AD7723 16位、1.2 MSPS、CMOS Σ-Δ 型ADC

AD7723: 16位、1.2 MSPS、CMOS Σ-Δ 型ADC

AD7723是一款完全16位、Σ-Δ型ADC,采用+5 V电源供电。模拟输入由模拟调制器连续采样,因而无需外部采样保持电路。调制器输出由有限脉冲响应（FIR）数字滤波器处理。在大多数情况下,通过片内滤波并配合高的过采样比,可将外部抗混叠要求降至一阶。数字滤波器频率响应可编程为低通或带通。

The AD7723 is a complete 16-bit, sigma-delta ADC. The part operates from a +5 V supply. The analog input is continuously sampled, eliminating the need for an external sample-and-hold. The modulator output is processed by a finite impulse response (FIR) digital filter. The on-chip filtering combined with a high over-sampling-ratio reduces the external anti-alias requirements to first order in most cases. The digital filter frequency response can be programmed to be either low-pass or band-pass.
