W681512WG TR

Overview

The W681512WG TR is a single-channel voiceband audio codec manufactured by Nuvoton Technology Corporation. It operates on a single 4.5V to 5.5V power supply and features an 8-bit resolution with one ADC and one DAC. The device utilizes a PCM interface for data transmission and is housed in a 20-TSSOP surface-mount package. It supports differential outputs and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports μ-law or A-law companding via pin selection
• Integrates built-in phase-locked loop (PLL)
• Provides differential output capability
• Complies with ITU G.712 specifications

Applications

• PCM audio systems requiring voiceband processing
• Digital telephony equipment
• Voice signal digitization and reconstruction circuits

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging, distinct from tube-packaged variants like W681512WG. Confirm current lifecycle status as sources indicate this specific reel variant may be discontinued or restricted. Ensure RoHS3 compliance matches project requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-channel 8-bit voiceband codec with differential outputs is required. Verify that the TSSOP-20 package fits the PCB layout constraints. Ensure the system design accommodates the 4.5V to 5.5V operating voltage range and PCM interface timing requirements.

Part Context

This part belongs to the W681512 family of general-purpose single-channel PCM codecs. Variants differ primarily by packaging type, such as SOP, SSOP, or TSSOP, and delivery format. The core functionality remains consistent across the family, adhering to standard voiceband codec specifications.

Replacement Considerations

Publicly confirmed substitutes include other W681512 family members with different packages, such as W681512SG or W681512RG, provided the package change is acceptable for the design.
