.. either the UP or DOWN pin remains low after the first volume transition the volume will change again, but this time after 10 cycles. The followed transition occurs at 4 cycles for each volume transition. This is intended to provide the user ...
The core element of any electronic device is the power supply. Any instability or malfunction of the power supply causes the device to malfunction or demonstrate weird behavior. In some sensitive applications, we need a dual voltage-rail power ...
.. modes, one 8-bit high-speed Timer/Counter, Universal Serial Interface, Internal and External Interrupts, a 4-channel, 10-bit ADC, a programmable Watchdog Timer with Internal Oscillator, and three software selectable power saving modes. ...
.. protection. F1 is a 500 mA fuse and R1 is the 7D471 varistor to protect the device against high-voltage transients. T1 is a 10 mH common mode choke and C1 is a 100 nF-X2 capacitor to reduce the noise. The circuit shunt resistor should be a ...
.. that adds another buck. But worsetly (??? Ed.), it happens that the RC PWM application involves rather low, only 5% to 10%, PWM duty cycle numbers. When you combine that with the LTC6992 datasheet’s specification (on page 4) of 3% ...
Self-heated Darlingtion transistor pair linearly senses airflow using just two wires for both power in and signal out. Suppose we take a common TO-92 transistor and heat it to a constant temperature differential above ambient. The power input ...
Front-panel push button controls can conveniently adjust a PCB-mounted internal potentiometer’s resistance. Digital potentiometers in conjunction with MCUs find common use in analog circuits. The processor can adjust the gain of an amplifier, ...
.. circumstances. This type of circuit has been published in a number of forms, often with slow optocouplers that require 5 to 10 mA of LED drive. These circuits may work in a limited set of applications, but they are slow and still produce ...
.. motor current was about 1.2 Amps with a speed of about 1000 RPM. At 1000 RPM, the pulse frequency works out to be 200 Hz. A 10 kHz ramp generating oscillator is used as the timing generator for the PWM circuit. An op amp compares the ramp ...
