TLV320AIC24IPFBR

Overview

The TLV320AIC24IPFBR is a low-power, highly integrated, dual-channel audio CODEC featuring two 16-bit oversampling sigma-delta ADCs and two DACs. It supports a maximum sampling rate of 26 kSPS with on-chip IIR/FIR filters or 104 kSPS when bypassed. The device operates with analog supplies from 2.7 V to 3.6 V and digital core voltage from 1.65 V to 1.95 V. It achieves an SNR of 84 dB for the ADC and 92 dB for the DAC over a 13-kHz bandwidth. The component utilizes SMARTDM serial and I2C/S2C host interfaces.

Feature Summary

• Integrates programmable gain amplifiers, microphone bias, and multiple output drivers including speaker, handset, headset, and line outputs.
• Supports flexible clocking via internal PLL allowing master clock to serve as DSP master clock.
• Includes selectable FIR/IIR filters with bypass capability and analog/digital sidetone control.

Applications

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

Procurement Notes

Verify the specific suffix IPFBR against the manufacturer's current package option addendum to confirm the TQFP-48 package and commercial temperature range specifications. Ensure compatibility with system power supply rails before integration.

Selection Notes

Select this model for applications requiring dual-channel voice-band processing with minimal external components. Consider the AIC24K variant if industrial temperature range operation is required instead of the commercial grade specified for this part number.

Part Context

This component belongs to the TLV320AIC2x family of low-power audio CODECs. It shares architectural similarities with the AIC20, AIC21, AIC25, AIC20K, and AIC24K devices, differing primarily in specific analog interface configurations and temperature ratings.

Replacement Considerations

The TLV320AIC24KFBR serves as a direct replacement offering the same functionality but characterized for the industrial temperature range (-40°C to 85°C) rather than the commercial range (0°C to 70°C).

FAQ

What is the maximum sampling frequency supported by the TLV320AIC24IPFBR?

The device supports a maximum sampling rate of 26 kSPS when using the on-chip IIR/FIR filters, and up to 104 kSPS when the filters are bypassed.

How does the device handle serial communication with DSPs?

It implements the SMARTDM serial port, which is a synchronous 4-wire serial port in TDM format designed for glue-free interfacing with TI DSPs and microcontrollers.

Can the TLV320AIC24IPFBR drive a speaker directly?

No, the TLV320AIC24 does not include a built-in speaker driver; this feature is exclusive to the AIC20/21/20K variants within the family.
