Circuit configuration for monitoring an output load

摘要

The circuit has a first digital comparator (12) which compares the data words fed to the converter (1) with at least one comparison data word. A second, analogue comparator (5) compares the voltage drop across a resistor (2) in parallel with the output load (4) with at least one reference voltage and drives a flip-flop circuit (8). A comparison circuit (11) controls the size and/or existence of the output load depending on the output signals of the first comparator and the flip-flop. AN Independent claim is also included for applications of the circuit for computer graphics, current digital-analogue converter current balancing and monitoring the bandwidth of the output signal of a current digital-analogue converter.
