Substitute Part Grouping Explanation
Substitution eligibility for the AD7715ARU-5 is determined by strict equivalence across the following critical parameters:
- Resolution & Architecture: 16-bit sigma-delta conversion
- Input Configuration: Single differential input with 1 A/D converter
- Sampling Performance: 500 samples per second
- Signal Conditioning: Integrated PGA
- Interface Compatibility: SPI and DSP protocols
- Supply Requirements: 5V analog, 3V–5.25V digital
- Thermal Range: -40°C to 85°C operation
- Physical Form Factor: 16-TSSOP surface mount package
The AD7715ARUZ-5 meets all these criteria and is therefore a direct functional equivalent. The primary distinction is product status and packaging format.
