TLV320AIC13IDBTR

Codecs Overview

The TLV320AIC13IDBTR is a low-power, highly integrated mono voice codec manufactured by Texas Instruments. It features one 16-bit analog-to-digital converter and one 16-bit digital-to-analog converter utilizing oversampling sigma-delta technology. The device supports a maximum sampling rate of 26 ksps with on-chip filters or up to 104 ksps when bypassed. It operates with a digital core voltage of 1.65 V to 1.95 V, digital I/O voltage of 1.1 V to 3.6 V, and analog supply voltage of 2.7 V to 3.6 V. The component achieves an ADC signal-to-noise ratio of 84 dB and a DAC signal-to-noise ratio of 92 dB. It is housed in a 30-pin TSSOP package.

Codecs Feature Summary

• Integrates programmable gain amplifiers, microphone preamplifiers, handset amplifiers, headset amplifiers, and selectable FIR/IIR filters for comprehensive voice-band processing.
• Supports glueless interface to DSPs via SMARTDM serial port and flexible host port compatible with I2C or S2C protocols.
• Enables independent software control for power management, allowing separate shutdown of the ADC, DAC, operational amplifiers, and filters.

Codecs Applications

• Wireless accessories
• Hands-free car kits
• VOIP systems
• Speech processing

Codecs Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements before integration. Confirm availability status as product lifecycles may change. Cross-reference the datasheet revision date to ensure all electrical characteristics are current.

Codecs Selection Notes

Select this component for applications requiring a single-channel audio conversion solution with low power consumption. Verify that the required sampling rate does not exceed the 26 ksps limit when using internal filters. Ensure the host processor supports the SMARTDM or standard serial interfaces. Check if the industrial temperature range (-40°C to 85°C) meets environmental specifications.

Codecs Part Context

This part belongs to the TLV320AIC1x family of mono voice codecs from Texas Instruments. It shares architectural similarities with the TLV320AIC12, TLV320AIC14, and TLV320AIC15, differing primarily in output driver capabilities and pin configurations. The IDBTR designation indicates the industrial temperature range and tape-and-reel packaging format.

Codecs Replacement Considerations

The TLV320AIC13IDBT is a non-tape-and-reel alternative within the same series. Other family members like the TLV320AIC12 or TLV320AIC14 may serve as substitutes but require verification of pinout and driver specifications.
