TCM129C18N

Codecs Overview

The TCM129C18N is a combo codec and filter integrated circuit manufactured by Texas Instruments. It is designed for PCM audio applications, combining analog-to-digital and digital-to-analog conversion with filtering functions in a single package. The device operates within a temperature range of -40°C to +85°C. It utilizes a standard 16-pin Plastic Dual In-Line Package (PDIP) with dimensions of 19.3 mm in length, 6.35 mm in width, and 3.9 mm in thickness. The component supports companding laws suitable for telecommunications and industrial audio interfaces.

Codecs Feature Summary

• Integrates PCM codec and filter functions into a single IC
• Supports analog interface requirements for DSP systems
• Operates reliably across extended industrial temperature ranges

Codecs Applications

• PCM audio transmission systems
• Industrial communication interfaces
• DSP-based audio processing units

Codecs Procurement Notes

Verify the specific suffix designation upon ordering, as variations such as TCM129C18N-10 may indicate distinct operational parameters or packaging configurations. Confirm that the required PDIP package matches the target PCB footprint. Ensure compatibility with existing companding standards and voltage levels before integration into the final design.

Codecs Selection Notes

Select this component when a combined codec and filter solution is required for PCM signal processing. Consider the 16-pin DIP form factor for through-hole mounting constraints. Evaluate the operating temperature range against environmental conditions. Verify that the analog interface specifications align with the connected DSP or microcontroller architecture.
