TLC320AD545PTR

Codecs Overview

The TLC320AD545PTR is a single-channel data and fax codec manufactured by Texas Instruments. It features a 16-bit resolution with one analog-to-digital converter (ADC) and one digital-to-analog converter (DAC). The device utilizes a serial interface for data transmission. It operates within an analog supply voltage range of 4.75 V to 5.5 V and a digital supply voltage range of 4.5 V to 5.5 V. The component supports a sampling rate of 22.05 kHz and delivers a signal-to-noise ratio of 89 dB for both the ADC and DAC channels. It is housed in a 48-LQFP package measuring 7x7 mm, designed for surface-mount installation.

Codecs Feature Summary

• Integrates a single-channel audio codec with dedicated ADC and DAC functions for data and fax applications.
• Supports high-fidelity conversion through 16-bit resolution and sigma-delta modulation architecture.
• Utilizes a standard serial interface for efficient digital communication with host processors.

Codecs Applications

• Data modem systems requiring integrated audio processing
• Fax machine interfaces for signal encoding and decoding
• Single-channel voice communication devices

Codecs Procurement Notes

Verify the specific ordering suffix and package variant against current availability, as distribution channels may list obsolete or alternative stock sources. Confirm that the 48-LQFP footprint matches your PCB design requirements. Ensure compliance with RoHS standards if required for your manufacturing process. Check moisture sensitivity levels for proper storage and handling procedures before assembly.

Codecs Selection Notes

Select this component when a single-channel solution is sufficient for data or fax applications. Consider the 48-LQFP package size for board space constraints. Verify that the 22.05 kHz sampling rate meets the bandwidth requirements of the target application. Ensure the power supply voltages align with the specified 4.75 V to 5.5 V ranges for stable operation.
