TP3054N

Codecs Overview

The TP3054N is a CMOS CODEC/filter combo device from the Enhanced Serial Interface family, originally manufactured by National Semiconductor and now under Texas Instruments. It interfaces analog audio bandwidth signals to digital processors via MICROWIRE/PLUS synchronous serial communication. The component integrates analog-to-digital and digital-to-analog conversion capabilities within a single package. Key electrical parameters include an operating voltage range of 2.7V to 5.5V, a typical supply current of 15mA at 5V, and a dynamic range of 86dB. It supports sampling rates up to 48kHz with a 16-bit resolution for both input and output channels.
