TLC320AC01CPMR

Codecs Overview

The Texas Instruments TLC320AC01CPMR is a single-supply analog interface circuit (AIC) designed for audio-band signal processing. It integrates a 14-bit ADC and DAC with switched-capacitor filters, providing an analog-to-digital and digital-to-analog input/output interface on a monolithic CMOS chip. The device supports serial port communication with DSPs or microprocessors. Key electrical parameters include a typical power dissipation of 100 mW and a signal-to-distortion ratio of 70 dB. It operates from a single 5-V supply and features programmable filter bandwidths up to 10.8 kHz. The component is characterized for operation within the commercial temperature range of 0°C to 70°C.

Codecs Feature Summary

• Integrates 14-bit resolution ADC and DAC channels with synchronous sampling capabilities.
• Includes band-pass switched-capacitor antialiasing input filter and low-pass output-reconstruction filter with (sin x)/x compensation.
• Supports stand-alone, master-slave, and linear-codec modes for flexible serial-port interfacing.
• Features differential architecture throughout with programmable gains for inputs and outputs.

Codecs Applications

• Modems
• Speech processing systems
• Analog interfaces for digital signal processors (DSPs)
• Industrial process control
• Acoustical-signal processing and spectral analysis

Codecs Procurement Notes

Verify the specific package variant against the datasheet terminal assignments before ordering. Confirm that the operating environment remains within the specified 0°C to 70°C commercial temperature range. Ensure the design accommodates the single 5-V power supply requirement and appropriate bypass capacitors for the VMID terminals. Cross-reference the latest revision SLAS057D for any updates to electrical characteristics or register definitions prior to finalizing procurement.

Codecs Selection Notes

Select this component when a complete analog front end with integrated filtering and conversion is required for audio applications. It is suitable for designs needing programmable filter bandwidths and differential signal handling. Consider the master-slave capability if multiple units must synchronize on a single DSP serial port. Verify that the 14-bit dynamic range meets the system's signal-to-noise requirements and that the serial interface timing aligns with the host processor's specifications.

Codecs Part Context

The TLC320AC01C is part of the Texas Instruments TLC320AC01/02 family of analog interface circuits. It is functionally equivalent to the TLC320AC02, though they differ in specific electrical specifications as detailed in the manufacturer's comparison appendix. This device represents a specialized solution for integrating A/D and D/A conversion with analog filtering in a single CMOS package, targeting cost-sensitive audio and data acquisition markets.

Codecs Replacement Considerations

The TLC320AC02 is functionally equivalent but has different electrical specifications. Verify compatibility by consulting Appendix C of the datasheet for parameter differences. No other direct substitutes are confirmed in the provided documentation.
