Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4448ESE is determined by strict equivalence across the following critical parameters:

Electrical Performance Parameters:

• -3dB Bandwidth: 330 MHz
• Slew Rate: 4300 V/µs
• Current - Supply: 46 mA
• Current - Output / Channel: 130 mA
• Voltage - Supply, Single/Dual (±): ±4.5V ~ 5.5V
• Output Type: Differential
• Number of Circuits: 1

Physical & Mechanical Parameters:

• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Functional Parameters:

• Applications: Driver
• Category: Linear, Amplifiers

Substitute parts must match all electrical performance parameters, physical package specifications, and functional classification. Variations in product status, compliance certifications, or packaging format (tube vs. tape) do not disqualify substitution when electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

MAX4448ESE+ as Direct Substitute:

The MAX4448ESE+ is a direct electrical and mechanical equivalent to the MAX4448ESE. All critical performance parameters—bandwidth, slew rate, supply current, output current, supply voltage range, output type, circuit count, and package specifications—are identical between the two parts.

Key Differentiation Factors:

1. Product Status: The MAX4448ESE+ maintains Active product status, ensuring continued manufacturer support, availability, and potential future design improvements. The MAX4448ESE is Obsolete, indicating end-of-life status.

2. RoHS Compliance: The MAX4448ESE+ is ROHS3 Compliant, meeting current environmental and regulatory requirements for electronic components in many jurisdictions. The MAX4448ESE is RoHS non-compliant, which may present regulatory constraints for new designs or applications subject to RoHS directives.

3. Packaging Format: The MAX4448ESE+ is supplied in Tube packaging, while the original part number does not specify a packaging format. Both formats are compatible with standard surface mount assembly processes.

Selection Guidance:

For applications requiring regulatory compliance with RoHS3 standards or long-term supply chain stability, the MAX4448ESE+ is the appropriate selection. For legacy systems or applications where RoHS compliance is not mandated, either part is electrically and mechanically interchangeable. The identical electrical specifications ensure drop-in compatibility without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q1: Are MAX4448ESE and MAX4448ESE+ electrically identical?

A: Yes. Both parts share identical electrical specifications: 330 MHz bandwidth, 4300 V/µs slew rate, 46 mA supply current, 130 mA output current per channel, ±4.5V to ±5.5V supply voltage range, and differential output configuration. No circuit modifications are required for substitution.

Q2: Can MAX4448ESE+ be used as a direct replacement in existing designs?

A: Yes. The MAX4448ESE+ is mechanically and electrically compatible with the MAX4448ESE. Both use the 16-SOIC surface mount package with identical pinout and electrical characteristics. No PCB redesign or component repositioning is necessary.

Q3: What is the significance of the RoHS compliance difference?

A: The MAX4448ESE+ is ROHS3 Compliant, meaning it meets restrictions on hazardous substances (lead, cadmium, mercury, etc.) required by RoHS directives. The MAX4448ESE is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the MAX4448ESE+ is the appropriate choice.

Q4: Why is the MAX4448ESE classified as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this part number. The MAX4448ESE+ represents the current active equivalent, ensuring ongoing availability and manufacturer support.

Q5: Are there any performance differences between the two parts?

A: No. All performance parameters—bandwidth, slew rate, current specifications, voltage range, and output characteristics—are identical. Performance differences do not exist between these parts.

Q6: What is the difference between Tube and unspecified packaging formats?

A: Tube packaging is a standard format for surface mount components, providing organized component presentation for automated assembly equipment. Both packaging formats are compatible with standard pick-and-place assembly processes. The packaging format does not affect electrical performance or mechanical compatibility.

Q7: Can MAX4448ESE be substituted with other video amplifier drivers?

A: Substitution with other components requires matching all specified electrical parameters (bandwidth, slew rate, current ratings, voltage range), output type (differential), circuit count (1), and package specifications (16-SOIC). Only parts meeting all these criteria are valid substitutes. The MAX4448ESE+ is the only listed equivalent for this part number.

Q8: What is the Moisture Sensitivity Level (MSL) significance?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. Both the MAX4448ESE and MAX4448ESE+ share this specification, eliminating any moisture-related compatibility concerns.
