TLV320A24KIPFBRG4

Codecs Overview

The TLV320A24KIPFBRG4 is a low-power, highly integrated, programmable 16-bit, dual-channel audio CODEC from Texas Instruments. It features stereo 16-bit oversampling sigma-delta A/D and D/A converters with selectable FIR/IIR filters. The device supports sampling rates up to 26 Ksps with filters active or 104 Ksps when bypassed. It operates on separate analog (2.7 V to 3.6 V) and digital (1.65 V to 1.95 V) supplies. Key specifications include an ADC SNR of 84 dB and DAC SNR of 92 dB over a 13-kHz bandwidth. It integrates microphone, handset, headset amplifiers, and an 8-ohm speaker driver.

Codecs Feature Summary

• Integrates stereo 16-bit oversampling sigma-delta analog-to-digital and digital-to-analog converters for high-resolution signal processing.
• Includes built-in analog functions such as programmable input/output gain amplifiers, microphone bias, and selectable FIR/IIR digital filters.
• Features a fully compatible SMARTDM serial port interface allowing glueless connection to DSPs and microcontrollers with automatic cascade detection.
• Provides extensive power management capabilities with hardware and software-controlled power-down modes for individual sections.

Codecs Applications

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

Codecs Procurement Notes

Verify the component authenticity by checking the marking code against the official datasheet. Confirm the package type matches the 48-TQFP specification. Ensure the temperature grade corresponds to industrial operation requirements if applicable. Cross-reference the ordering suffix to confirm RoHS compliance and specific variant details before finalizing procurement.

Codecs Selection Notes

Select this component for voice-band applications requiring low power consumption and high integration. Consider the available analog inputs and outputs, including dedicated drivers for speakers and headsets. Evaluate the need for programmable gain and digital filtering options. Ensure the host processor supports the SMARTDM or I2C/S2C control interfaces required for configuration.

Codecs Part Context

This part belongs to the TLV320AIC2x family of audio CODECs, which includes variants like the TLV320AIC20, AIC21, AIC24, and AIC25. The 'K' designation typically indicates industrial temperature range characterization. The 'G4' suffix denotes lead-free packaging compliant with RoHS standards. These devices are designed for portable applications due to their efficient power management and single-supply operation capabilities.

Codecs Replacement Considerations

Direct replacements within the same family include the TLV320AIC24IPFB and TLV320AIC20KIPFB. Verify pin compatibility and electrical specifications, particularly supply voltage ranges and thermal performance. Check for any differences in filter characteristics or amplifier drive capabilities that might impact system design.
