... Philips Semiconductors Digital Servo Driver 3 (DSD-3) |H| Fig.7 Amplitude transfer. Switches The digital part of the power drivers consists of standard cells. The power switches are specifically designed for CD applications. The most important feature is their on-resistance. In the applications, they have to drive very low-ohmic actuators and/or motors. The switches are ...

... Philips Semiconductors Digital Servo Driver 3 (DSD-3) SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities ...
