Push–pull outputs are present in TTL and CMOS digital logic circuits and in some types of amplifiers, and are usually realized by a complementary pair of transistors, one dissipating or sinking current from the load to ground or a negative power supply, and the other supplying or sourcing current to the load from a positive power supply.Ī push–pull amplifier is more efficient than a single-ended 'class-A' amplifier. This kind of amplifier can enhance both the load capacity and switching speed.

For this the low range is defined as the ≤ 0.4 V and the high range as ≥ 2.4 V.A Class B push–pull output driver using a pair of complementary PNP and NPN bipolar junction transistors configured as emitter followersĪ push–pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. The TTL output is supplied with either a fixed 5 V voltage or a variable voltage of between 10 and 32 V.

In a transistor-transistor logic (TTL), both the logical status and the amplification are done by transistors, hence the name. “Low” is defined as an output of between 0 V and 3 V and “high” as between VCC and VCC - 3.5 V. High Voltage Transistor Logic functions with a voltage supply in the range 10 and 30 V DC, with 24 V DC being the most usual. The PNP output is an interface based on an output circuit with a PNP transistor. The NPN Open Collector - The NPN Open Collector(NPN) is an interface based on an output circuit with an NPN transistor.Īn open collector is the unconnected collector connection of an NPN transistor, whose emitter is connected to earth and whose collector is connected to the output.

There are plenty of encoder video if you still have any doubts on encoder, please email us directly or contact online service right now.Īt the same time, you could also visit our YOUTUBY page easily. The more pulse per round, the narrower groovy spacing of grating, ore effect to encoder by vibration, when motor speed is low or even stopped, vibration acting on encoder shaft or encoder shell would cause grating vibration, in this way, encoder might show wrong pulse signal. So we have to pay more attention to encoder working place. Vibration acting on an encoder always cause wrong pulse easily.
