@BrianHG, I don't think that there's a need for anything fancier than a pc817 opto-coupler for my circuit. I've measured the voltage levels on the foot-switch inputs on some of my music equipment (synths, guitar efx), they're either 3.3 or 5V. So a pc817+diode or pc817+bridg...
RESET, and TEST pins use the same circuit. The function of this circuit is to clean up the input and ensure that it is synchronized with the clock. The chip's INTR pin is connected to a protection diode to drain a negative voltage to ground. Next, the signal goes through three inverter...
If the transistor on the left has a higher input voltage than the transistor on the right, most of the current will go to the left. But if the transistor on the right has a higher input, most of the current will go to the right. This circuit amplifies the voltage difference: even a...
Once the type of photodiode circuit has been identified by applying a current to it (44) and evaluating a voltage occuring at an input of the detection circuit (45) the photodetection circuit adapts itself to it, e.g. a reverse basing voltage is / isn't applied (48) to the photodiode...
Fig. 7. Transient photocurrent of the ITO/PEIE/HFQx-T:ITIC/Au (1.1 nm PEIE) under different reverse bias and a reference respond of the Si photodiode (Hamamatsu S1226-18BQ). Illumination 1 mW/cm2 from LED (λmax = 629 nm). The devices were biased with voltage in the...
triangle wave. (The op-amp keeps that right side of R1 at ground, so the current that charges the capacitor is proportional to the input voltage. In contrast, in a simple R-C charging circuit, the capacitor charges exponentially; the charging current drops as the capacitor's voltage ...
The photodiode circuit comprises at least a photodiode. Once the type of photodiode circuit has been identified by applying a current to it (44) and evaluating a voltage occuring at an input of the detection circuit (45) the photodetection circuit adapts itself to it, e.g. a reverse ...
control signal comes from the bandgap regulator, which I'll explain below. The output circuit also has a current-sense resistor to measure the output current. This limits the output current to 50 mA in case of a short circuit. A diode clamps the output if the input voltage suddenly drops....
