TLV320AIC15IDBT

Codecs Overview

The TLV320AIC15IDBT is a low-power, highly integrated mono voice 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 a maximum sampling rate of 26 kSPS with on-chip filters or up to 104 kSPS when bypassed. It operates within a digital core voltage range of 1.65 V to 1.95 V and an analog supply range of 2.7 V to 3.6 V. The component utilizes the SMARTDM serial interface for DSP communication and includes an I2C/S2C host port for configuration. It is characterized for industrial operation from -40°C to +85°C and housed in a TSSOP-30 package.

Codecs Feature Summary

• Integrates programmable gain amplifiers, microphone preamplifiers, and handset/headset drivers for complete voice signal conditioning.
• Supports cascading up to 16 devices to a single serial port via automatic cascade detection.
• Includes selectable FIR/IIR digital filters and analog antialiasing filters for optimized voice band processing.

Codecs Applications

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

Codecs Procurement Notes

Verify the specific suffix IDBT indicates the industrial temperature grade (-40°C to +85°C) and TSSOP-30 package. Confirm the revision status as production data may be subject to obsolescence notices. Ensure compatibility with required power supply rails before ordering.

Codecs Selection Notes

Select this model for mono voice applications requiring low power consumption and high integration. The IDBT variant is suitable for industrial environments. Consider the AIC12K if speaker driving capability is needed, or the AIC14K for alternative packaging options within the same functional family.

Codecs Part Context

This component belongs to the TLV320AIC1x series of low-cost, low-power audio codecs. The series shares common architecture including sigma-delta conversion and SMARTDM interfaces. The AIC15 specifically lacks the integrated speaker driver found in the AIC12K variant but retains full voice band processing capabilities.

Codecs Replacement Considerations

Public confirmed substitutes include TLV320AIC15IDBTR (reel version) and TLV320AIC14IDBT (similar performance, different package/variant). Verify pinout and register compatibility before substitution.
