S ignal conditioning modules T EM xxxx CN Series 201 08.31 A/1 Page of M ORNSUN Guangzhou Science Technology Co., Ltd. reserves the copyright and right of final interpretation Typical application circuit one: Positive and negative power supply current signal detection scheme The signal conditioning module TEMxxxxCN series, in the dual power supply conditions (VCC, VEE), can be used to detect any direction s current values As shown in the Fig. if the current detection resistor series to the current loop, then the loop current will generate mV level voltage signal in the resistance, the signal conditioning module s complete signal amplification, and feedback to the back-end instrument. The resistance values, to be measured current range, and the signal conditioning modules should be match ed such as: needs to detect the current, signal conditioning module s select 100mV model, so the detecting resistors should be 20m Ω and the resistance value can be realized by controlling the PCB line length. Sin+ Sin- Pin+ GND/Sout- Sout+ VCC COM Sin VEE Current sense resistor Load equipment Input voltage Typical application circuit two: Single power supply and an absolute value circuit scheme Based on the application scheme one, if only provide a single power supply VCC for the signal conditioning modules, then,by using the above figure's peripheral circuit, we can Calculate the absolute value for the output signal. As shown in the figure, the Sout+ pin is positive voltage signal, the first stage operational amplifier and a diode are not working, second stage operational amplifier is working, the output voltage equal to Sout+ pin s voltage. The Sout+ pin's signal is positive voltage, the first stage operational amplifier will reverse the signal, the second stage operational amplifier output voltage equal to the voltage on the Sout+ pin, but in the opposite direction. Therefore, it realizes the absolute value operation for the Sout+ pin voltage signal. In the figure, the values of two output resistance should consider the power consumption and their divider for second stage operational amplifier's input impedance, here to recommend 10K Ω Sin+ Sin- Pin+ GND/Sout- Sout+ VCC Current sense resistor Load equipment Input voltage Typical application circuit three: The detection scheme based on the resistance bridge pressure As shown in the figure, the pressure strain resistance is connect ed in a bridge structure, the change in pressure makes the corresponding change of resistance value, and in the bridge circuit, the change of the resistance will cause the voltage change between the Sin+ and Sin- pins. This voltage is typically mV level, but signal conditioning module s can make the signal from mV level amplify to V level, for the back end uses. sin R R R R R R Vref V To match it, let R1=R2=R3=R, is the pressure strain resistance, Vsin is the voltage between Sin+ and Sin- pins. The above equation can be simplified to sin R R R Vref V Sin+ Sin- Pin+ GND/Sout- Sout+ Vref
