TP3067BDW

Overview

The TP3067BDW is a monolithic CMOS codec and filter combo integrated circuit manufactured by Texas Instruments. It features a serial interface for PCM audio processing, integrating one analog-to-digital converter (ADC) and one digital-to-analog converter (DAC). The device operates within a supply voltage range of 4.75V to 5.25V and supports sampling rates up to 256 kSPS. Designed for robust performance, it functions across an extended temperature range from -25°C to 125°C. The component is housed in a 20-pin SOIC package, providing a compact solution for full-duplex audio applications requiring high integration.

Feature Summary

• Integrates both codec and filter functionalities into a single monolithic CMOS chip
• Supports serial interface communication for efficient data transfer
• Provides full-duplex operation with dedicated ADC and DAC channels
• Operates reliably across an extended industrial temperature range

Applications

• Telecommunications equipment requiring PCM codec functionality
• Industrial audio processing systems needing wide temperature tolerance
• Embedded voice communication modules utilizing serial interfaces

Procurement Notes

Verify the specific suffix BDW corresponds to the 20-pin SOIC surface-mount package and the extended temperature grade (-25°C to 125°C). Confirm that the device meets RoHS compliance standards if required for your assembly process. Ensure compatibility with the 4.75V to 5.25V power supply rails before integration into the final design.

Selection Notes

Select this component when a combined codec and filter solution is needed to reduce board space and component count. It is suitable for designs requiring serial interface connectivity and operation in harsh thermal environments. Compare against standard commercial grade parts if the extended temperature range is not necessary for the specific application requirements.

Part Context

This part belongs to the TP3067 family of enhanced serial interface CMOS CODEC/Filter combos. It shares functional similarities with other members like the TP3067WM/NOPB but differs in package type and temperature rating. The BDW suffix specifically denotes the SOIC package variant, distinguishing it from DIP or wider SOIC options available in the same product line.

Replacement Considerations

The TP3067BN is a PDIP-20 alternative offering similar MU-LAW codec functionality. Verify pinout compatibility between the SOIC and DIP packages before substitution. Other family members such as TP3067ADW may serve as direct replacements if package differences are acceptable.
