Abstract

A device for analogue-to-digital conversion comprises an analogue-to-digital converter, input of which is connected to input bus, a clock input- to SCL bus, output - to output bus, a control unit and a read-only memory, a control unit, output bus. In the device it is added a buffer register with inputs connected to outputs of analogue –to-digital device, output – with first address inputs of the read-only memory, a digital differentiator having inputs connected with outputs of the analogue –to-converter, outputs – with second address inputs of the read-only memory. The control unit includes a binary counter, a read-only memory and an adder; complementing input of the binary counter is connected with SCL bus, outputs – with address inputs of the read-only memory of the control unit, its outputs – with seconds inputs of the digital adder of the control unit, first inputs of which are connected with outputs of analogue-to-digital converter. Outputs of the digital adder of the control unit are connected with inputs of the read-only memory, first inputs of the digital adder are connected with outputs of the buffer register, second inputs are connected with outputs of the read-only memory, output of the digital adder – with output bus.
