Analog Devices Inc. Data Acquisition Signal Chains

Analog Devices Inc. Data Acquisition Signal Chains are signal chain options that provide highly scalable solutions for data acquisition, with trade-offs between power, bandwidth, and noise. These chains are typified by simplified analog front-end design with antialiasing protection. Single-channel signal chains can be utilized in multichannel systems where channel-to-channel isolation is required.
