Overview
The W681512SG TR is a single-channel voiceband audio CODEC manufactured by Nuvoton Technology Corporation. It operates within a supply voltage range of 4.5 V to 5.5 V, with maximum and minimum limits of 5.5 V and 4.5 V respectively. The device features an 8-bit resolution and utilizes a PCM interface for data communication. Internally, it integrates one Analog-to-Digital Converter (ADC) and one Digital-to-Analog Converter (DAC). Designed for surface-mount installation, the component is housed in a SOP-20 package. It supports reliable operation across an extended industrial temperature range from -40°C to +85°C.
Feature Summary
- Single-channel voiceband audio processing capability
- Differential output configuration for improved signal integrity
- Integrated ADC and DAC for direct analog-digital conversion
- PCM interface compatibility for standard digital audio systems
Applications
- Voiceband communication systems
- Telephony interface circuits
- Audio codec modules requiring differential outputs
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix 'TR' indicates the reel packaging format. Check current availability status as the product lifecycle may be discontinued or limited. Ensure the SOP-20 package matches the design footprint requirements before procurement.
Selection Notes
Select this component when a single-channel voiceband codec with differential output is required. Ensure the system power supply remains within the 4.5 V to 5.5 V operating range. Verify that the SOP-20 package fits the PCB layout constraints. Confirm compatibility with the target PCM interface protocol and required 8-bit resolution for the specific audio application.
Part Context
This part belongs to the Nuvoton Audio CODECs product line under Interface ICs. It is specifically categorized as a Single Channel Voice Codec. The manufacturer is Nuvoton Technology Corporation. The component falls under the broader category of Interface ICs designed for audio signal processing applications.
Replacement Considerations
The W681512RG is a related variant offering identical functional specifications but packaged in SSOP-20 instead of SOP-20. Verify pinout compatibility and physical footprint differences before substitution. Both parts share the same electrical characteristics and interface protocols.
