MITSUBISHI <CONTROL / DRIVER IC>
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.
