The AMP-43520, AMP-43540, and AMP-43740 have been enhanced to incorporate 16 bit PWM resolution. The AMP-43520 and AMP-43540 are 2 and 4 axis 600 Watt sinusoidal amplifiers with a switching frequency of 33 kHz. While, the AMP-43740 is a 4 axis 1200 Watt sinusoidal amplifier with a switching frequency of 20 kHz. Galil has increased the PWM resolution from 12 bit to 16 bit without decreasing the switching frequency. Galil has added the benefits of increasing the resolution on a PWM amplifier without the usual required trade-offs.

Some of the advantages of a high resolution amplifier are enhanced sub-micron positioning, reduced torque ripple, and smoother speed control. Overall, these enhancements will increase the system's performance for many applications.

Any new AMP-43520, AMP-43540, and AMP-43740 will include this upgrade with no change in cost from the previous 12 bit versions.
