Digital to analog converter has data word, reference signal inputs, series resistance circuit, tapping for connection via switch to input with first and/or second resistances independently of data word, amplifier with gain setting input

摘要

The device has an input (3) for the data word, a reference input (25) for a reference signal, a series circuit (2) with a first resistance and at least one second resistance, a tapping (6) for connection via a switch to the input with the first and/or second resistance independently of the data word and an amplifier (50) whose input is coupled to the tapping for a gain setting. An independent claim is also included for a method of digital to analog conversion of a data word.
