Abstract
Provided is an analog switch circuit that allows switching between an on-state and an off-state according to a control signal, the analog switch circuit including a main input terminal that receives an input voltage, an output terminal, an upper-side power supply terminal that receives an upper supply voltage, a lower-side power supply terminal that receives a lower supply voltage, a main N-channel MOS transistor and a main P-channel MOS transistor that are disposed in parallel between the main input terminal and the output terminal, and a controller that includes a voltage generating circuit that generates a high-side voltage according to the upper supply voltage and the input voltage and a low-side voltage according to the input voltage and the lower supply voltage. The controller can control a gate and a back gate of each of the main N-channel and P-channel MOS transistors based on the high-side and low-side voltages.
