TLV320AIC20KIPFBR

Codecs Overview

The TLV320AIC20KIPFBR 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 and two digital-to-analog converters. The device supports differential and single-ended analog inputs and outputs, including microphone, handset, headset, line, and speaker interfaces. It operates with a maximum sampling rate of 26 ksps when using internal filters, or up to 104 ksps with filters bypassed. The component utilizes a SMARTDM serial port for DSP interfacing and an I2C/S2C host port for control. Electrical specifications include an ADC signal-to-noise ratio of 84 dB and a DAC SNR of 92 dB over a 13-kHz bandwidth. Power supplies range from 2.7 V to 3.6 V for analog sections and 1.65 V to 1.95 V for the digital core.

Codecs Feature Summary

• Integrates stereo 16-bit oversampling sigma-delta A/D and D/A converters with built-in analog functions such as programmable gain amplifiers and sidetone control.
• Supports flexible serial communication via the SMARTDM interface for glueless connection to DSPs and microcontrollers, alongside an I2C or S2C host port for configuration.
• Includes selectable FIR/IIR digital filters and comprehensive power management modes to optimize energy consumption in portable applications.

Codecs Applications

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

Codecs Procurement Notes

Verify the specific suffix K indicates industrial temperature rating (-40°C to 85°C) compared to commercial variants. Confirm package type is 48-TQFP (7x7 mm). Check RoHS compliance status and moisture sensitivity level prior to ordering. Ensure supply chain sources provide original manufacturer documentation.

Codecs Selection Notes

Select this model for applications requiring industrial temperature operation and high integration. Compare against TLV320AIC20 for commercial grade needs. Consider pin compatibility if replacing older AIC2x series components. Verify voltage domain requirements for both analog and digital supplies match system constraints.

Codecs Part Context

This component belongs to the TLV320AIC2x family of audio CODECs. It shares architectural similarities with the TLV320AIC20, TLV320AIC21, TLV320AIC24, and TLV320AIC25. The 'K' suffix specifically denotes the industrial temperature range variant within this product line.

Codecs Replacement Considerations

TLV320AIC20IPFBR is the commercial temperature equivalent. TLV320AIC24KIPFBR offers similar functionality but with different analog input/output configurations suitable for multi-channel applications.
