Method and arrangement for multichannel analog/digital conversion

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, characterized in that an order of processing the channel sample detected in the respective first or second channel provision area (31, 35), which channel sample is provided by the analog selection signal (15) in an A/D conversion provision area (31) and then converted by the A/D converter, is calculated and determined individually for each channel sample by a channel controller (4).

An arrangement for multichannel analog/digital (A/D) conversion, wherein the arrangement samples, by means of a respective first and second S/H (Sample & Hold) element, in a first and second channel respectively in a first or second channel provision area a first and second analog signal awaiting conversion and applies the respectively stored sample value thereof as a channel sample to a first and second input of an analog multiplexer for selection, wherein the arrangement then processes the respective channel sample 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, characterized in that an expiry of the multichannel analog/digital conversion calculated in a channel controller (4) or defined by hardware by an expiry controller is valid for the respective entire channel including the detection of the channel sample in the first or second channel provision area (32), (35).

An arrangement for multichannel analog/digital (A/D) conversion, wherein the arrangement samples, by means of a respective first and second S/H (Sample & Hold) element, in a first and second channel respectively in a first or second channel provision area a first and second analog signal awaiting conversion and applies the respectively stored sample value thereof as a channel sample to a first and second input of an analog multiplexer for selection, wherein the arrangement then processes the respective channel sample 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, characterized in that an order of processing the channel sample detected in the respective first or second channel provision area (31, 35), which channel sample is provided by the analog selection signal (15) in an A/D conversion provision area (31) and then converted by the A/D converter, is calculated and determined individually for each channel sample by a channel controller (4).
