TLC320AD52CPT

Codecs Overview

The TLC320AD52CPT is a single-channel audio codec manufactured by Texas Instruments, housed in a 48-pin Plastic Quad Flat Pack (PT) package. It provides 16-bit oversampling sigma-delta analog-to-digital and digital-to-analog conversion with a typical signal-to-noise ratio of 89 dB for both ADC and DAC paths. The device operates on a single 5-V power supply or separate 5-V analog and 3-V digital supplies, supporting a maximum conversion rate of 22.05 kHz. It features a synchronous serial interface, programmable gain amplifiers, an internal phase-locked loop, and supports one slave device in master mode.

Codecs Feature Summary

• Integrates 16-bit sigma-delta ADC and DAC channels with high-resolution signal processing capabilities
• Supports master-slave configurations allowing connection to one external slave device
• Includes programmable input and output gain control alongside hardware and software power-down modes
• Features an internal phase-locked loop and dedicated monitor amplifier for signal verification

Codecs Applications

• V.34+ modem interfaces requiring high-fidelity audio signal conversion
• Business audio applications utilizing general-purpose analog interface circuits
• Digital signal processor systems requiring synchronous serial communication protocols

Codecs Procurement Notes

Verify the specific suffix CPT corresponds to the plastic quad flat pack package and commercial temperature range during sourcing. Confirm that the component meets RoHS compliance standards as indicated in manufacturer documentation. Ensure availability through authorized distributors given potential lifecycle changes. Validate pin compatibility with existing PCB layouts before procurement.

Codecs Selection Notes

Select this component when a single-channel 16-bit codec with integrated sigma-delta modulation is required. Consider the PT package dimensions for board space constraints. Evaluate the need for master-slave synchronization if multiple codecs are used in the system. Verify power supply requirements align with available 5-V or mixed voltage rails.

Codecs Part Context

This part belongs to the TLC320AD50/52 family of single-supply analog interface circuits from Texas Instruments. It shares architectural similarities with the TLC320AD50C but differs in its capacity to support only one slave device compared to the three supported by the AD50 variant. Both utilize the same sigma-delta technology for audio conversion.

Codecs Replacement Considerations

TLC320AD50CPT serves as a functional alternative within the same family, offering support for up to three slave devices instead of one. Verify frame-sync timing differences between the AD50 and AD52 variants when substituting.
