TLV320AIC21CPFB Description

Short technical summary and product information.

The Texas Instruments TLV320AIC21CPFB is a highly integrated, programmable 16-bit dual-channel CODEC designed for low-power applications. It features stereo 16-bit oversampling Sigma-Delta converters for both analog-to-digital (ADC) and digital-to-analog (DAC) conversion.

 

Key electrical specifications include selectable input and output gain, programmable sampling rates up to 104 kSPS (with filters bypassed), and typical SNR values of 84 dB for the ADC and 92 dB for the DAC. The device supports analog supply voltages from 2.7V to 3.6V and digital core power from 1.65V to 1.95V.

 

This CODEC is fully compatible with common DSP families and microcontrollers, offering a glueless 4-wire interface. It supports various operating modes, including continuous data transfer and turbo mode for faster data transfer. The device is housed in a 48-TQFP package and is designed for surface mounting.

 

Applications for the TLV320AIC21CPFB include voice-band interfaces, wireless accessories, hands-free car kits, and VoIP systems. Its integrated analog functions and programmable features make it suitable for a wide range of audio processing tasks.
