Substitute Part Grouping Explanation
Substitution eligibility for the TLC320AC01CFN is determined by strict alignment of the following critical parameters:
- Resolution: 14-bit audio processing capability
- ADC/DAC Configuration: Single-channel ADC and single-channel DAC
- Data Interface: Serial communication protocol
- Supply Voltage Ranges: Analog 4.5V ~ 5.5V and Digital 4.5V ~ 5.5V
- Operating Temperature Range: 0°C ~ 70°C
- Package Type: 28-PLCC (11.51x11.51) surface mount configuration
- Compliance Standards: ROHS3 Compliant, REACH Unaffected
The TLC320AC02CFN meets all these criteria and is classified as a manufacturer-recommended substitute. Both parts share identical electrical specifications, package dimensions, and regulatory compliance status, making them functionally interchangeable within the specified operating parameters.
