TP3057N/NOPB

Codecs Overview

The TP3057N/NOPB is a monolithic serial interface CODEC and filter combo device from Texas Instruments. It integrates an A-law PCM codec with analog filters for full-duplex voice communication. The component operates on dual ±5V power supplies and supports both synchronous and asynchronous modes. It features a 16-pin PDIP package, suitable for through-hole mounting. The device functions as a combined analog-to-digital and digital-to-analog converter within the enhanced serial interface family.

Codecs Feature Summary

• Integrates A-law PCM encoding and decoding with integrated analog filtering capabilities
• Supports full-duplex voice transmission via serial interface
• Operates in both synchronous and asynchronous modes

Codecs Applications

• Digital telephone systems
• Voice processing equipment
• Telecommunications interfaces

Codecs Procurement Notes

Verify the specific manufacturer source, as TP3057N/NOPB may be distributed by Rochester Electronics or Texas Instruments. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the PDIP-16 package matches the target PCB footprint requirements before finalizing procurement orders.

Codecs Selection Notes

Select this component when a combined CODEC and filter solution is required for A-law PCM applications. Verify that the ±5V dual supply voltage aligns with the system design. Consider the PDIP-16 package constraints if surface mount alternatives like the SOIC version are preferred for automated assembly processes.

Codecs Part Context

This part belongs to the Enhanced Serial Interface CODEC/Filter COMBO Family. It serves as a legacy alternative to newer mixed-signal ICs. The device simplifies circuit design by combining audio conversion and filtering into a single chip, reducing component count in traditional telephony hardware designs.

Codecs Replacement Considerations

The TP3057BDW offers a surface-mount SOIC-16 alternative. The TP3057WM/NOPB provides a wider operating temperature range. Verify pin compatibility and electrical specifications before substituting these variants.
