- The circuit in Figure 1, using a low-offset amplifier, is a basic ohmmeter circuit common in multimeters, except for the addition of the two diode-connected transistors. A current source supplies a selectable current, I M , to ranging from 100 nA ...04-10-2021
- Many single-supply applications need precision amplifiers that can operate from 5 V or lower. Although many precision, single-supply op amps are currently available for configuring as 2- and 3-amplifier instrumentation amplifiers (IAs), these ...30-09-2021
- The data sheet for the LT3080 linear voltage regulator suggests using printed-circuit-board (PCB) traces for ballast resistors. Although the LT3080’s low offset voltage suits it well for this technique, it can be used for other ballast ...13-07-2021
- The circuit in Figure 1 provides a 20-MHz square wave across a set of highly capacitive ion-deflection plates in an experimental instrument. To get the required deflection, the plate voltage must be 20 to 30 V, much higher voltage than conventional ...09-07-2021
- Digital potentiometers are versatile devices; you can use them in many filtering and waveform-generation applications. This Design Idea describes an oscillator in which setting the resistance of two digital potentiometers independently programs the ...02-06-2021
- Deadband circuits find applications in servo-control systems. A precision current source and a half-wave inverting rectifier form a positive deadband circuit (Figure 1). The REF01 , IC 1 , is a precision 10 V voltage reference. It forms a precision ...01-06-2021
- Some sports enthusiasts want to know altitude changes from an initial elevation. A small, lightweight, portable altimeter is easy to design using modern micromachined pressure transducers. Inverting barometric pressure and compensating for ...11-05-2021
- The circuit in Figure 1 serves as a variable, current-sink load for testing voltage sources. You use digital commands to set the load current of the device under test over a wide range, independently of the device under test's output voltage. ...12-04-2021
- Instrumentation amplifiers serve in a variety of applications that need to extract a weak differential signal from large common-mode noise or interference. However, designers often overlook the potential problem of RF rectification inside the ...04-04-2021
- It is always desirable to use a low-battery indicator that consumes as little power as possible. For a 9 V, 450-mAhr alkaline battery, a 50-µA low-battery indicator can by itself run the battery down in a little more than a year. ...11-03-2021
