Overview
The W681360RG TR is a single-channel voiceband audio codec manufactured by Nuvoton Technology Corporation. It integrates one analog-to-digital converter (ADC) and one digital-to-analog converter (DAC) with a resolution of 13 bits. The device operates on a PCM interface for digital audio data transmission. It supports an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 2.7 V to 5.25 V. The component is designed for surface mount installation in a 32-VFQFN package, specifically the 32-QFN (5.2x5.2) variant. It functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Single-channel linear voiceband codec architecture
- Integrated 13-bit ADC and DAC conversion
- Standard PCM digital audio interface compatibility
Applications
- Voice communication systems requiring single-channel audio processing
- Telephony equipment utilizing PCM interfaces
- Industrial control systems with voiceband signal requirements
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm current manufacturing status as the base model W681360YG is listed as obsolete. Ensure the supplier provides valid RoHS compliance documentation. Check for moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Validate that the 32-QFN package dimensions match the design footprint.
Selection Notes
Select this component for applications requiring a dedicated single-channel voice codec with 13-bit resolution. Ensure the system power supply accommodates the 2.7 V to 5.25 V range for both analog and digital domains. Verify that the host processor supports the required PCM interface protocol. Consider the 32-VFQFN package size constraints for the PCB layout. Compare against the W681360SG if a different package type is preferred.
Part Context
This part belongs to the Nuvoton W681360 series of voiceband codecs. The series includes variants such as W681360YG, W681360SG, and W681360WG. The W681360YG is noted as obsolete, with the W681360RG identified as a similar available alternative. The series focuses on single-channel linear codec functionality for voiceband applications.
Replacement Considerations
The W681360RG is listed as a similar replacement for the obsolete W681360YG. Verify pinout and electrical specifications against the original design requirements before substitution.
