Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4267ESA is determined by strict alignment of electrical and mechanical parameters within the voltage feedback amplifier category. The primary substitution criteria are:

Mechanical Compatibility:

• Identical package type: 8-SOIC (0.154", 3.90mm Width)
• Identical mounting type: Surface Mount
• Identical circuit count: 1 circuit

Electrical Compatibility Parameters:

• Amplifier topology: Voltage Feedback
• Operating temperature range: -40°C to 85°C (matching or exceeding)
• Supply voltage span: Minimum 4.5V to maximum 8V operation capability
• Input bias current, input offset voltage, slew rate, and bandwidth characteristics within acceptable operational ranges for the application

The THS4275D from Texas Instruments meets these substitution criteria through identical package configuration and compatible electrical operating parameters within the specified temperature and supply voltage ranges.

Engineering Selection Recommendations

Product Status Consideration: The MAX4267ESA is classified as obsolete, with no ongoing manufacturing. The THS4275D is an active product from Texas Instruments, ensuring long-term availability and continued manufacturing support.

Compliance and Certification: The THS4275D holds ROHS3 compliance status, whereas the MAX4267ESA is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the THS4275D provides regulatory alignment. Both devices maintain identical Moisture Sensitivity Level (MSL) classification of 1 (Unlimited) and REACH Unaffected status.

Electrical Performance Differences: The THS4275D demonstrates enhanced output current capability (160 mA versus 45 mA per channel) and extended maximum supply voltage range (15V versus 8V maximum). The THS4275D also provides higher slew rate (1000 V/µs versus 900 V/µs). These characteristics represent performance improvements suitable for applications requiring higher output drive capability or extended supply voltage operation.

Package and Mechanical Compatibility: Both devices utilize identical 8-SOIC surface mount packaging (0.154", 3.90mm width), enabling direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the THS4275D be used as a direct replacement for the MAX4267ESA in existing designs?

A: The THS4275D is mechanically compatible through identical 8-SOIC packaging and electrically compatible through matching voltage feedback amplifier topology and operating temperature range. However, electrical parameter differences exist. The THS4275D exhibits higher input offset voltage (5 mV versus 1 mV), higher input bias current (6 µA versus 3.5 µA), and different bandwidth characteristics. Circuit performance validation is required to confirm suitability for specific application requirements.

Q: What are the key electrical differences between these devices?

A: The THS4275D provides higher output current per channel (160 mA versus 45 mA), higher slew rate (1000 V/µs versus 900 V/µs), and extended maximum supply voltage (15V versus 8V). The MAX4267ESA offers lower input offset voltage (1 mV versus 5 mV) and lower input bias current (3.5 µA versus 6 µA). Gain bandwidth product differs significantly (1.5 GHz versus 400 MHz for MAX4267ESA and THS4275D respectively).

Q: Are there packaging considerations for substitution?

A: Both devices are supplied in 8-SOIC surface mount packages with identical physical dimensions (0.154", 3.90mm width). No PCB layout modifications are required for package compatibility. The THS4275D is supplied in tube packaging, whereas the MAX4267ESA packaging format is not specified in available data.

Q: What is the impact of RoHS compliance differences?

A: The MAX4267ESA is RoHS non-compliant, while the THS4275D is ROHS3 compliant. For applications or markets requiring RoHS compliance, the THS4275D satisfies regulatory requirements. Both devices maintain identical REACH Unaffected status.

Q: How do supply voltage ranges compare?

A: The MAX4267ESA operates within 4.5V to 8V supply span. The THS4275D operates within 5V to 15V supply span. Applications requiring operation below 5V supply voltage cannot use the THS4275D. Applications requiring supply voltages above 8V require the THS4275D.
