AD1877集成電路（IC）的ADC/DAC-特殊用途規(guī)格書PDF中文資料

AD1877屬于集成電路（IC）的ADC/DAC-特殊用途。由亞德諾半導體技術有限公司制造生產的AD1877ADC/DAC - 特殊用途該產品族中的產品可用于模擬和數字表示的信息轉換，適用于特定用例，或集成了通用數據轉換器中不常見的其他功能。例如針對超聲或汽車雷達應用集成了低噪聲放大器和可變增益級的器件、注重音頻和視頻的產品、在段碼式顯示器上集成顯示測量值功能的器件、集成輸入輸出電氣隔離的器件等。

PRODUCT OVERVIEW

The AD1877 is a stereo, 16-bit oversampling ADC based on Sigma Delta (∑?) technology intended primarily for digital audio bandwidth applications requiring a single 5 V power supply. Each single-ended channel consists of a fourth-order one-bit noise shaping modulator and a digital decimation filter. An on chip voltage reference, stable over temperature and time, defines the full-scale range for both channels. Digital output data from both channels are time-multiplexed to a single, flexible serial interface. The AD1877 accepts a 256 × FS or a 384 × FS input clock (FS is the sampling frequency) and operates in both serial port “master” and “slave” modes. In slave mode, all clocks must be externally derived from a common source.
