Title: Current switch circuit and d/a converter using the same
Inventor: MORI HARUYA
IPC: H03M1/76
Filed: 2000-04-24
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit-size, power consumption, and the lower limit of the output voltage for a current on-off control switch SW using the output of an IIL logic circuit C. SOLUTION: The output of the IIL logic circuit C is connected to the base of the above mentioned NPN transistor Q1 for ON-OFF control and, when the output of the IIL logic circuit C is OFF, the transistor Q1 is turned ON by a constant current supply F1 and turned off when the above output is ON. Thus, the base of the Q1 is supplied with only 0.9 to 1.1 V of R1's voltage drop VR1+Vbe, thereby making it possible to allow the same to be below the breakdown voltage of an IIL transistor. Thus provided that the current supply F1 is made of a PNP transistors, the circuit SW can be constituted of three transistors and one resistor. This constitution can make small the circuit-size and power consumption of the circuit SW and can decrease the lower limit of the output voltage.
