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, cell phones, mobile Internet devices, or stereo AM/FM radios. This document describes the types of ...
As it is based on the potentiometer principle, this class produces very high accuracy. The arrows in the block diagram ofFigure 11.7show the signal-flow path for one version; the resistors are selected in sequence so that, with a constant current supply, the test voltage is created within th...
The alarm signal from pin 16 of IC1, is hooked up with a potentiometer P1(Volume) and further integrated with pin 3 of IC2 (LM386) which forms the amplifier stage for driving a loudspeaker during alarm activations. The P1 is included in order to provide a fine tuning option for the al...
