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.
