[introduction] the circuit that retreat Ou is the peculiar circuit in multistage amplifier, also be the circuit that must install. The action of the circuit that retreat Ou is to eliminate various amplifier mutual the harmful interference between. The circuit that retreat Ou connects standing buy to be between two class amplifier, only so the ability in multistage amplifier has the circuit that retreat Ou.   The circuit that retreat Ou is the peculiar circuit in multistage amplifier, also be…

[introduction] see at ordinary times too much very classical operation amplifier applies atlas, but build the base in double power source, great a long time is awaited, the architect of circuit must use power supply of only power source, but do not know this how to change the circuit of double power source into circuit of only power source again. When designing circuit of only power source need compares circuit of double power source more careful, the architect must understand…

[introduction] thermal resistor is nominal block value is to be below the condition that temperature is 25 C, measure with special apparatus. Below spare condition, resistor of usable also avometer is blocked undertake detecting, but when avometer detects because work electric current is bigger and form fuel factor, the value that often makes be measured and nominal block is worth not conform to.   The character of 1. thermistor reachs action   Thermal resistor is normally by very sensitive to…

[introduction] LT8609, LT8609A, LT8609B and LT8609S are to have 3 V to come 42 V is the synchronism of limits of wide input voltage, odd a type, step-down manostat. Series of this parts of an apparatus needs for those only low EMI, efficient optimize with the application of small size solution, agree with the car of requirement severe exacting, industry, computation and communication application. All manostat in this series all have identical 2 A transient state of successive, 3 A…

[introduction] believe a lot of people to screen inductance and blame screen inductance it is easier and promiscuous. According to magnetism screen function different, produced what screen inductance and blame screen inductance differ two kinds this to make a way, have in screen inductance stick an inductance, also have labour word inductance, same blame screen inductance also is such.     How do we undertake distinguishing quickly to screen inductance and blame screen inductance then? What distinction is there between…
