1-07-2001 | The EDE1144 Keypad Encoder IC from E•Lab Digital Engineering (www.elabinc.com) is designed to interface a matrix-type 4 row × 4 column (16-k...

1-07-2001 | When a lithium-ion battery is discharged below the minimum recommended cell voltage its life expectancy is dramatically reduced. The circuit...

1-07-2001 | In the December issue we’ll describe a fancy Li-Ion charger based on a specially designed IC and boasting many bells and whistles. However,...

1-07-2001 | ICs for measuring currents usually employ external sense resistors with values of a few tens of milliohms. Not only are such resistors diffi...

1-07-2001 | It frequently happens that you have an application in which you want to measure the temperature of a circuit or the outside world. This can...

1-07-2001 | If you say that the term ‘Opentherm’ is unfamiliar to you, then this will not surprise us the least. Opentherm is a protocol, which can cont...

1-07-2001 | Nowadays, there is a whole series of switching regulator ICs that work according to the step-up principle and thus convert the input voltage...

1-07-2001 | Some applications notes are real evergreens. This one originally dates from 1979(!) but has lost nothing of its relevance and is always very...

1-07-2001 | Recent advancements in circuit integration have drastically reduced the production costs of radio-controlled clocks. These days they are not...
