Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX492C/D is determined by electrical and mechanical parameter equivalence within the general purpose operational amplifier category. The substitute component must maintain identical specifications across the following critical parameters:

• Dual-circuit (2-circuit) configuration
• Rail-to-rail output capability
• Slew rate of 0.2 V/µs
• Gain bandwidth product of 500 kHz
• Input bias current of 25 nA
• Input offset voltage of 200 µV
• Supply current of 150 µA per channel
• Output current capability of 30 mA per channel
• Supply voltage range of 2.7 V to 6 V
• Operating temperature range of 0°C to 70°C
• Surface mount technology
• ROHS3 compliance

The MAX492CSA+ qualifies as a direct substitute based on complete electrical parameter equivalence. The primary distinction is packaging format: the substitute transitions from die-level integration to an 8-SOIC surface mount package, enabling standard PCB assembly integration while preserving all functional specifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX492CSA+ is the designated substitute for the obsolete MAX492C/D based on complete electrical parameter equivalence and active product status. Both components are manufactured by Analog Devices Inc./Maxim Integrated and share the same base product number (MAX492), confirming design lineage and functional compatibility.

Selection of the MAX492CSA+ provides the following advantages:

• Active Product Status: The substitute maintains current manufacturing and supply chain support, eliminating obsolescence risk associated with the MAX492C/D.
• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.
• Electrical Equivalence: All functional parameters remain identical, ensuring direct functional substitution in circuit applications.
• Packaging Integration: The transition from die to 8-SOIC package enables standard surface mount PCB assembly, improving manufacturing accessibility and reducing integration complexity compared to die-level handling.

The MAX492CSA+ is available in active inventory (1450 pieces), ensuring supply continuity for production and development requirements.

Frequently Asked Questions (FAQ)

Q: Can the MAX492CSA+ directly replace the MAX492C/D in all applications?

A: The MAX492CSA+ provides complete electrical parameter equivalence to the MAX492C/D. The primary difference is packaging format: the substitute uses an 8-SOIC surface mount package instead of die form. Applications requiring die-level integration must evaluate package compatibility independently. All electrical specifications, including slew rate, bandwidth, supply current, and output current, are identical.

Q: What is the significance of the product status change from Obsolete to Active?

A: The MAX492C/D is classified as obsolete, indicating discontinued manufacturing and limited supply availability. The MAX492CSA+ maintains active product status with current manufacturing support. This transition ensures long-term design viability and supply chain reliability for new designs and production continuity.

Q: Are there compliance differences between the two components?

A: Both the MAX492C/D and MAX492CSA+ maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both components. No compliance differentiation exists between the main part and substitute.

Q: What packaging considerations apply to the MAX492CSA+ substitute?

A: The MAX492CSA+ uses an 8-SOIC (0.154", 3.90mm Width) surface mount package, compared to the die package of the MAX492C/D. This package format is compatible with standard PCB assembly processes and automated placement equipment. Pin configuration and electrical interface remain consistent with the base MAX492 product family.

Q: Is the supply voltage range identical between both components?

A: Yes. Both the MAX492C/D and MAX492CSA+ operate across an identical supply voltage range of 2.7 V to 6 V, supporting low-power and battery-powered applications without modification.

Q: What is the operating temperature range for the substitute component?

A: The MAX492CSA+ maintains the same operating temperature range as the MAX492C/D: 0°C to 70°C. No temperature performance differentiation exists between the components.
