substitute with compatible package and operating characteristics. This device maintains the dual-circuit, rail-to-rail configuration in SOT-23-8 format with identical operating temperature range (-40°C to 125°C) and maximum supply voltage (5.5V). The OPA2379AIDCNT exhibits lower supply current consumption (2.9µA versus 50µA), reduced input offset voltage (0.4mV versus 1mV), and lower input bias current (5pA versus 0.1pA). However, the OPA2379AIDCNT delivers reduced slew rate (0.03V/µs versus 0.08V/µs) and lower gain bandwidth product (90 kHz versus 140 kHz). The OPA2379AIDCNT carries ROHS3 compliance with MSL 2 rating. Selection of this substitute requires confirmation that reduced slew rate and bandwidth performance are acceptable for the target application.

Frequently Asked Questions (FAQ)

Q: Can MAX4482AKA+T be used as a direct replacement for MAX4482AKA-T?

A: Yes. The MAX4482AKA+T is electrically and mechanically identical to MAX4482AKA-T. Both devices share identical electrical specifications including slew rate, gain bandwidth product, input bias current, and output current ratings. The primary difference is product status: MAX4482AKA+T is active production, while MAX4482AKA-T is obsolete. Both are packaged in SOT-23-8 format for surface-mount assembly.

Q: What are the key differences between MAX4482AKA-T and OPA2379AIDCNT?

A: Both devices are dual general-purpose operational amplifiers in SOT-23-8 packages with rail-to-rail output and identical operating temperature range. The OPA2379AIDCNT offers superior power efficiency with 2.9µA supply current versus 50µA, and lower input offset voltage (0.4mV versus 1mV). However, the OPA2379AIDCNT has reduced slew rate (0.03V/µs versus 0.08V/µs) and lower gain bandwidth product (90 kHz versus 140 kHz). The OPA2379AIDCNT also has lower output current per channel (5mA versus 17mA).

Q: Is the OPA2379AIDCNT suitable for high-speed applications?

A: The OPA2379AIDCNT has lower slew rate (0.03V/µs) and gain bandwidth product (90 kHz) compared to MAX4482AKA-T (0.08V/µs and 140 kHz). Applications requiring higher slew rate or bandwidth performance should retain the MAX4482AKA+T substitute rather than transitioning to OPA2379AIDCNT.

Q: What is the moisture sensitivity difference between these parts?

A: MAX4482AKA-T and MAX4482AKA+T both carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. OPA2379AIDCNT carries MSL 2 (1 Year) rating, requiring storage in controlled humidity conditions and limiting shelf life to one year from manufacturing date.

Q: Are all three parts ROHS3 compliant?

A: Yes. MAX4482AKA-T, MAX4482AKA+T, and OPA2379AIDCNT are all ROHS3 compliant, meeting lead-free and hazardous substance restrictions for European and global markets.

Q: Can OPA2379AIDCNT be used in applications requiring 17mA output current per channel?

A: No. The OPA2379AIDCNT is rated for 5mA output current per channel, compared to 17mA for MAX4482AKA-T. Applications requiring higher output current must use MAX4482AKA+T or equivalent Maxim Integrated devices.

Q: What packaging formats are available for these substitutes?

A: MAX4482AKA-T is supplied in standard packaging format. MAX4482AKA+T is supplied in Tape & Reel (TR) format for automated assembly. OPA2379AIDCNT is supplied in Cut Tape (CT) and Digi-Reel® format. All three maintain identical SOT-23-8 package specifications.
