Digital-to-analog converter with temperature compensation

A digital-to-analog converter with a voltage output comprising means for applying a reference voltage, a resistance and switch network for converting a digital input code into an analog output current, an inverting operational amplifier connected to said network and negatively fed back by a feedback resistance, and a reference current source formed by a reference voltage and a resistance determining the reference current, said reference current source being connected to said resistance and switch network for feeding the network, said reference current source being formed by a bipolar reference current source, and including a bipolar voltage source applied to said bipolar current source, said bipolar current source including a first current reflector having input and output transistors of one conductivity type and a second current reflector having input and output transistors of a conductivity type opposite to said one conductivity type, said current reflector being serially connected to one another, and said output transistors thereof being switchable off.
