TLC320AC02CPM

Codecs Overview

The Texas Instruments TLC320AC02CPM is a single-supply analog interface circuit (AIC) integrating a 14-bit ADC and DAC. It operates on a single 5-V power supply with typical power dissipation of 100 mW. The device features programmable filter bandwidths up to 10.8 kHz and supports synchronous sampling. It provides a signal-to-distortion ratio of 70 dB typical. The component utilizes a 28-pin PQFP package.

Codecs Feature Summary

• Integrates band-pass switched-capacitor antialiasing input filter, 14-bit ADC, 14-bit DAC, and low-pass output-reconstruction filter with (sin x)/x compensation.
• Supports stand-alone, master-slave, and linear-codec operating modes for flexible digital signal processor interfacing.
• Includes differential or single-ended analog outputs with programmable gains and a monitor output with selectable gain settings.

Codecs Applications

• Modems
• Speech processing systems
• Analog interfaces for DSPs
• Industrial process control
• Acoustical-signal processing

Codecs Procurement Notes

Verify the specific suffix 'CPM' against the official datasheet to confirm the package type and temperature range. Ensure the ordering information matches the exact part number required for the design. Confirm availability through authorized distributors as this component may be discontinued or subject to lifecycle changes.

Codecs Selection Notes

Select this component when a single-chip solution for audio-band processing is required. It is suitable for applications needing integrated filtering and conversion without external discrete components. Consider the master-slave capability if multiple channels are needed in a system.

Codecs Part Context

The TLC320AC02 is functionally equivalent to the TLC320AC01 but differs in electrical specifications. It belongs to the family of single-supply analog interface circuits designed for audio applications. The device simplifies system design by combining analog front-end processing with digital serial communication capabilities.

Codecs Replacement Considerations

The TLC320AC01 is functionally equivalent but has different electrical specifications. Verify compatibility before substitution. No other direct replacements are confirmed in the provided documentation.

Codecs FAQ

What are the three basic modes of operation?

The three modes are stand-alone analog-interface mode, master-slave mode, and linear-codec mode.

How is the frame synchronization handled in slave mode?

In slave mode, the frame synchronization signals are externally generated, and the device receives them from the master.

What is the purpose of the EOC terminal?

The End-of-Conversion (EOC) output goes high at the start of the ADC conversion period and low when conversion is complete.
