Abstract
In an analog-to-digital converter circuit and a control device for a gradient amplifier, an analog difference signal is determined from an analog input signal and an analog converter signal. An integrator and an analog-to-digital converter are provided in order to integrate and digitalize the analog difference signal before further evaluation, thereby achieving high precision, resolution and stability with little outlay.
