Title:
VOLTAGE DIVISION CIRCUIT
Document Type and Number:
Japanese Patent JP2567154
Kind Code:
B2
Abstract:
PURPOSE: To attain miniaturization and to reduce the cost by obtaining output voltages divided optionally with high resolution.
CONSTITUTION: n-Sets of resistors R1, R2,...Rn arranged side by side are connected in series, a ground potential Vss is impressed to each one terminal of the n-sets of the resistors R1,R2,...Rn connected in series and a power supply potential VDD is impressed to the other terminal. Each connecting point of the n-sets of the resistors R1,R2,...Rn is connected to a ground line wired on the n-sets of the resistors point of the n-sets of the resistors R1,R2,...Rn is connected to an output line via prescribed switches SW1', SW2,... respectively. Thus, an output voltage VOUT divided optionally is obtained and high resolution, miniaturization and low cost are attained.
