Silicon Genera/(Silicon Pass) Company of the United States produces SG3173 and SG 3172 single
-power operational amplifiers and SG3272 dual-power operational amplifiers . Their technical data are shown
in Table 11-2. They have internal compensation, overcurrent and overtemperature protection. The SG3272 dual operational amplifier can be easily connected to a bridge drive to drive micro
DC motors
in computer peripherals and audio motors for head positioning in 3.5in (88.9mm) hard disk drives .
