This EVM supports the following features:
The AMC1035 device is a precision, delta-sigma (ΔΣ) modulator that operates from a single 3.0-V to 5.5-V supply and with an externally generated clock signal in the range of 9 MHz to 21 MHz. The differential ±1-V input structure of the device is optimized for use in a noisy environment, as usually found in industrial applications.
Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with the AMC1035EVM.
