Patent ID: 7358878

Claim:
A method of multichannel analog/digital (A/D) conversion, in which in a first and second channel respectively in a first or second channel provision area a first and second analog signal awaiting conversion is sampled by a respective first and second S/H (Sample & Hold) element and the respectively stored sample value thereof is applied as a channel sample to a first and second input of an analog multiplexer for selection, wherein the processing of the respective channel sample then takes place in a processing cycle of all channels by said channel sample being selected in the analog multiplexer by a digital selection control signal for the analog/digital conversion and provided as analog selection signal at an output of the analog multiplexer and, after the respective channel provision area, being converted in an analog/digital converter, wherein an order of processing the channel sample detected in the respective first or second channel provision area, which channel sample is provided by the analog selection signal in an A/D conversion provision area and then converted by the A/D converter, is calculated and determined individually for each channel sample by a channel controller, wherein calculations created in the channel controller for an expiry of the multichannel analog/digital conversion are valid exclusively for detecting the channel samples in the first or second channel provision area, wherein the detection of the channel sample present in the first or second channel provision area is respectively triggered by a first and second external detection signal.
