The W681512SG from Nuvoton Technology is a general-purpose, single-channel PCM CODEC. It features pin-selectable μ-Law or A-Law companding and is compliant with the ITU G.712 specification. This device operates from a single +5V power supply, making it suitable for various voice over network applications.
Key electrical characteristics include an 8-bit resolution, a PCM audio interface, and support for master clock rates from 256 kHz to 4.096 MHz. It also includes an on-chip precision voltage reference and power amplifiers capable of driving 300 Ω loads. The fully-differential analog circuit design enhances noise reduction and power supply rejection.
Performance is specified over the industrial temperature range of -40°C to +85°C. The W681512SG is available in a 20-pin SOP package, suitable for surface mount applications. Its design incorporates digitization and reconstruction of voice signals, along with necessary band-limiting and smoothing filters compliant with ITU G.712.
Applications include VoIP, digital telephone systems, wireless voice devices, and broadband access equipment.
