MAX4265ESA-T Equivalent & Substitute Parts

Part Overview

The MAX4265ESA-T is a voltage feedback amplifier integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This single-circuit operational amplifier is housed in an 8-SOIC surface mount package and delivers a gain bandwidth product of 400 MHz with a slew rate of 900V/µs. The device operates across a supply voltage range of 4.5V to 8V and is rated for temperatures from -40°C to 85°C.

The MAX4265ESA-T carries an Obsolete product status. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design flexibility is required for new production runs. Direct equivalents and manufacturer-recommended alternatives are available to maintain circuit functionality and performance specifications.

Substitute Part Grouping Explanation

Substitution of the MAX4265ESA-T is determined by strict adherence to the following criteria:

Primary Substitution Criteria:

• Amplifier Type: Voltage Feedback
• Number of Circuits: 1
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 85°C minimum
• RoHS Compliance: ROHS3 Compliant

Electrical Parameter Compatibility: Substitute parts must maintain compatibility within the following parameter ranges:

• Slew Rate: 900V/µs or greater
• Gain Bandwidth Product: 400 MHz or greater
• -3dB Bandwidth: 400 MHz or greater
• Current - Input Bias: 3.5 µA or lower
• Voltage - Input Offset: 1 mV or lower
• Current - Supply: 28 mA or lower
• Current - Output / Channel: 45 mA or greater
• Voltage - Supply Span: Must encompass 4.5V to 8V range

Substitute parts are grouped into two categories: Direct Equivalents (identical specifications and product lineage) and Manufacturer-Recommended Alternatives (functionally compatible with enhanced or equivalent performance characteristics).

Engineering Selection Recommendations

MAX4265ESA+T (Direct Equivalent)

The MAX4265ESA+T is the direct equivalent substitute for the obsolete MAX4265ESA-T. This part maintains identical electrical specifications across all measured parameters and is housed in the same 8-SOIC package. The MAX4265ESA+T carries Active product status, ensuring continued availability and manufacturer support. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share the same base product number (MAX4265). RoHS3 compliance and MSL rating are identical. This substitute is suitable for direct replacement in existing designs without circuit modification.

THS4275D (Manufacturer-Recommended Alternative)

The THS4275D, manufactured by Texas Instruments, is the manufacturer-recommended alternative for the MAX4265ESA-T. This device maintains the same 8-SOIC package footprint and core voltage feedback amplifier architecture. The THS4275D exhibits enhanced performance characteristics: slew rate of 1000V/µs (versus 900V/µs), -3dB bandwidth of 1.4 GHz (versus 400 MHz), and output current capability of 160 mA per channel (versus 45 mA). Supply current consumption is reduced to 22 mA. The supply voltage range extends to 15V maximum, providing greater flexibility in power supply design. The THS4275D carries Active product status and is ROHS3 compliant with MSL rating of 1. Input bias current is 6 µA and input offset voltage is 5 mV, both within acceptable tolerance for most applications. This substitute is suitable for designs requiring enhanced bandwidth and output drive capability.

Frequently Asked Questions (FAQ)

Q: Can MAX4265ESA+T be used as a direct replacement for MAX4265ESA-T?

A: Yes. The MAX4265ESA+T is a direct equivalent with identical electrical specifications, package, and mounting type. The primary difference is product status: MAX4265ESA+T is Active while MAX4265ESA-T is Obsolete. No circuit modifications are required.

Q: What are the key differences between MAX4265ESA-T and THS4275D?

A: Both devices are single-circuit voltage feedback amplifiers in 8-SOIC packages with identical gain bandwidth product (400 MHz) and operating temperature range (-40°C to 85°C). The THS4275D offers enhanced -3dB bandwidth (1.4 GHz versus 400 MHz), higher slew rate (1000V/µs versus 900V/µs), greater output current capability (160 mA versus 45 mA), and extended supply voltage range (5V to 15V versus 4.5V to 8V). Input offset voltage and input bias current are slightly higher in the THS4275D.

Q: Is the THS4275D pin-compatible with MAX4265ESA-T?

A: Both devices use the 8-SOIC package with identical physical dimensions (0.154" width, 3.90mm). Pin compatibility depends on circuit design and application requirements. Verify pinout assignments in the respective device datasheets before substitution.

Q: Can THS4275D be used in applications designed for MAX4265ESA-T?

A: The THS4275D is suitable for most applications designed for MAX4265ESA-T due to compatible package, operating temperature range, and core amplifier specifications. However, the enhanced bandwidth and output current characteristics may require circuit validation. Applications with strict input offset voltage or input bias current requirements should confirm compatibility with the THS4275D specifications (5 mV offset, 6 µA bias current versus 1 mV offset, 3.5 µA bias current).

Q: What is the inventory status of these substitute parts?

A: MAX4265ESA-T: 992 Pcs New Original In Stock. MAX4265ESA+T: 729 Pcs New Original In Stock. THS4275D: 1202 Pcs New Original In Stock.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MAX4265ESA-T, MAX4265ESA+T, and THS4275D are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the minimum supply voltage for each device?

A: MAX4265ESA-T and MAX4265ESA+T require minimum 4.5V supply. THS4275D requires minimum 5V supply. Verify your power supply design meets the THS4275D requirement if substituting.
