A semiconductor device is adapted for controlling energization of a heating element that performs printing. The semiconductor device includes: a strobe signal input unit receiving a printing strobe signal that causes the heating element to generate heat for printing; a preheating strobe generation circuit generating a preheating strobe signal that causes the heating element to preheat by compressing a waveform of the printing strobe signal in a time axis direction; and an output controller outputting a control signal that controls energization of the heating element based on the printing strobe signal and the preheating strobe signal.

Semiconductor device

An analog-to-digital (AD) conversion circuit includes an analog filter configured to remove a high frequency component of an analog signal to generate a first signal, an AD converter (ADC) configured to AD-convert the first signal to generate a second signal, and a digital filter configured to remove a high frequency component of the second signal to generate a digital signal.
