OQ8844 Product details

Description

OQ8844 The OQ8844 or Digital Servo Driver 2 (DSD2) 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 compact disc optical system.The main benefits of using this principle are its higher efficiency grade compared to conventional analog power amplifiers, its higher integration level, its differential output and the fact that only
