A method and apparatus to sense a temperature of a printhead of an inkjet printer includes one or more temperature sensors each included in a respective one of the one or more printheads to measure a temperature of each printhead and output an analog signal corresponding to the measured temperature of the one or more printheads, analog buffers each included in the one or more printheads and connected to the temperature sensor of each printhead to control the output of the analog signals according to predetermined control signals, an analog-to-digital converter to digitalize the analog signals output through the analog buffers, and a driving unit connected to the analog buffers to drive the temperature sensors, wherein the analog buffers determine which temperature sensor is driven by the driving unit based on the predetermined control signals.
