Phoenix, Ariz. – The CAT5140 digital potentiometer from ON Semiconductor is a 256-tap, single-channel linear-taper digitally programmable potentiometer (DPP). The new device is a low-noise, reliable ...

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 ...

Digital potentiometers (pots) offer advantages for audio volume (gain) control applications and can replace bulky mechanical pots, especially in handheld portable devices such as MP3 players, PDAs, ...

Digital potentiometers enable systems designers to program resistive values in the circuit during initial calibration or even later on, during normal operation of the circuit. This ability permits the ...
