In the figure is the 9-bit LED LEV displaying drive circuit of LB1409. Figure (a) is the LEV display drive circuit which consists of LV1409, figure (b) is the LEV display drive circuit of application reference voltage. LB1409 is produced by Toyo, Japan, and the local products, such as D1409 and SL1409, are like it, and they can replace it. The LB1409 input pole is indicated with 9 stick-shape red or green LED. Inside the circuit, there is a DC amplifier, whose gains can be changed by external resistors.
