W6810IEG

Overview

The W6810IEG is an 8-bit PCM voiceband codec manufactured by Nuvoton Technology Corporation. It features a single-channel analog-to-digital converter (ADC) and digital-to-analog converter (DAC). The device operates within a supply voltage range of 4.5 V to 5.5 V, with maximum ratings up to 5.5 V. It supports standard PCM interface protocols for audio data transmission. The component is housed in a 20-pin Dual In-Line Package (DIP) with a pitch of 0.300 inches (7.62 mm). It is designed for industrial temperature ranges, functioning between -40°C and +85°C. The unit complies with RoHS standards and exhibits Moisture Sensitivity Level 1.

Feature Summary

• Single-channel voiceband audio conversion capability
• Standard PCM interface compatibility
• Industrial-grade wide operating temperature range
• RoHS compliant lead-free construction

Applications

• Voice communication systems requiring single-channel processing
• Telecommunications equipment utilizing PCM interfaces
• Industrial control systems with audio monitoring requirements
• Embedded voiceband signal processing applications

Procurement Notes

Verify the specific package variant upon ordering, as the W6810 series includes both surface mount and through-hole options. Confirm that the 20-DIP configuration matches the target PCB footprint. Ensure design compliance with the specified 4.5 V to 5.5 V power supply constraints. Check current lifecycle status, as older components may be subject to discontinuation notices. Validate RoHS certification documentation for regulatory adherence in final assemblies.

Selection Notes

Select this component when a single-channel 8-bit voiceband codec is required for PCM-based audio interfaces. The 20-DIP package is suitable for through-hole assembly or prototyping environments where surface mount technology is not preferred. Consider the operational temperature range if the application involves harsh industrial conditions. Verify that the system architecture supports the specific voltage levels and interface timing requirements defined for this codec family.

Part Context

The W6810IEG belongs to the W6810 series of voiceband codecs produced by Nuvoton Technology Corporation. This series provides integrated analog-to-digital and digital-to-analog conversion for voice signals. The IEG suffix specifically denotes the 20-pin DIP package variant, distinguishing it from other package types like SSOP or TSSOP available within the same functional family. These devices are designed for reliable performance in telecommunications and industrial audio applications.

Replacement Considerations

Direct substitutes include other W6810 series variants such as W6810IRG, which offers the same functional specifications but utilizes an SSOP-20 surface mount package instead of the through-hole DIP format. When replacing, ensure the mechanical footprint and pinout compatibility match the existing board layout. Functional equivalence remains consistent across the series, though packaging differences require physical verification.
