Description

The TLV320AIC23BPWR is a high-performance stereo audio codec with highly integrated analog functionality. The analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) within the TLV320AIC23B use multibit sigma-delta technology with integrated oversampling digital interpolation filters. Data-transfer word lengths of 16, 20, 24, and 32 bits, with sample rates from 8 kHz to 96 kHz, are supported. The ADC sigma-delta modulator features third-order multibit architecture with up to 90-dBA signal-to-noise ratio (SNR) at audio sampling rates up to 96 kHz,enabling high-fidelity audio recording in a compact, power-saving design. The DAC sigma-delta modulator features a second-order multibit architecture with up to 100-dBA SNR at audio sampling rates up to 96 kHz, enabling high-quality digital audio-playback capability, while consuming less than 23 mW during playback only. The TLV320AIC23B is the ideal analog input/output (I/O) choice for portable digital audio-player and recorder applications, such as MP3 digital audio players.

Features of the TLV320AIC23BPWR are:(1)High-Performance Stereo Codec;90-dB SNR Multibit Sigma-Delta ADC (A-weighted at 48 kHz);100-dB SNR Multibit Sigma-Delta DAC (A-weighted at 48 kHz);1.42 V 3.6 V Core Digital Supply: Compatible With TI C54x DSP Core Voltages;2.7 V 3.6 V Buffer and Analog Supply: Compatible Both TI C54x DSP Buffer Voltages;8-kHz 96-kHz Sampling-Frequency Support; (2)Software Control Via TI McBSP-Compatible Multiprotocol Serial Port ;2-wire-Compatible and SPI-Compatible Serial-Port Protocols;Glueless Interface to TI McBSPs; (3)Audio-Data Input/Output Via TI McBSP-Compatible Programmable Audio Interface;I2S-Compatible Interface Requiring Only One McBSP for both ADC and DAC;Standard I2S, MSB, or LSB Justified-Data Transfers; (4)16/20/24/32-Bit Word Lengths.
