Improved photoelectric isolator linear circuit

Published:2011/4/29 4:50:00 Author:Nicole | Keyword: photoelectric isolator

Using negative feedback technology can improve the transport linearity of photoelectric isolator device. In figure (a), when D1 is in the feedback path, its current is linear with V1. The shortage of this circuit is not considering the nonlinear relationship between photoelectric isolator device current current transfer ratio and working current. So we should choose and adjust devicecarefully. In figure (b), increasing secondary feedback can improve the linearity. The circuit gain is 1, the frequency is 0~30kHz, the dynamic range is -8~+8V, the nonlinear distortion(it is ±8V)is lower than 0.5%, the noise is lower than 1mV, the common-mode voltage is higher than 250V.   (View)

The brightness adjustment circuit diagram using coutesy switch

Published:2011/5/3 21:02:00 Author:Ecco | Keyword: brightness , coutesy switch

The brightness adjustment circuit diagram using coutesy switch(LX1970 visible light sensor) is shown as the chart. The circuit has the following characteristics: First, it uses a CMOS gate to control the LX1970 power, only when the gate outputs high level, LX1970 gets power, LX1970 is a micro-power device, so the power voltage can be provided by gate circuit; Second, the SRC end is connected a blocking diode in series (VD), when LX1970 power cuts off, VD stops, it can play a role of isolation, so that light signals can not be added to the LX1970, and it can play a protective role; Third, + 3.3V DC voltage signal and the PWM signal can be equivalent to the two logic or gate input signals, therefore, changing the DC voltage can also adjust the brightness. VD could choose 1N4148 high-speed switching silicon diode.   (View)
