TLV320AIC20IPFBR

Codecs Overview

The TLV320AIC20IPFBR 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 internal filters enabled, or up to 104 ksps when the IIR/FIR filters are bypassed. It operates with an analog supply voltage range of 2.7 V to 3.6 V and a digital core supply of 1.65 V to 1.95 V. The component achieves typical signal-to-noise ratios of 84 dB for the ADC and 92 dB for the DAC over a 13-kHz bandwidth. It is housed in a 48-pin TQFP package.

Codecs Feature Summary

• Integrates stereo 16-bit oversampling sigma-delta A/D and D/A converters with selectable FIR/IIR digital filters.
• Includes built-in analog functions such as microphone preamplifiers, handset/headset amplifiers, and an 8-ohm speaker driver.
• Features a Smart Time Division Multiplexed (SMARTDM) serial port for glueless interface to DSPs and microcontrollers.
• Supports flexible power management with hardware/software control for independent section shutdown.

Codecs Applications

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

Codecs Procurement Notes

Verify the specific suffix 'IPFBR' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the ordering information matches the latest revision of the SLAS363D document. Confirm availability status directly with authorized distributors as production data may change.

Codecs Selection Notes

Select this component for voice-band applications requiring low power consumption and high integration. Verify that the required sampling rate fits within the 26 ksps limit with filters active or 104 ksps with bypass. Check compatibility with the host processor's SMARTDM or standard serial interface requirements.

Codecs Part Context

This part belongs to the TLV320AIC2x family, which includes variants like the AIC21, AIC24, and AIC25. These devices share similar architectures but differ in specific analog output capabilities, such as the inclusion of a speaker driver in the AIC20/21 series. The 'I' designation indicates industrial temperature range operation.

Codecs Replacement Considerations

Check for TLV320AIC21IPFBR if a speaker driver is not needed. Consider TLV320AIC24IPFBR for different analog input/output configurations. Verify pinout and register compatibility before substituting.
