MAX4275AGEUA Equivalent & Substitute Parts Reference

Part Overview

The MAX4275AGEUA is a general purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, featuring dual circuits in an 8-uMAX-EP package with rail-to-rail output capability. This device is classified as obsolete, which necessitates identification of active equivalent and substitute components for new designs and production continuity.

The MAX4275AGEUA operates across a 2.5V to 5.5V supply range and is suitable for low-power applications requiring dual-channel amplification. Due to its obsolete status, equivalent active alternatives must be evaluated based on electrical performance parameters and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the MAX4275AGEUA is determined by the following critical parameters:

Primary Substitution Criteria:

Dual-channel configuration (2 circuits)
Rail-to-rail output capability
Surface mount 8-pin package (TSSOP/MSOP family)
Supply voltage range compatibility (minimum 2.5V, maximum 5.5V)
Operating temperature range (-40°C to 85°C minimum)

Secondary Performance Considerations:

Slew rate (0.7V/µs baseline)
Gain bandwidth product (2 MHz baseline)
Input bias current (50 pA baseline)
Input offset voltage (500 µV baseline)
Supply current and output current capabilities

Substitute parts are grouped into two categories based on amplifier type: General Purpose amplifiers and CMOS amplifiers. General Purpose substitutes maintain similar performance profiles to the original device. CMOS substitutes offer lower input bias current and reduced supply current, making them suitable for low-power applications.

Engineering Selection Recommendations

Compliance and Regulatory Status:

All substitute parts listed are active products with ROHS3 compliance, addressing the RoHS non-compliance status of the obsolete MAX4275AGEUA. This compliance upgrade is mandatory for new designs subject to RoHS regulations.

Product Status Advantage:

The substitute parts are all classified as active products with ongoing manufacturer support, ensuring long-term availability and supply chain continuity compared to the obsolete MAX4275AGEUA.

Moisture Sensitivity Consideration:

The AZV832MMTR-G1 carries MSL 3 (168 Hours), requiring controlled storage and handling. All other substitutes maintain MSL 1 (Unlimited), matching or exceeding the original device's moisture tolerance.

Temperature Range Extensions:

The LMV552MM/NOPB, LMV552MMX/NOPB, and LMV772MM/NOPB extend the operating temperature range to -40°C to 125°C, providing enhanced thermal performance for applications requiring extended temperature operation beyond the original -40°C to 85°C specification.

LME49726MYX/NOPB is classified as an audio amplifier with enhanced performance characteristics including 3.7V/µs slew rate and 6.25 MHz gain bandwidth product. This device is suitable for audio-specific applications requiring higher bandwidth and slew rate performance.

Frequently Asked Questions (FAQ)

Q: Can the AZV832MMTR-G1 directly replace the MAX4275AGEUA in all applications?

A: The AZV832MMTR-G1 is electrically compatible as a dual-channel, rail-to-rail CMOS amplifier in the same 8-MSOP package. However, it carries MSL 3 moisture sensitivity versus MSL 1 for the original device, requiring controlled storage conditions. The lower input bias current (1 pA vs. 50 pA) and reduced supply current (70 µA vs. 355 µA) make it suitable for low-power applications but may require circuit verification for applications sensitive to input bias current characteristics.

Q: What is the difference between the BU7442 and BU7462 series?

A: Both are dual-channel, rail-to-rail amplifiers in 8-MSOP packages from Rohm Semiconductor. The BU7442 series is classified as general purpose with 0.3V/µs slew rate and 600 kHz gain bandwidth product. The BU7462 series is CMOS-based with 1V/µs slew rate and 1 MHz gain bandwidth product, offering higher speed performance and lower input bias current (1 pA). The BU7442SFVM-TR and BU7462SFVM-TR variants extend operating temperature to -40°C to 105°C.

Q: Are package dimensions compatible between all substitute parts?

A: Package compatibility varies. The MAX4275AGEUA uses 8-TSSOP/8-MSOP with 0.118" (3.00mm) width and exposed pad. The BU7442 and BU7462 series use 8-VSSOP/8-MSOP with 0.110" (2.80mm) width. The LME49726MYX/NOPB, LMR358FVJ-GE2, LMV552 series, and LMV772MM/NOPB use 8-TSSOP/8-MSOP with 0.118" (3.00mm) width, providing direct footprint compatibility. Verify PCB layout compatibility before substitution.

Q: Which substitute offers the best low-power performance?

A: The LMV552MM/NOPB and LMV552MMX/NOPB offer the lowest supply current at 37 µA (x2 Channels), compared to 355 µA for the original MAX4275AGEUA. These devices are optimized for battery-powered and low-power applications while maintaining 3 MHz gain bandwidth product and rail-to-rail output capability.

Q: Can I use the LMV772MM/NOPB as a substitute?

A: The LMV772MM/NOPB is compatible as a dual-channel, rail-to-rail amplifier in the same 8-TSSOP/8-MSOP package. It offers differential output capability in addition to rail-to-rail output, 1.4V/µs slew rate, and extended temperature range to -40°C to 125°C. The higher supply current (600 µA) and output current (75 mA) make it suitable for applications requiring higher drive capability.

Q: What is the significance of the ROHS3 compliance on all substitutes?

A: ROHS3 compliance indicates adherence to the Restriction of Hazardous Substances Directive, eliminating lead, mercury, cadmium, and other restricted substances. This is mandatory for products sold in the European Union and increasingly required globally. The original MAX4275AGEUA is RoHS non-compliant, making the transition to ROHS3-compliant substitutes necessary for regulatory compliance in new designs.

Q: Which substitute has the highest output current capability?

A: The LME49726MYX/NOPB provides 350 mA output current per channel, significantly exceeding the original MAX4275AGEUA's 65 mA specification. This device is suitable for applications requiring higher output drive capability, such as audio amplification or high-current buffering applications.

Q: Are there supply voltage range differences I should consider?

A: The original MAX4275AGEUA operates from 2.5V to 5.5V. Most substitutes operate from 1.6V to 5.5V (AZV832MMTR-G1) or 1.7V to 5.5V (BU7442, BU7462 series), providing extended low-voltage operation. The LME49726MYX/NOPB, LMR358FVJ-GE2, and LMV series maintain the 2.7V minimum supply voltage. Verify that your application's supply voltage is compatible with the selected substitute.
