TLV320AIC14CDBT

Codecs Overview

The TLV320AIC14CDBT 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 filters are bypassed. It operates with a digital core supply voltage range of 1.65 V to 1.95 V and an analog supply voltage range of 2.7 V to 3.6 V. The component is housed in a TSSOP-30 package and is characterized for commercial operation from 0°C to 70°C.

Codecs Feature Summary

• Integrates a mono 16-bit ADC and DAC utilizing oversampling sigma-delta technology for high-resolution signal conversion.
• Includes programmable input and output gain control via a programmable gain amplifier (PGA) and built-in microphone, handset, and headset amplifiers.
• Features selectable FIR/IIR digital filters with a bypass option to optimize power consumption and latency.
• Supports Smart Time Division Multiplexed (SMARTDM) serial interface for glueless connection to DSPs and microcontrollers.

Codecs Applications

• Wireless accessories
• Hands-free car kits
• Voice over IP (VOIP) systems

Codecs Procurement Notes

Verify the specific temperature grade suffix 'C' corresponds to the commercial operating range of 0°C to 70°C rather than the industrial range. Confirm the 'DBT' suffix indicates the TSSOP-30 package type. Ensure the source document explicitly lists this exact part number as active production data to avoid obsolete stock issues.

Codecs Selection Notes

Select this component for voice-band applications requiring a single-channel audio path with minimal external components. It is suitable for designs where power conservation is critical, offering independent software control for turning off unused sections like the ADC, DAC, and filters. Ensure the host processor supports the SMARTDM or I2C/S2C interfaces for configuration.

Codecs Part Context

This device belongs to the TLV320AIC1x family of low-power mono codecs. It shares architectural similarities with the TLV320AIC12, AIC13, AIC14, and AIC15 models, differing primarily in specific pin configurations and integrated driver capabilities depending on the sub-model variant.

Codecs Replacement Considerations

TLV320AIC14IDBT serves as the industrial temperature grade equivalent within the same package.
