TLV320AIC24KIPFB

Overview

The TLV320AIC24KIPFB is a low-power, highly integrated, programmable 16-bit, dual-channel audio CODEC manufactured by Texas Instruments. It features two 16-bit oversampling sigma-delta analog-to-digital converters (ADCs) and two 16-bit digital-to-analog converters (DACs). The device supports a maximum sampling rate of 26 kSPS with on-chip IIR/FIR filters enabled, or up to 104 kSPS when the 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 48-pin TQFP package.

Feature Summary

• Integrates stereo 16-bit oversampling sigma-delta A/D and D/A converters for high-resolution signal conversion.
• Includes built-in analog functions such as microphone, handset, and headset amplifiers, along with programmable input and output gain stages.
• Features selectable FIR/IIR digital filters with bypassing capability to optimize power consumption and performance.
• Supports glueless interface to DSPs via SMARTDM serial port and flexible host port using I2C or S2C protocols.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'PFB' corresponds to the 48-TQFP package and industrial temperature range (-40°C to 85°C) as defined in the official datasheet. Confirm that the 'K' designation indicates the industrial grade variant. Ensure compatibility with the required voltage domains before procurement.

Selection Notes

Select this component for applications requiring low-power voice-band processing with integrated analog drivers. The industrial temperature rating makes it suitable for automotive environments. Consider the available sampling rates and filter options when designing for specific latency or bandwidth requirements.

Part Context

This part belongs to the TLV320AIC2x family of audio CODECs from Texas Instruments. The 'K' suffix denotes the industrial temperature grade variant, characterized for operation from -40°C to 85°C. It shares functional similarities with the commercial grade AIC24 but offers extended environmental tolerance.

Replacement Considerations

The TLV320AIC24CPFBR is a commercially graded alternative within the same family. Verify if the commercial temperature range (0°C to 70°C) meets application requirements. Other family members like TLV320AIC20KIPFBR share similar interfaces but may differ in analog driver capabilities.
