ZN409CE

PRECISION SERVO INTEGRATED CIRCUIT

The ZN409CE is a precision monolithic integrated circuit

designed particularly for pulse-width position servo mecha-

nisms used in all types of control applications. The low

number of components required with the ZN409CE, together

with its low power consumption, make this integrated circuit

ideal for use in model aircraft, boats and cars where space,

weight and battery life are at a premium. The amplifier will

operate over a wide range of repitition rates and pulse widths

and is therefore suitable for the majority of systems. The

ZN409CE can also be used in motor speed control circuits.
