TLV320AIC24CPFBRG4

Overview

The TLV320AIC24CPFBRG4 is a low-power, highly integrated stereo audio codec featuring two 16-bit sigma-delta ADCs and two 16-bit DACs. It supports sampling rates up to 26 kSPS with on-chip FIR/IIR filters or 104 kSPS when bypassed. The device operates on analog supplies of 2.7 V to 3.6 V and digital core voltage of 1.65 V to 1.95 V. Key performance metrics include an SNR of 84 dB for the ADC and 92 dB for the DAC over a 13-kHz bandwidth. It utilizes a SMARTDM serial interface for DSP connectivity and includes programmable gain amplifiers, microphone bias, and multiple output drivers.

Feature Summary

• Integrates dual-channel 16-bit oversampling sigma-delta converters with selectable FIR or IIR digital filters.
• Features a Smart Time Division Multiplexed (SMARTDM) serial port enabling glueless connection to TI DSPs and microcontrollers.
• Includes built-in analog functions such as microphone preamplifiers, handset/headset amplifiers, and an 8-ohm speaker driver.
• Supports flexible power management with hardware and software-controlled power-down modes for individual sections.

Applications

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

Procurement Notes

Verify the specific suffix 'RG4' against the manufacturer's current documentation to confirm lead times and availability status. Ensure the package type matches the design requirements. Confirm RoHS compliance details directly from the official datasheet before finalizing procurement plans.

Selection Notes

Select this component for applications requiring low-power stereo voice-band conversion with integrated analog front-end capabilities. Verify that the required sampling rate and filter characteristics align with the system's signal processing needs. Ensure the host processor supports the SMARTDM or standard 4-wire serial interface protocols.
