MAX4198ESA Equivalent & Substitute Parts

Part Overview

The MAX4198ESA is a differential amplifier integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This device is classified as a linear amplifier with rail-to-rail output capability, housed in an 8-SOIC surface mount package. The MAX4198ESA operates as a single-circuit differential amplifier within the Beyond-the-Rails™ series and is currently listed with obsolete product status. Due to its obsolete classification, identifying equivalent substitute parts with matching electrical and mechanical specifications is essential for design continuity and procurement planning.

Substitute Part Grouping Explanation

Substitution of the MAX4198ESA is determined by strict equivalence across all electrical performance parameters and mechanical packaging specifications. The substitute part must satisfy the following criteria:

Electrical Equivalence Requirements:

• Amplifier Type: Differential
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Slew Rate: 0.07 V/µs
• -3dB Bandwidth: 175 kHz
• Voltage - Input Offset: 30 µV
• Current - Supply: 45 µA
• Current - Output / Channel: 5.5 mA
• Voltage - Supply Span: 2.7 V to 7.5 V
• Operating Temperature Range: -40°C to 85°C

Mechanical Equivalence Requirements:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 8-SOIC

The MAX4198ESA+ meets all specified electrical and mechanical parameters and is therefore classified as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The MAX4198ESA+ is the direct equivalent substitute for the MAX4198ESA. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical performance specifications and mechanical packaging.

Key Advantages of MAX4198ESA+ for New Designs:

The MAX4198ESA+ maintains active product status, ensuring continued availability and manufacturer support. The substitute part achieves ROHS3 compliance, whereas the original MAX4198ESA is RoHS non-compliant. This compliance improvement is significant for applications subject to environmental regulations and procurement standards that mandate RoHS-compliant components.

Compatibility Confirmation:

All electrical parameters—including slew rate, bandwidth, input offset voltage, supply current, output current, supply voltage range, and operating temperature range—are identical between the two parts. The 8-SOIC surface mount package dimensions and pinout are equivalent, enabling direct substitution without circuit board redesign or layout modifications.

Procurement Considerations:

The MAX4198ESA is classified as obsolete, which may result in limited inventory availability and potential supply chain discontinuation. The MAX4198ESA+ is actively manufactured and stocked, providing superior long-term availability and procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the MAX4198ESA+ be used as a direct replacement for the MAX4198ESA in existing designs?

A: Yes. The MAX4198ESA+ is electrically and mechanically equivalent to the MAX4198ESA. All performance parameters, including slew rate, bandwidth, input offset voltage, supply current, output current, and supply voltage range, are identical. The 8-SOIC package footprint is the same, allowing direct substitution without circuit modifications.

Q: What is the difference between MAX4198ESA and MAX4198ESA+?

A: The primary differences are product status and regulatory compliance. The MAX4198ESA is obsolete and RoHS non-compliant, while the MAX4198ESA+ is an active product with ROHS3 compliance. Electrically and mechanically, both parts are identical.

Q: Why should I transition from MAX4198ESA to MAX4198ESA+?

A: The MAX4198ESA is obsolete, which creates supply chain risk and potential unavailability. The MAX4198ESA+ is actively manufactured, ensuring reliable procurement. Additionally, the MAX4198ESA+ meets ROHS3 environmental compliance standards, which is required for many applications and regulatory jurisdictions.

Q: Are there any packaging differences between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. The MAX4198ESA is supplied in standard packaging, while the MAX4198ESA+ is supplied in tube packaging. The physical component dimensions and pinout are identical.

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

A: Both the MAX4198ESA and MAX4198ESA+ have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without moisture control requirements.

Q: Are these parts suitable for military or aerospace applications?

A: Both parts operate across the -40°C to 85°C temperature range. Refer to the manufacturer's detailed specifications and application notes for specific military or aerospace qualification requirements.
