MITSUBISHI M51660L SERVO MOTOR CONTROL FOR RADIO CONTROL DESCRIPTION The M51660L is a semiconductor integrated circuit for use in servo motor control in radio control applications. Housed in a 14-pin molded plastic zig-zag inline package (ZIP), the M51660L contributes to the miniaturization of the set. The built-in voltage regulating circuit, and the differential comparator used in the comparator circuit provide the M51660L with extremely stable power supply voltage fluctuation characteristics and temperature change characteristics.
