TLV320AIC15IDBTG4

Codecs Overview

The TLV320AIC15IDBTG4 is a low-power, highly integrated mono voice band codec manufactured by Texas Instruments. It features a 16-bit oversampling sigma-delta analog-to-digital converter and a matching digital-to-analog converter. The device supports programmable sampling rates up to 26 ksps with on-chip filters or 104 ksps when bypassed. It operates with a 2.7 V to 3.6 V analog supply and a 1.65 V to 1.95 V digital core supply. Key specifications include an 84 dB typical SNR for the ADC and 92 dB for the DAC. The component utilizes the SMARTDM serial interface for DSP communication and includes an I2C/S2C host port for configuration.

Codecs Feature Summary

• Integrates mono 16-bit sigma-delta ADC and DAC with programmable gain amplifiers and built-in microphone, handset, and headset amplifiers.
• Features selectable FIR/IIR anti-aliasing and reconstruction filters alongside a bypass option for flexible signal processing.
• Supports glueless connection to TI DSPs via the SMARTDM synchronous serial port and allows cascading of up to 16 devices.
• Includes comprehensive power management with independent software control for ADC, DAC, and amplifier sections.

Codecs Applications

• Wireless accessories
• Hands-free car kits
• VOIP systems
• Cable modems

Codecs Procurement Notes

Verify the specific ordering suffix 'IDBTG4' against the manufacturer's current documentation to confirm package type, temperature range, and RoHS compliance status. Ensure the design accommodates the required 3.3 V analog supply voltage and 1.8 V digital core voltage. Confirm that the TSSOP-30 package dimensions align with the PCB footprint requirements.

Codecs Selection Notes

Select this component for applications requiring a single-channel voice codec with low power consumption. Verify compatibility with the target DSP using the SMARTDM interface. Consider the AIC12K variant if an integrated speaker driver is needed, as the AIC15 lacks this feature. Ensure the system clock supports the maximum 100 MHz master clock requirement.

Codecs Part Context

This part belongs to the TLV320AIC1x family of low-power mono codecs from Texas Instruments. The family includes variants like the AIC12, AIC13, and AIC14, which share similar core architectures but differ in features such as output drivers or package options. The ID suffix indicates industrial temperature range operation, while the DBT suffix denotes the TSSOP package.

Codecs Replacement Considerations

The TLV320AIC15IDBT is a non-RoHS version of the same functional device. For lead-free requirements, the TLV320AIC15IDBTG4 is the direct equivalent. Other family members like the TLV320AIC13 may serve as alternatives if pinout and feature sets are compatible.
