Setup Example for Configuring the AD7616 for High Dynamic Range Applications
by Aidan Frost
Rev. 0 | Page 1 of 9
INTRODUCTION
The AD7616 is a dual, simultaneous sampling, 16-channel,
16-bit successive approximation register (SAR), analog-to-
digital converter (ADC). The AD7616 is ideally suited to pro-
tection and measurement applications in the energy distribution
market. The AD7616 contains a host of features designed with
protection and measurement applications in mind, such as an
integrated programmable gain amplifier (PGA) with a low drift,
1 MΩ input impedance, highly flexible programmable sequencer,
and the ability to perform oversampling up to 128×. This appli-
cation note provides a detailed description of how to configure
the AD7616 in one of its many modes of operation to achieve
an increased dynamic range of more than 100 dB. This application
note is intended as a quick start reference for the user to integrate
the AD7616 into the application.
