美国ADI公司推出的24位∑ -Δ模数转换器AD1555/AD1556内含可编程增益放大器 ,可用于低频、大动态范围的测量 ,并可实现模拟输入线性输出 ,AD1555/AD1556有五种不同的增益设定。将AD1555和AD1556数字滤波器/抽样器结合使用可组成高性能的模数转换器 ,因而可广泛应用于地震数据探测系统和自动测试装置
The AD1555 / AD1556 24-Bit Sigma-Delta Analog-to-Digital Converters from Analog Devices USA contain programmable gain amplifiers for low-frequency, high-dynamic range measurements and analog input linear outputs. The AD1555 / AD1556 have five different Gain setting. The combination of the AD1555 and the AD1556 digital filter / sampler make up a high-performance analog-to-digital converter that can be used in a wide range of seismic data detection systems and automated test equipment
