The invention provides a current generating circuit with a single configuration, enhanced durability, and low power consumption. A circuit block C1 appropriately selects elemental currents i11 to i14 and i1F in accordance with data (bits) S11 to S14 and S14 and generates a sub-current Iout1. Similarly, a circuit block C2 appropriately selects elemental currents i21 to i24 and i2F in accordance with bits S21 to S24 and S2F and generates a sub-current Iout2. A circuit block C3 appropriately selects elemental currents i31 to i34 and i3F in accordance with bits S31 to S34 and S3F and generates a sub-current Iout3. A circuit block C4 appropriately selects elemental currents i41 to i44 in accordance with bits S41 to S44 and generates a sub-current Iout4. These sub-currents Iout1, Iout2, Iout3, and Iout4 are combined to generate a main current Iout.
