TP3067ADW

Overview

The TP3067ADW is a monolithic serial interface CMOS codec and filter combo device manufactured by Texas Instruments. It integrates one analog-to-digital converter (ADC) and one digital-to-analog converter (DAC) within a single package. The component supports PCM audio formats with a maximum sampling rate of 256 kSPS. It operates on a single power supply voltage ranging from 4.75 V to 5.25 V. The device features a serial interface for data communication and includes two input channels and two output channels, each equipped with an amplifier. It is housed in a 20-pin SOIC package and is rated for an operating temperature range from -25 °C to +125 °C.

Feature Summary

• Integrated mono/stereo codec functionality combining ADC and DAC with built-in filters
• Supports high-speed serial interface for efficient data transfer
• Wide industrial operating temperature range suitable for harsh environments
• Single-supply operation simplifies power design requirements

Applications

• Industrial voice communication systems
• Automotive audio processing units
• Data acquisition systems requiring PCM encoding/decoding
• Telecommunications equipment interfaces

Procurement Notes

Verify the specific suffix 'ADW' corresponds to the desired temperature grade and packaging configuration against the official Texas Instruments datasheet. Confirm that the 20-pin SOIC footprint matches the target PCB layout. Ensure the 4.75V to 5.25V supply requirement aligns with the system power architecture before finalizing procurement.

Selection Notes

Select this component when a combined codec and filter solution is required for PCM applications. It is suitable for designs needing integrated amplification on both input and output channels. Consider the -25°C to +125°C temperature range if the application operates in extreme conditions. Verify compatibility with the host processor's serial interface protocol.

Part Context

The TP3067 series belongs to Texas Instruments' family of enhanced serial interface CMOS codecs. These devices are designed to replace discrete codec and filter implementations, reducing board space and complexity. The ADW variant specifically denotes the wide temperature grade and surface-mount SOIC packaging, distinguishing it from other thermal or package options within the same functional family.

Replacement Considerations

Check for direct pin-compatible alternatives such as the TP3067AN or TP3067BDW if different packaging or temperature grades are needed. Verify that any substitute maintains the 256 kSPS sampling rate and 20-pin SOIC form factor.
