TLC32044是美国德州仪器公司生产的音频接口组件。它是单片CMOS组件,是个完善的A/D,D/A输入/输出系统。它将带通开关电容抗混叠输入滤波器、14位分辨率A/D转换器、4种与微处理器兼容的串行口工作方式、14位分辨率D/A转换器、低通开关电容输出再组合滤波器等部件集成在一个组件里。能提供主时钟输入频率的多种组合和转换/采样速率信号。 用途十分广泛,典型应用包括语音加密、语音识别/存储系统、语音合成、modem(7.2、8、9.6、14.4和1902kHz采样率)、DSP(数字信号处理器)模拟接口、工业过程控制、生物仪器、频谱分析、数据采集和仪器录音等。本文阐述内部定时结构,字的位模式通信协议、应用等6部分内容。
TLC32044 is Texas Instruments audio interface components. It is a monolithic CMOS component and is a complete A / D, D / A input / output system. It will band-pass switched capacitor antialiasing input filter, 14-bit resolution A / D converter, four kinds of microprocessor-compatible serial port work, 14-bit resolution D / A converter, low-pass switch Capacitor output recombination filter and other components integrated in a component. Can provide a variety of combinations of master clock input frequency and conversion / sampling rate signal. Typical applications include voice encryption, speech recognition / storage systems, speech synthesis, modems (7.2,8,9.6,14.4 and 1902kHz sampling rates), DSP (digital signal processor) analog interfaces, industrial process control, biological instrumentation , Spectrum analysis, data acquisition and instrument recording. This article describes the internal timing structure, word bit pattern communication protocol, application 6 parts.
