MAX4282EUA Equivalent & Substitute Parts

Part Overview

The MAX4282EUA is a general purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, featuring dual circuits in a rail-to-rail configuration. This device is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. The MAX4282EUA operates across a 2.5V to 5.5V supply range with a 2 MHz gain bandwidth product and 0.7V/µs slew rate, making it suitable for low-power analog signal processing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4282EUA is determined by the following critical parameters: dual-circuit configuration, rail-to-rail output capability, 8-pin MSOP/TSSOP package compatibility, supply voltage range of 2.5V to 5.5V, and surface mount technology. The substitute parts identified maintain these core electrical and mechanical specifications while offering improvements in product status, RoHS compliance, and extended operating temperature ranges.

The three qualified substitute parts are grouped as follows:

LTC6084HMS8#TRPBF (Analog Devices Inc.): CMOS amplifier with active product status, RoHS3 compliance, and extended temperature range (-40°C to 125°C). Maintains identical supply voltage span and package footprint. Lower slew rate (0.5V/µs) and reduced output current per channel (12.5 mA) compared to the main part.

MCP6472-E/MS (Microchip Technology): CMOS amplifier with active product status, RoHS3 compliance, and extended temperature range (-40°C to 125°C). Maintains identical gain bandwidth product (2 MHz) and package footprint. Higher slew rate (1.1V/µs) and lower minimum supply voltage (2V) than the main part.

MCP6482-E/MS (Microchip Technology): General purpose amplifier with active product status, RoHS3 compliance, and extended temperature range (-40°C to 125°C). Offers higher gain bandwidth product (4 MHz) and slew rate (2.7V/µs) than the main part. Maintains identical package footprint and supply voltage span.

Parameter Comparison

Engineering Selection Recommendations

LTC6084HMS8#TRPBF is recommended for applications requiring RoHS3 compliance, extended operating temperature range, and minimal power consumption. This substitute is suitable for designs where slew rate below 0.7V/µs is acceptable and output current requirements do not exceed 12.5 mA per channel. The lower input bias current (1 pA) provides improved precision in high-impedance signal conditioning circuits.

MCP6472-E/MS is recommended for applications requiring RoHS3 compliance, extended operating temperature range, and identical gain bandwidth product to the original part. This substitute accommodates lower minimum supply voltages (2V) and provides higher slew rate (1.1V/µs) for faster signal transitions. Output current capability of 32 mA per channel supports moderate load driving requirements.

MCP6482-E/MS is recommended for applications requiring RoHS3 compliance, extended operating temperature range, and enhanced bandwidth performance. This substitute provides the highest slew rate (2.7V/µs) and gain bandwidth product (4 MHz) among the three options, enabling use in higher-frequency signal processing applications. Product status is active with full manufacturing support.

All three substitute parts maintain identical package footprints (8-TSSOP, 8-MSOP) and supply voltage range compatibility (2.5V to 5.5V maximum), ensuring direct PCB layout compatibility with the MAX4282EUA.

Frequently Asked Questions (FAQ)

Q: Can the LTC6084HMS8#TRPBF directly replace the MAX4282EUA in all applications?

A: Direct replacement is possible from a package and pinout perspective. However, the LTC6084HMS8#TRPBF has a lower slew rate (0.5V/µs versus 0.7V/µs) and reduced output current per channel (12.5 mA versus 65 mA). Applications requiring high-speed signal transitions or driving loads exceeding 12.5 mA per channel must be evaluated for compatibility.

Q: What are the key differences between MCP6472-E/MS and MCP6482-E/MS?

A: Both parts are manufactured by Microchip Technology and share identical package and supply voltage specifications. The MCP6482-E/MS offers superior performance with a gain bandwidth product of 4 MHz (versus 2 MHz) and slew rate of 2.7V/µs (versus 1.1V/µs). The MCP6472-E/MS provides lower supply current (100 µA versus 240 µA) and higher output current per channel (32 mA versus 12 mA).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts (LTC6084HMS8#TRPBF, MCP6472-E/MS, and MCP6482-E/MS) carry RoHS3 compliance certification, whereas the original MAX4282EUA is RoHS non-compliant. This compliance status is mandatory for applications subject to RoHS regulations.

Q: What is the operating temperature advantage of the substitute parts?

A: The MAX4282EUA operates from -40°C to 85°C. All three substitute parts extend the upper temperature limit to 125°C, providing a 40°C margin for high-temperature environments and thermal stress conditions.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitute parts use identical 8-pin MSOP/TSSOP package footprints with the same pinout as the MAX4282EUA. PCB layout modifications are not required for mechanical or electrical connectivity.

Q: Which substitute part is best for low-power applications?

A: The LTC6084HMS8#TRPBF consumes the lowest supply current at 110 µA (x2 channels), making it the optimal choice for battery-powered or energy-constrained applications.

Q: Which substitute part offers the highest performance?

A: The MCP6482-E/MS provides the highest gain bandwidth product (4 MHz) and slew rate (2.7V/µs), making it suitable for applications requiring faster signal processing and higher-frequency operation.
