3.1 the amplifier circuit

Published:2011/6/15 3:32:00 Author:Borg | Keyword: amplifier circuit

In figure 4 is the amplifier circuit in the signal adjusting circuit, which is a passive feedback amplifier circuit composed of the computing amplifier, and the amplified times of the output signals can be further trimmed by adjusting the adjustable resistor RW2. The output signal subtracts 0g LEV, which can make the output voltage value of the amplifier be 1/10 of the acceleration, so it is more convenient to indicate the number. By adjusting the resistance of RW2, the 0g LEV can be trimmed, and the signal bias can be modified. In the figure, VSS is a power supply of -5V, VCC is a +5V power supply.   (View)

Double MOS Memory Interface Circuit

Published:2011/5/18 9:43:00 Author:Joyce | Keyword: Double MOS, Memory , Interface

SN75370 is a monolithic integrated read/write interface circuit, which can be used as input/output interface in 4062 and in MOS RAM and TTL circuit of the same type. It can be connected directly with I/O interface of similar MOS RAM like 4062 . When it is written into operation, the drive can provide a complementary high voltage output with a high sensitive read operation.TTL will input with compatible diode clamp of DTL,and output with compatible data of DTL .The output endof data can act as AND connection. And the power supply has a extensive range. As shown in the figure is the interconnection graph of SN75370 and 4062.   (View)

Meeting Timer Circuit

Published:2011/5/18 9:39:00 Author:Joyce | Keyword: Meeting, Timer

As shown in the figure the limited time of this circuit ranges from 5 minutes to 1 hour. PR1, C8 and C9 are the timing components. The sockets for 220V AC power supply,which controls the audio power amplifiers are CZ1 and CZ2. To press AN2, 555 means reset and start .Its feet ③ outputs high level, which will trigger the thyristor to make it breakover.And when CZ1 and CZ2 have voltage，the timing will begin. KD - 153 will produce sounds for a few seconds to indicate the circuit is proper.When the timer stops,feet 5553 will output low level,thus VS will turn off, and no voltage will be on CZ1 and CZ2.After hearing sounds produced by KD - 153 for a few seconds ,the limited time for the meeting is up. The circuit is alsoapplicable for other control circuits which needs timing.   (View)
