Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS5530-CSZ is determined by strict parametric equivalence across the following critical specifications:

• 24-bit resolution and 3.84k samples per second sampling rate
• Single differential input configuration
• Sigma-Delta architecture with external reference
• SPI digital interface protocol
• Identical supply voltage ranges (±3V, 0V ~ 5V analog; 2.7V ~ 5.5V digital)
• Operating temperature range of -20°C ~ 70°C
• 20-SSOP surface mount package with identical physical dimensions
• Matching moisture sensitivity level (MSL 3)

The CS5530-ISZ meets all these parameters and qualifies as a parametric equivalent substitute. The primary distinction between these parts is product status and packaging format, not functional or electrical characteristics.
