MAX4449ESE Equivalent & Substitute Parts

Part Overview

The MAX4449ESE is a video amplifier driver integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This linear amplifier operates as a single-channel differential output driver designed for high-speed signal conditioning applications. The device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and component procurement. The MAX4449ESE remains available in limited inventory (864 pieces) but is no longer in active production, making substitute part identification critical for long-term supply chain management.

Substitute Part Grouping Explanation

Substitute part identification for the MAX4449ESE is based on strict electrical and mechanical parameter matching within the linear amplifier driver category. The primary substitution criterion is functional equivalence across all specified electrical parameters: bandwidth, slew rate, supply current, output current capability, and supply voltage range. Secondary criteria include package compatibility (16-SOIC surface mount form factor), circuit count (single channel), and output configuration (differential).

The MAX4449ESE+ qualifies as a direct substitute based on identical electrical specifications across all measured parameters. Both devices operate within the same bandwidth (400 MHz), slew rate (6500 V/µs), supply current (46 mA), output current per channel (130 mA), and supply voltage range (±4.5V to 5.5V). Both are packaged in 16-SOIC surface mount configuration with single differential output driver topology.

Key parameters determining substitution eligibility:

• Bandwidth: 400 MHz (exact match required)
• Slew Rate: 6500 V/µs (exact match required)
• Supply Current: 46 mA (exact match required)
• Output Current: 130 mA per channel (exact match required)
• Supply Voltage: ±4.5V to 5.5V (exact match required)
• Package: 16-SOIC surface mount (exact match required)
• Output Configuration: Differential, single circuit (exact match required)

Parameter Comparison

Engineering Selection Recommendations

The MAX4449ESE+ is the direct functional equivalent for the obsolete MAX4449ESE. Selection of the MAX4449ESE+ is supported by three primary engineering factors:

Product Status: The MAX4449ESE is classified as obsolete with limited remaining inventory (864 pieces). The MAX4449ESE+ maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: The MAX4449ESE is RoHS non-compliant, while the MAX4449ESE+ achieves ROHS3 compliance. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the MAX4449ESE+ satisfies regulatory obligations.

Electrical and Mechanical Equivalence: All specified electrical parameters are identical between the two devices. The 16-SOIC surface mount package, differential output configuration, bandwidth (400 MHz), slew rate (6500 V/µs), supply current (46 mA), output current (130 mA), and supply voltage range (±4.5V to 5.5V) are functionally equivalent. Pin-to-pin compatibility and circuit board layout requirements remain unchanged.

Packaging Consideration: The MAX4449ESE+ is supplied in tube packaging, whereas the original part number does not specify packaging format. Tube packaging is standard for active production components and does not affect electrical performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the MAX4449ESE+ be used as a direct replacement for the MAX4449ESE in existing designs?

A: Yes. The MAX4449ESE+ is electrically and mechanically equivalent to the MAX4449ESE across all specified parameters. Pin configuration, package footprint (16-SOIC), and electrical performance are identical. No circuit modifications or board redesign are required.

Q: What is the difference between MAX4449ESE and MAX4449ESE+?

A: The primary differences are product status and regulatory compliance. The MAX4449ESE is obsolete and RoHS non-compliant. The MAX4449ESE+ is in active production and ROHS3 compliant. Electrical specifications and package format are identical.

Q: Why is the MAX4449ESE classified as obsolete?

A: The MAX4449ESE has been discontinued by the manufacturer. The MAX4449ESE+ represents the active production equivalent and is the recommended part for new designs and ongoing procurement.

Q: Are there any compatibility issues when switching from MAX4449ESE to MAX4449ESE+?

A: No compatibility issues exist. Both devices share identical electrical parameters, pin assignments, and 16-SOIC package dimensions. Direct substitution is supported without circuit modifications.

Q: What is the significance of ROHS3 compliance on the MAX4449ESE+?

A: ROHS3 compliance indicates the device meets Restriction of Hazardous Substances Directive requirements. This is relevant for applications subject to EU regulations or customer specifications requiring RoHS compliance. The MAX4449ESE does not meet these requirements.

Q: Is the tube packaging of the MAX4449ESE+ suitable for automated assembly?

A: Yes. Tube packaging is standard for surface mount components and is compatible with automated pick-and-place assembly equipment. Tube format does not affect electrical performance or board-level integration.

Q: What are the key electrical parameters that define substitution eligibility for the MAX4449ESE?

A: Substitution eligibility is determined by matching bandwidth (400 MHz), slew rate (6500 V/µs), supply current (46 mA), output current per channel (130 mA), supply voltage range (±4.5V to 5.5V), package format (16-SOIC), and output configuration (differential, single circuit). All parameters must match exactly.

Q: Can the MAX4449ESE be used in new designs?

A: The MAX4449ESE is obsolete and not recommended for new designs. The MAX4449ESE+ is the active production equivalent and should be specified for all new applications.
