CMOS 16-Bit, 468.75 kHz, Sigma-Delta ADC

GENERAL DESCRIPTION The AD7721 is a complete low power, 12-/16-bit, sigma-delta ADC. The part operates from a +5 V supply and accepts a differential input of 0 V to 2.5 V or ±1.25 V. The analog input is continuously sampled by an analog modulator at twice the clock frequency eliminating the need

CMOS、12或16位、312.5 kHz/468.75 kHz Σ-Δ 型ADC

AD7721是一款完全低功耗、12位或16位Σ-Δ型ADC，采用+5 V电源供电，接受0 V至2.5 V或±1.25 V差分输入范围。模拟输入由模拟调制器以时钟频率两倍的速度连续采样，因而无需外部采样保持电路。调制器输出由两个串联的有限脉冲响应（FIR）数字滤波器处理。在大多数情况下，通过片内滤波可将外部抗混叠要求降至一阶。当主时钟频率等于15 MHz时，阶跃输入的建立时间为218.4 µs，而滤波器的群延迟为109.2 µs。\n\n AD7721的输入带宽最高可达229.2 kHz，相应的输出字速率为468.75 kHz。该器件也可采用较低的时钟频率工作。由于采样速率、滤波器转折 • 16位Σ-Δ型ADC\n\n• 输出字速率（OWR）：468.75 kHz\n\n• 无失码\n\n• 低通数字滤波器\n\n• 高速串行接口;
