TLV320AIC13CDBT

Codecs Overview

The TLV320AIC13CDBT is a low-power, highly integrated mono voice codec manufactured by Texas Instruments. It features one 16-bit oversampling sigma-delta analog-to-digital converter (ADC) and one 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 analog supply voltage of 2.7 V to 3.6 V. The ADC achieves an 84 dB signal-to-noise ratio (SNR), while the DAC reaches 92 dB SNR. Power consumption is 11.2 mW at 3.3 V in standard operation. It utilizes SMARTDM serial interface and includes programmable gain amplifiers, microphone preamplifiers, and selectable FIR/IIR filters.

Codecs Feature Summary

• Integrates mono 16-bit oversampling sigma-delta ADC and DAC channels for high-resolution voice-band signal conversion.
• Features smart time division multiplexed (SMARTDM) serial port for glue-free interface to DSPs and microcontrollers.
• Includes built-in analog functions such as microphone preamplifier, handset/headset amplifiers, and programmable gain control.
• Supports extensive power management with independent software control for ADC, DAC, and operational amplifiers.

Codecs Applications

• Wireless accessories
• Hands-free car kits
• VOIP devices

Codecs Procurement Notes

Verify the specific ordering suffix 'CDBT' corresponds to the commercial temperature range (0°C to 70°C) and TSSOP-30 package. Confirm the datasheet revision status, as this component family has undergone multiple revisions. Ensure compatibility with the required host processor interface protocols before finalizing procurement specifications.

Codecs Selection Notes

Select the TLV320AIC13CDBT for applications requiring a single-channel voice codec with low power consumption. Choose this variant over industrial versions if the operating environment remains within the commercial temperature range. Verify that the system clock requirements align with the master clock input constraints and that the available serial interface modes meet the host controller's capabilities.

Codecs Part Context

This component belongs to the TLV320AIC1x family of low-power audio codecs from Texas Instruments. The family includes variants like the AIC12, AIC14, and AIC15, which share similar core architectures but differ in specific analog output drivers and package options. The 'C' designator indicates the commercial temperature grade, distinguishing it from the 'I' grade industrial version.
