SZA1010 Description
SZA1010 The SZA1010 or Digital Servo Driver 3 (DSD-3) consists of 1-bit class-D power drivers, which are specially designed for digital servo applications. Three such amplifiers are integrated in one chip, to drive the focus and radial actuators and the sledge motor of a pact disc optical system. The main benefits of using this principle are its higher efficiency grade pared to conventional analog power amplifiers,...
