| 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...
| 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...
| This circuit may be used to replace the single current limiting resistor often found in dirt cheap battery chargers. The alternative shown h...
| 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...
| 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...
| A rectangular-wave pulse generator with an extremely long period can be built using only two components: a National Semiconductor LM3710 sup...
| Processor based systems usually require a voltage supervisor chip to produce a clean reset pulse to the processor whenever a ‘brown-out’ con...
| 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...
| When it is necessary to send a digital signal between two electrically isolated circuits you would normally choose an optoisolator or some f...
