DESCRIPTION

The L6243/D is a Bipolar IC developed for use in Hard Disk Head Actuator positioning applications. The Power Op-Amp Output Bridge, Differential Amplifier, and Error Amplifier, are controlled by TTL/CMOS, input compatible, Digital Logic, and an Analog Current Control Voltage. A simple RC compensation network, tied to the output of the Error Amp, will configure the system to work as a Transconductance Amplifier to drive a Voice Coil Motor in LinearMode.
