AD1555是一款完整的Σ-Δ调制器,并集成有可编程增益放大器,主要用于低频、高动态范围的测量应用。该器件输出与模拟输入成比例的1密度位流。当配合数字滤波器/抽取器AD1556使用时,可实现带宽为1+ kHz的业界最高性能ADC。
它采用连续时间模拟调制器输入架构,无需外部抗混叠滤波器。可编程增益前端可简化系统设计,扩展动态范围,并缩小系统板面积。低工作功率和待机模式使AD1555成为电池供电远程数据采集系统的理想之选。
The AD1555 is a complete sigma-delta modulator, combined with a programmable gain amplifier, intended for low frequency, high dynamic range measurement applications. The AD1555 outputs a ones-density bit stream proportional to the analog input. When used in conjunction with the AD1556 digital filter/decimator, the industry's highest performance ADC at a bandwidth of 1+ kHz is realized.
The continuous-time analog modulator input architecture avoids the need for an external anti-alias filter. The programmable gain front end simplifies system design, extends the dynamic range, and reduces system board area. Low operating power and standby modes makes the AD1555 ideal for remote battery-powered data acquisition systems.
