This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.
AD717x Family of ADCs
Analog Devices’ AD717x family of ADCs are designed for high-precision, low-frequency signal measurement.
As signals approach DC, 1/f noise rises sharply, so the AD717x family uses fully chopped input buffers, which shifts the 1/f noise into higher frequencies and minimizes offset error drift. This results in up to 24 noise-free bits of resolution for high precision measurements.
The inputs are connected to a crosspoint multiplexer, which allows any combination of the inputs to form a differential pair or any input to be used as the reference in single-ended operation. This flexibility can effectively reduce cost and design effort by reducing the number of ADCs for a given application.
The AD717x family of ADCs also have a programmable digital filter that provides 85 dB rejection of 50 and 60 Hz line frequencies.
