TP5510N

Overview

The TP5510N is a full-duplex analog front-end (AFE) designed for consumer applications, manufactured by National Semiconductor. It integrates PCM codec functionality with mu-law encoding and decoding capabilities within a single functional unit. The device operates on a CMOS process and is housed in a 16-pin PDIP package. Key electrical parameters include an analog supply voltage range of 4.75V to 5.25V and a typical power consumption of 60 mW. It supports two channels for simultaneous transmission and reception.

Feature Summary

• Integrates full-duplex analog front-end processing with PCM codec capabilities
• Supports mu-law encoding and decoding standards for voice signals
• Operates as a single-function analog circuit within a 16-pin DIP package

Applications

• Consumer audio equipment requiring full-duplex communication
• PCM codec implementations in telecommunication devices
• Analog front-end processing for voice signal transmission and reception

Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets are now managed by Texas Instruments. Confirm the specific package variant matches the 16-pin PDIP requirement. Check for any obsolescence notices or lifecycle status changes from the current distributor. Ensure the component meets the specified mu-law standard if used in legacy systems. Validate that the active status aligns with long-term availability needs.

Selection Notes

Select this component when a dedicated full-duplex AFE with integrated PCM codec is required for consumer applications. Consider the 4.75V to 5.25V supply range compatibility with existing system power rails. Evaluate the 60 mW power consumption against thermal constraints. The 16-pin PDIP package suits through-hole mounting designs. Verify mu-law support if interfacing with standard telephony protocols.

Part Context

The TP5510N belongs to the TP5510 series of analog front-ends developed by National Semiconductor. It is part of a family of components designed for low-power, high-performance audio processing in consumer electronics. The 'N' suffix typically denotes the PDIP package option. This component represents a specialized solution for integrating analog and digital voice processing functions into a single chip.
