1-12-1999 | The control is a compact design for driving bipolar stepper motors. Driver stages IC2 and IC3 are modern types from ST Microelectronics. B...

1-12-1999 | Until not so long ago, only 8-bit analogue-to-digital converters (ADC) offered an I²C™ interface. Unfortunately, a resolution of 256 sampl...

1-07-1999 | Driven by customer demand, Philips Semiconductor’s AVC Logic family is the fastest logic on the market today and offers ultra low noise an...

1-07-1999 | Systems like the SMBus or I²C™ use a standard resistor to pull up the signal levels to the positive supply rail (normally 5 V). The bus go...

1-07-1999 | If, like many other people, you have ever been annoyed by the noise of, say, the extractor fan in your bathroom, here’s a tip that may q...

1-07-1999 | There are applications in which it is important for the supply voltage to be largely independent of the level of the output current, which...

1-05-1999 | Faultfinding with a multimeter set to measure resistance yields quite a lot of information, but is not without risks. This is because...

1-04-1999 | Designing printed-circuit boards that may be safely connected to the mains supply need not give rise to unnecessary worries. A condition i...
