The AD7195 is a low noise, complete analog front end for high precision measurement applications. It contains a low noise, 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC). The on-chip low noise gain stage means that signals of small amplitude can be interfaced directly to the ADC. The AD7195 contains ac excitation, which is used to remove dc-induced offsets from bridge More

The AD6659 is a mixed-signal, dual-channel baseband receiver supporting radio topologies requiring two receiver signal paths, such as in main/diversity or direct conversion. This communi-cations systems processor consists of two high performance analog-to-digital converters (ADCs) and noise shaping requantizer (NSR) digital blocks. It is designed to support various commu-nications applications More

AD7401A*是一款二阶Σ-Δ调制器，片上的数字隔离采用ADI公司的iCoupler® 技术，能将模拟输入信号转换为高速1bit数据流。AD7401A采用5V电源供电，差分输入信号范围为±200 mV（满量程±320 mV）。模拟调制器对输入信号连续采样，因而无需外部的采样保持电路。输入信息包含在数据率为10MHz输出流中，通过适当的数字滤波器重构原始信息。串行I/O可采用5V或3V电源供电(V_DD2).

串行接口采用数字式隔离。通过将高速CMOS工艺和单片空芯变压器技术结合在一起，较之传统光耦合器等其他元件来说，片上隔离能提供更加优异和杰出的工作特性。该芯片内置片上基准源。AD7401A采用16引脚SOIC封装，其工作温度范围为-40°C ～ +125°C。
