TLV320AIC24CPFBR

Overview

The TLV320AIC24CPFBR is a low-power, highly integrated, dual-channel audio CODEC featuring two 16-bit oversampling sigma-delta analog-to-digital converters and two digital-to-analog converters. It supports a maximum conversion rate of 26 kSPS with internal filters enabled, or up to 104 kSPS when bypassed. The device operates on separate power supplies: 1.65 V to 1.95 V for the digital core and 2.7 V to 3.6 V for analog sections. It achieves an 84 dB signal-to-noise ratio 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 stereo 16-bit oversampling sigma-delta A/D and D/A converters with programmable gain amplifiers and built-in microphone, handset, and headset amplifiers.
• Features selectable FIR/IIR digital filters with bypassing capability and analog sidetone control for flexible signal processing.
• Supports glueless interface to DSPs via SMARTDM serial port and flexible host configuration through I2C or S2C protocols.
• Includes comprehensive power management with hardware and software-controlled power-down modes for individual blocks.

Applications

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

Procurement Notes

Verify the specific ordering suffix CPFBR against the manufacturer's current Package Option Addendum to confirm the TQFP-48 package and commercial temperature range specifications. Ensure compatibility with system voltage requirements before integration.

Selection Notes

Select this component for applications requiring dual-channel voice-band processing with low power consumption. Verify that the required sampling rates and filter characteristics align with the device's capabilities. Confirm interface compatibility with the target processor's serial ports.

Part Context

This part belongs to the TLV320AIC2x family, which includes variants like the AIC20, AIC21, AIC24, and AIC25. These devices share common architectural features but may differ in specific output drivers or temperature ranges. The AIC24 specifically lacks the built-in speaker driver found in some other family members.

Replacement Considerations

Direct replacements within the same family include TLV320AIC20CPFBR, TLV320AIC21CPFBR, and TLV320AIC25CPFBR. Verify functional differences such as the presence of a speaker driver or specific temperature ratings before substitution.
