Miniature, Ultra - Light Current Mode Analog Servo Amplifier
Ideal for trapezoidal commutation
The Castanet is a series of ultra-light current mode servo amplifiers for
DC brush and trapezoidal brushless motors. Weighing only 0.76 oz (21.5 g), the Castanet can support up
to 3.3 amps continuous current. This high power density servo amplifier can deliver up to 480 W of peak power or 240 W of continuous power.
The servo amplifier offers significant operating features, including excellent output linearity and
zero dead band performance. The Castanet is a PCB mounted device that enables efficient, cost
saving implementation.
