The d/a converter includes an amplifier, which delivers an output voltage, and three resistors connected to the amplifier terminals. An array of switches is connected to a resistor bridge and generate a voltage applied to the amplifier input. A current mirror, reproducing the current in the resistor bridge, is connected to a second array of switches. The voltage generated by these switches is applied to the converter resistor. A bias voltage is generated by a third array of switches. |
