MAX4265ESA+ Equivalent & Substitute Parts

Part Overview

The MAX4265ESA+ is a voltage feedback amplifier manufactured by Analog Devices Inc./Maxim Integrated, designed for linear signal conditioning applications requiring high-speed amplification. This single-circuit operational amplifier operates across a 4.5V to 8V supply range with a 400 MHz gain bandwidth product and 900V/µs slew rate. The device is currently in active production status with 2200 units available in stock. Alternative equivalent parts are identified based on matching electrical performance parameters, mechanical compatibility, and regulatory compliance within the voltage feedback amplifier category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4265ESA+ is determined by strict alignment of the following critical parameters:

Mechanical Compatibility: Package type must be 8-SOIC with identical 0.154" (3.90mm) width to ensure PCB footprint compatibility without layout redesign.

Functional Classification: Amplifier type must be voltage feedback topology with single circuit configuration to maintain circuit behavior and feedback network compatibility.

Electrical Performance Envelope: The substitute must operate within the defined supply voltage range (minimum 4.5V, maximum 8V) and support the operating temperature range of -40°C to 85°C.

Regulatory Compliance: Both RoHS3 compliance and MSL Level 1 rating are required for manufacturing process compatibility and moisture handling procedures.

The THS4275D from Texas Instruments meets all mechanical and regulatory requirements. While this substitute exhibits different electrical characteristics in slew rate, bandwidth, and bias current specifications, these differences remain within acceptable substitution parameters for the voltage feedback amplifier category when supply voltage constraints are observed.

Engineering Selection Recommendations

Primary Selection (MAX4265ESA+): Recommended for applications where the specified 4.5V to 8V supply range and 900V/µs slew rate are design requirements. Active production status with 2200 units in stock ensures supply continuity. ROHS3 compliance and MSL Level 1 rating support standard manufacturing processes.

Substitute Selection (THS4275D): Acceptable as an equivalent when the application supply voltage does not exceed 8V maximum. The THS4275D supports extended supply voltage operation up to 15V, providing design flexibility for future applications. Active production status with 1202 units in stock provides alternative sourcing. ROHS3 compliance and MSL Level 1 rating maintain manufacturing process compatibility.

Both parts maintain identical operating temperature range (-40°C to 85°C) and package footprint (8-SOIC), ensuring mechanical and thermal compatibility in existing designs. Selection between these parts should be based on supply voltage requirements and component availability at the time of procurement.

Frequently Asked Questions (FAQ)

Q: Can the THS4275D directly replace the MAX4265ESA+ in an existing circuit?

A: Direct replacement is possible when the circuit supply voltage remains within 4.5V to 8V. The THS4275D has identical package footprint and pin configuration. However, the higher -3dB bandwidth (1.4 GHz vs. 400 MHz) and different input bias current (6 µA vs. 3.5 µA) may affect circuit performance in precision applications. Circuit validation is required for critical applications.

Q: What are the key differences between these two parts?

A: The primary differences are: THS4275D has higher slew rate (1000V/µs vs. 900V/µs), higher -3dB bandwidth (1.4 GHz vs. 400 MHz), higher input bias current (6 µA vs. 3.5 µA), higher input offset voltage (5 mV vs. 1 mV), lower supply current (22 mA vs. 28 mA), and extended maximum supply voltage (15V vs. 8V).

Q: Are both parts available in the same package?

A: Yes. Both MAX4265ESA+ and THS4275D are packaged in 8-SOIC with 0.154" (3.90mm) width, ensuring identical PCB footprint compatibility without layout modifications.

Q: What is the supply voltage constraint for substitution?

A: The MAX4265ESA+ operates from 4.5V to 8V. The THS4275D operates from 5V to 15V. When substituting with THS4275D, ensure the minimum supply voltage is at least 5V. If your design operates below 5V, the MAX4265ESA+ is the only suitable option.

Q: Are both parts RoHS compliant?

A: Yes. Both MAX4265ESA+ and THS4275D are ROHS3 compliant with MSL Level 1 rating, meeting current environmental and manufacturing standards.

Q: Which part should I select for new designs?

A: Selection depends on supply voltage requirements. For designs operating at 4.5V to 8V, either part is acceptable. For designs requiring extended supply voltage capability or lower supply current, THS4275D is preferred. Verify circuit performance with the specific electrical characteristics of the selected part.
