ABSTRACT:
A recording-head substrate including a recording element, a driving circuit for driving the recording element, a temperature-detecting element for measuring the temperature of the recording-head substrate by outputting at least one of a maximum output voltage and a minimum output voltage, a first detection circuit for detecting the maximum output voltage from the temperature-detecting element, a second detection circuit for detecting the minimum output voltage from the temperature-detecting element, and first and second output terminals coupled to the first and second detection circuits for outputting the maximum and minimum output voltages respectively.
