DC meter protection amplification circuit made by LM10 and others
The picture 1 is a DC meter protection amplification circuit and is made up of LM10 and others. It is a kind of DC meter protection amplification circuit which needs to work in the temperature of 15 to 55 centigrade. The sensitivity of full scale is lOmV/l0nA. RP2 is used to set to zero. And the based voltage of setting zero is decided by the based voltage in the LM10 and does not affect by the voltage of power supply. RP1 is used to set bias current and VD1 and VD2 are the protecting diodes of LM10. The power supply of this circuit is 1.5 V and the current sinking is about 0.5mA.
