Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX457CSA is determined by strict equivalence across the following critical parameters:

Electrical Performance Parameters:

• -3dB Bandwidth: 70 MHz
• Slew Rate: 300 V/µs
• Current - Supply: 35 mA
• Current - Output / Channel: 20 mA
• Voltage - Supply, Single/Dual (±): ±4.5V ~ 5.5V
• Number of Circuits: 2

Physical and Mechanical Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Manufacturer and Base Product:

• Manufacturer: Analog Devices Inc./Maxim Integrated
• Base Product Number: MAX457

Substitute parts must match all electrical performance parameters and physical specifications. Variations in product status, packaging format, or compliance certifications do not affect functional equivalence when all electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

The MAX457CSA+ is a direct functional equivalent to the MAX457CSA. Both parts share identical electrical performance specifications and physical package dimensions. The primary differences are product status and compliance certifications.

MAX457CSA+ Advantages:

• Active product status ensures continued manufacturer support and availability
• ROHS3 compliance satisfies environmental and regulatory requirements for new designs
• Tube packaging format provides standard handling and storage compatibility

MAX457CSA Considerations:

• Classified as obsolete; long-term availability cannot be assured
• RoHS non-compliant status may restrict use in applications with regulatory requirements

For new designs or production requiring long-term component availability and regulatory compliance, the MAX457CSA+ is the appropriate selection. For legacy system maintenance where the original MAX457CSA specification must be maintained, the MAX457CSA remains functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can MAX457CSA+ be used as a direct replacement for MAX457CSA in existing designs?

A: Yes. The MAX457CSA+ is electrically and mechanically equivalent to the MAX457CSA. All electrical performance parameters, supply voltage ranges, output current ratings, bandwidth, and slew rate specifications are identical. The 8-SOIC package dimensions and surface mount configuration are unchanged. Substitution requires no circuit modifications.

Q: What is the difference between MAX457CSA and MAX457CSA+?

A: The parts are functionally identical. Differences exist only in product status, compliance certifications, and packaging format. The MAX457CSA is obsolete and RoHS non-compliant. The MAX457CSA+ is an active product with ROHS3 compliance and is supplied in tube packaging.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts operate at identical specifications: 70 MHz bandwidth, 300 V/µs slew rate, 35 mA supply current, 20 mA output current per channel, and ±4.5V to ±5.5V supply voltage range.

Q: Does the packaging format affect compatibility?

A: No. Both parts use the same 8-SOIC (0.154", 3.90mm Width) surface mount package. The packaging format difference (tube versus unspecified) relates only to shipment and storage; it does not affect component functionality or PCB assembly compatibility.

Q: Is the MAX457CSA+ suitable for new product designs?

A: Yes. The MAX457CSA+ is an active product with ROHS3 compliance, making it appropriate for new designs. The MAX457CSA, being obsolete, is not recommended for new designs where long-term availability is required.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply.
