All diese sind bereits in LTspice mit Symbol hinterlegt. For photodiodes, an equivalent circuit model is an essential analytical tool, because simply inserting a photodiode symbol into a schematic doesn’t tell you much about the signal that will be generated and the ways in which the photodiode will interact with an The symbol for an opto-coupler changes from a schematic representation of a photodiode/phototransistor to a black box with pins in the perifery when I paste it into the schematic page. That means that the bipolar symbols will all use the 4-pin netlist entry, but the 3-pin is also supported. I would like the symbol to remain in the schematic representation since the black box is hard to work with particularly when the symbol is rotated. The "cell" and "signal" parts models only have different schematic symbols, so they can be used as independent voltage sources in the same way as "voltage". The AD8628/AD8629/AD8630 are wide bandwidth auto-zero amplifiers featuring rail-to-rail input and output swing and low noise.
