1-11-2004 | Just add an A/D converter and a few discrete LEDs to this temperature sensor chip and you get a simple thermometer. This application builds...

1-07-2004 | Fans are usually monitored by measuring their operating currents. If the current lies within a certain range, it is assumed that the fan is...

1-07-2004 | Standard three-legged voltage regulator chips like the LM317 can cope with an input voltage of up to about 30 V, a few high-voltage types ca...

1-07-2004 | Modern digital systems work with a supply voltage of +3.3 V, and sometimes they also need an additional, lower supply voltage, such as 1.8 V...

1-07-2004 | This circuit may be used to replace the single current limiting resistor often found in dirt cheap battery chargers. The alternative shown h...

1-07-2004 | The National Semiconductor LMV225 is a linear RF power meter IC in an SMD package. It can be used over the frequency range of 450 MHz to 200...

1-07-2004 | It is often necessary in complex designs to provide a sequence of reset pulses to different parts of a circuit to ensure the whole design fu...

1-07-2004 | A rectangular-wave pulse generator with an extremely long period can be built using only two components: a National Semiconductor LM3710 sup...

1-07-2004 | Processor based systems usually require a voltage supervisor chip to produce a clean reset pulse to the processor whenever a ‘brown-out’ con...

1-07-2004 | The gain of an operational amplifier is usually set using two external resistors. If you wish to have adjustable gain, you can use a digital...
