LC2MOS 20-Bit A/D Converter

GENERAL DESCRIPTION The AD7703 is a 20-bit ADC that uses a S-D conversion technique. The analog input is continuously sampled by an analog modulator whose mean output duty cycle is proportional to the input signal. The modulator output is processed by an on-chip digital filter with a six-pole Gau

20位Σ-Δ ADC

AD7703是一款采用Σ-Δ型转换技术的20位ADC。通过一个模拟调制器对模拟输入进行连续采样，模拟调制器的平均输出占空比与输入信号成比例关系。调制器输出由含六极点高斯响应的片内数字滤波器进行处理，该滤波器使用16位二进制字以最高4kHz的字速率更新输出数据寄存器。采样速率、滤波器转折频率和输出字速率由主时钟输入设置，主时钟输入可由外部提供，或由晶体控制片内时钟振荡器提供。\n\n 该ADC固有的线性度出色，端点精度由零电平和满量程的自动校准来保证，自动校准可以随时启动。自动校准方案也可以被扩展用来校准系统零点偏置和输入通道中的增益误差。\n\n 输出数据可通过一个灵活串行 • 单片16位ADC\n\n• 0.0015%线性度误差\n\n• 片内自动校准电路\n\n• 可编程低通滤波器\n- 0.1 Hz 到 10 Hz转折频率;
