Field Device Having an Analog Output

A field device having an analog output and a digital/analog converter for generating an analog output signal at the analog output, comprising:

• a device for splitting a digital value into a digital coarse portion and a digital fine portion;
• a first circuit having a first pulse width modulator settable as a function of the digital coarse portion and configured to connect to a reference voltage, and a first low-pass stage connected downstream of the first pulse width modulator for generating a first analog signal having a level above the level of the analog output signal of the analog output;
• a second circuit having a second pulse width modulator settable as a function of the digital coarse portion and configured to connect to the reference voltage, and a second low-pass stage connected downstream of the second pulse width modulator for generating a second analog signal having a level below the level of the analog output signal of the analog output;
• and
• a third circuit having a third pulse width modulator settable as a function of the digital fine portion and configured to receive the first analog signal and the second analog signal, an upper level of an output signal of the third pulse width modulator corresponding to the first analog signal and a lower level of the output signal of the third pulse width modulator corresponding to the second analog signal, and having a third low-pass stage for generating the analog output signal connected downstream of the third pulse width modulator.
