MAX680CSA Equivalent & Substitute Parts

Part Overview

The MAX680CSA is a charge pump switching regulator IC manufactured by Analog Devices Inc./Maxim Integrated, designed to generate positive and negative dual rail outputs from a single input supply. This device produces fixed ±2Vin outputs at 10mA output current with an 8kHz switching frequency, housed in an 8-SOIC surface mount package. The MAX680CSA is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX680CSA is determined by strict equivalence across the following critical parameters:

• Topology & Function: Charge pump topology with ratiometric function
• Output Configuration: Positive and negative dual rail generation
• Electrical Specifications: Fixed ±2Vin output, 10mA output current, 8kHz switching frequency
• Input Voltage Range: 2V to 6V operation
• Package: 8-SOIC surface mount form factor
• Thermal Range: 0°C to 70°C operating temperature

The MAX680CSA+ qualifies as a direct substitute based on identical electrical performance, package geometry, and pinout compatibility. The primary distinction is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The MAX680CSA+ is the direct functional equivalent of the MAX680CSA. Both devices share identical electrical specifications, switching characteristics, and package geometry, ensuring pin-for-pin compatibility and circuit-level interchangeability.

The MAX680CSA+ is classified as an active product with ROHS3 compliance, whereas the MAX680CSA is obsolete and RoHS non-compliant. For new designs or production continuity, the MAX680CSA+ is the appropriate selection. Both devices maintain REACH Unaffected status and identical moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can MAX680CSA+ be used as a direct replacement for MAX680CSA in existing designs?

A: Yes. The MAX680CSA+ provides identical electrical performance, output voltage characteristics, switching frequency, and package pinout. No circuit modifications are required for substitution.

Q: What is the primary difference between MAX680CSA and MAX680CSA+?

A: The MAX680CSA+ is an active product with ROHS3 compliance, while the MAX680CSA is obsolete and RoHS non-compliant. Electrical and functional specifications are identical.

Q: Are there any thermal or operating condition differences?

A: No. Both devices operate across the same temperature range (0°C to 70°C) and maintain identical input voltage (2V to 6V) and output current (10mA) specifications.

Q: Does the packaging differ between these parts?

A: Both devices use the 8-SOIC (0.154", 3.90mm Width) surface mount package with identical pinout and mechanical dimensions.

Q: What is the significance of the "+" designation in MAX680CSA+?

A: The "+" suffix indicates a newer product revision with updated compliance certifications, specifically ROHS3 compliance, while maintaining full electrical and functional equivalence to the base MAX680CSA.
