This is a digitally controllable electronic potentiometer. The heart of the circuit is a 16 channel analog multiplexer. Controlled by the BCD value at the inputs, the output pin of the multiplexer ...

What signal conditioning circuit could possibly be easier or more straightforward to design than a dual-channel dc amplifier with a common tracking-gain control? Of course, the obvious way to realize ...

A resistor is characterized by an always constant resistive value. With the same applied voltage, it will always pass the same amount of current. The potentiometer, on the other hand, is an electronic ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...

A new breed of electronically adjustable resistors promises to ease fine-tuning in sensors and other electronic devices. Adjustable resistors have come a long way from mechanical potentiometers set ...

CUI Devices has introduced a line of potentiometers with a rotational life of 10,000 cycles and track resistances from from 1kΩ to 2MΩ. PT (photo left) and PTN (right) potentiometers, as they will be ...

TT Electronics has added three new product families and three series expansions to its variable resistor portfolio. Portfolio additions include one new encoder series and two new single turn ...
