TLV320AIC13IDBT

Codecs Overview

The TLV320AIC13IDBT is a low-power, highly integrated mono audio codec manufactured by Texas Instruments. It features a 16-bit oversampling sigma-delta analog-to-digital converter (ADC) and a 16-bit digital-to-analog converter (DAC). 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 an analog supply of 2.7 V to 3.6 V. Key performance metrics include an ADC signal-to-noise ratio of 84 dB and a DAC SNR of 92 dB. Power consumption is 11.2 mW at 3.3 V in standard operation. The component is housed in a TSSOP-30 package.

Codecs Feature Summary

• Integrates programmable gain amplifiers, microphone preamplifiers, handset amplifiers, and headset amplifiers for voice-band applications.
• Features Smart Time Division Multiplexed (SMARTDM) serial port for glueless interface to DSPs and microcontrollers.
• Includes selectable FIR/IIR filters and supports hardware/software power-down modes for optimized energy conservation.
• Provides a flexible two-wire host port configurable as I2C or S2C for register control.

Codecs Applications

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

Codecs Procurement Notes

Verify the specific ordering suffix IDBT corresponds to the industrial temperature range (-40°C to 85°C) and TSSOP-30 package configuration. Confirm that the tape and reel quantity matches project requirements, typically 250 units per reel for this designation. Ensure compatibility with existing PCB footprints and verify moisture sensitivity level handling procedures during assembly.

Codecs Selection Notes

Select this component for mono voice applications requiring low power consumption and high integration. It is suitable for designs utilizing TI DSPs due to the native SMARTDM interface support. Consider the 84 dB ADC and 92 dB DAC SNR for voice clarity requirements. Verify that the 26 ksps maximum sampling rate meets the bandwidth needs of the intended audio application.

Codecs Part Context

This part belongs to the TLV320AIC1x family of low-cost, low-power mono codecs. It shares architectural similarities with the TLV320AIC12, TLV320AIC14, and TLV320AIC15, differing primarily in specific pin configurations and integrated driver capabilities found in the K-series variants. The IDBT suffix denotes the industrial temperature grade and surface-mount packaging.

Codecs Replacement Considerations

The TLV320AIC13IDBTG4 is a lead-free version of this component. Other family members like the TLV320AIC12IDBT may serve as alternatives if pinout and feature sets align with the design requirements.
