OQ8844 - Digital Servo Driver DSD-2

OQ8844 Description

INTEGRATED CIRCUITS DATA SHEET OQ8844 Digital Servo Driver (DSD-2) Product specification File under Integrated Circuits, IC01 1995 Nov 27 Philips Se.
OQ8844 The OQ8844 or Digital Servo Driver 2 (DSD2) consists of 1-bit class-D power drivers, which are specially designed for digital servo applicati.

OQ8844 Features

* Servo functions
* 1-bit class-D focus actuator driver (3.3 Ω)
* 1-bit class-D radial actuator driver (3.7 Ω)
* 1-bit class-D sledge motor driver (2.5 Ω). Other features
* Supply voltage 5 V only
* Small package (SOT163-1)
* Higher efficiency, compared

OQ8844 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,
