Description: TLV320AIC23（以下简称AIC23）是TI推出的一款高性能的立体声音频Codec芯片，内置耳机输出放大器，支持MIC和LINE IN两种输入方式（二选一），且对输入和输出都具有可编程增益调节。AIC23的模数转换（ADCs）和数模转换（DACs）部件高度集成在芯片内部，采用了先进的Sigma－delta过采样技术，可以在8K到96K的频率范围内提供16bit、20bit、24bit和32bit的采样，ADC和DAC的输出信噪比分别可以达到90dB和100dB。与此同时，AIC23还具有很低的能耗，回放模式下功率仅为23mW，省电模式下更是小于15uW。由于具有上述优点，使得AIC23是一款非常理想的音频模拟I/O器件，可以很好的应用在随声听（如CD，MP3……）、录音机等数字音频领域。-TLV320AIC23 (hereinafter referred to as AIC23) is a TI introduced a high-performance stereo audio Codec chip, built-in headphone output amplifier, to support both MIC and LINE IN input (check one), and the input and output are programmable Gain adjustment. AIC23 analog to digital conversion (ADCs) and digital-analog converters (DACs) of highly integrated components inside the chip, using the advanced Oversampling Sigma-delta technology, the frequency in the range of 8K to 96K provide 16bit, 20bit, 24bit and 32bit Sampling, ADC and the DAC s output signal to noise ratio up to 90dB, respectively, and 100dB. At the same time, AIC23 also has very low energy consumption, playback mode, power is only 23mW, power-saving mode is less than 15uW. Because of these advantages, making the AIC23 is a very good analog audio I/O devices, the Walkman can be a good application (such as CD, MP3 ... ...), tape recorders and other digital audio field.
