TLV320AIC15CDBT

Codecs Overview

The TLV320AIC15CDBT 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 filters are bypassed. It operates within an analog supply voltage range of 2.7 V to 3.6 V and a digital core voltage range of 1.65 V to 1.95 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 programmable gain amplifiers, microphone preamplifiers, handset amplifiers, and headset amplifiers for complete voice signal conditioning.
• Features selectable FIR/IIR filters with bypass options to optimize group delay for active control applications.
• Supports Smart Time Division Multiplexed (SMARTDM) serial port for glueless interface to DSPs and microcontrollers.
• Includes extensive power management capabilities allowing independent software control for turning off specific internal sections.

Codecs Applications

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

Codecs Procurement Notes

Verify the exact ordering suffix against the manufacturer's current documentation to confirm package type and temperature rating. Ensure compatibility with system power supplies and serial interface requirements before finalizing procurement decisions.

Codecs Selection Notes

Select this component for mono voice-band applications requiring low power consumption and high integration. Consider the SMARTDM interface for direct connection to compatible processors. Evaluate thermal performance if operating near the upper temperature limits.

Codecs Part Context

This part belongs to the TLV320AIC1x family of low-power audio codecs. It shares architectural similarities with the TLV320AIC12, AIC13, and AIC14 models, differing primarily in specific output driver configurations and package availability within the same functional series.

Codecs Replacement Considerations

The TLV320AIC15IDBT serves as the industrial temperature grade replacement for this commercial grade part. Other family members like the TLV320AIC12K offer additional speaker driver capabilities but require different pinout considerations.
