MAX4311EEE Equivalent & Substitute Parts

Part Overview

The MAX4311EEE is a video amplifier with integrated 4:1 multiplexer-amplifier functionality, manufactured by Analog Devices Inc./Maxim Integrated. This linear amplifier IC operates as a rail-to-rail output device in a 16-QSOP surface mount package. The MAX4311EEE is classified as obsolete product status, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution of the MAX4311EEE is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• -3dB Bandwidth: 345 MHz
• Slew Rate: 430 V/µs
• Current - Supply: 6.9 mA
• Current - Output / Channel: 95 mA
• Voltage - Supply Range: 4V ~ 10.5V (single), ±2V ~ 5.25V (dual)
• Output Type: Rail-to-Rail

Mechanical & Packaging Criteria:

• Package / Case: 16-SSOP (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 16-QSOP

Functional Criteria:

• Application: 4:1 Multiplexer-Amplifier
• Number of Circuits: 1

Substitute parts must match all electrical parameters, package specifications, and functional requirements without deviation. The MAX4311EEE+ is identified as a direct substitute based on complete parameter alignment and identical base product number (MAX4311).

Engineering Selection Recommendations

The MAX4311EEE+ is the direct substitute for the obsolete MAX4311EEE. Selection of the MAX4311EEE+ is based on the following engineering criteria:

Product Status Alignment: The MAX4311EEE is classified as obsolete, while the MAX4311EEE+ maintains active product status. This distinction is critical for long-term supply chain continuity and component availability.

Regulatory Compliance: The MAX4311EEE+ achieves ROHS3 compliance, whereas the original MAX4311EEE is RoHS non-compliant. This compliance upgrade aligns with current environmental and regulatory requirements for electronic component manufacturing and distribution.

Electrical & Mechanical Equivalence: All electrical parameters, including bandwidth, slew rate, supply current, output current, and supply voltage ranges, are identical between the two parts. Mechanical compatibility is maintained through identical 16-SSOP package specifications and surface mount mounting type.

Functional Compatibility: Both parts perform the 4:1 multiplexer-amplifier function with identical circuit count and rail-to-rail output characteristics. No functional degradation or performance loss occurs with substitution.

Packaging Consideration: The MAX4311EEE+ is supplied in Tube packaging, whereas the original part number does not specify packaging format. This difference does not affect electrical or mechanical compatibility for circuit board assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the MAX4311EEE+ be used as a direct replacement for the MAX4311EEE in existing designs?

A: Yes. The MAX4311EEE+ is a direct substitute. All electrical parameters, package specifications, and functional characteristics are identical. The primary difference is product status (active vs. obsolete) and RoHS compliance level.

Q: What is the significance of the "+" suffix in the MAX4311EEE+ part number?

A: The "+" suffix indicates a variant of the base MAX4311 product. In this case, it denotes the active production version with updated compliance certifications (ROHS3) compared to the obsolete MAX4311EEE.

Q: Are there any performance differences between MAX4311EEE and MAX4311EEE+?

A: No. Both parts deliver identical electrical performance: 345 MHz bandwidth, 430 V/µs slew rate, 6.9 mA supply current, and 95 mA output current per channel. Voltage supply ranges and output characteristics are also identical.

Q: Is the 16-SSOP package compatible with existing PCB layouts designed for the MAX4311EEE?

A: Yes. Both parts use the identical 16-SSOP package with 0.154" width (3.90mm). Pin-to-pin compatibility and footprint dimensions are unchanged, allowing direct PCB layout reuse without modification.

Q: What is the difference in packaging between MAX4311EEE and MAX4311EEE+?

A: The MAX4311EEE+ is supplied in Tube packaging. The original MAX4311EEE packaging format is not specified in the provided data. This difference affects only component handling and storage; it does not impact electrical or mechanical performance.

Q: Are both parts suitable for new design implementations?

A: The MAX4311EEE+ is the appropriate choice for new designs. It maintains active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The MAX4311EEE is obsolete and should not be selected for new applications.

Q: What supply voltage ranges are supported by the MAX4311EEE+?

A: The MAX4311EEE+ supports single supply operation from 4V to 10.5V and dual supply operation from ±2V to ±5.25V. These ranges are identical to the original MAX4311EEE.

Q: Is the MAX4311EEE+ suitable for video amplifier applications?

A: Yes. The MAX4311EEE+ is designed for video amplifier applications with 4:1 multiplexer-amplifier functionality. The 345 MHz bandwidth and 430 V/µs slew rate support video signal processing requirements.
