TLC320AD56CPT

Codecs Overview

The Texas Instruments TLC320AD56CPT is a single-channel audio codec featuring sigma-delta analog interface technology. It provides 16-bit resolution with a dynamic range of 85 to 87 dB for both ADC and DAC channels. The device operates on a single 5V supply, supporting digital voltages from 4.5V to 5.5V and analog supplies from 4.75V to 5.5V. It utilizes a serial interface for data transfer and is housed in a 28-pin FN package. The component supports sampling rates up to 22.05 kHz and functions within an operating temperature range of 0°C to 70°C.

Codecs Feature Summary

• Integrates sigma-delta modulation for high-fidelity audio signal conversion
• Supports serial digital interface for simplified system connectivity
• Operates on a single 5V power supply to reduce system complexity

Codecs Applications

• Voice recognition systems
• Telephony equipment
• Audio recording devices
• Speech synthesis applications

Codecs Procurement Notes

Verify the specific package variant, as the CPT suffix denotes a 48-LQFP package while other variants like CFN use a 28-pin FN package. Confirm that the required dynamic range specifications align with the 85-87 dB performance metrics documented for this series. Ensure compatibility with the 0°C to 70°C industrial temperature range if deployed in standard commercial environments. Check current availability status as distribution channels may vary for discontinued or legacy components.

Codecs Selection Notes

Select this component when a single-channel solution with integrated sigma-delta modulation is required for voice-band audio processing. It is suitable for designs needing a single 5V supply rail and serial interface compatibility. Consider the package size constraints, as the CPT version uses a 48-LQFP footprint unlike the smaller 28-pin alternatives. Evaluate the 85-87 dB dynamic range against application noise floor requirements before finalizing the design.

Codecs Part Context

This part belongs to the TLC320AD56 series of single-channel codecs from Texas Instruments. The series includes various package options such as the 28-pin FN and 48-LQFP configurations. These components are designed for applications requiring efficient analog-to-digital and digital-to-analog conversion using sigma-delta techniques. The family targets cost-sensitive audio interfaces where moderate resolution and dynamic range are sufficient.

Codecs Replacement Considerations

Public confirmed substitute part numbers include TLC320AD50CPTR and TLC320AD56CFN. Verify pinout compatibility and package dimensions when switching between the 48-LQFP and 28-pin FN variants. Ensure that the replacement maintains the required 5V operation and serial interface timing characteristics.
