Other Parts Discussed in Thread: TL071H, TL071, LM358B, LM321LV
Originally, I wanted to amplify the voltage of about 0.1V~1.0V using TL071HIDR. So when I looked at the data sheet (6.3) of the TL071H, it said that the minimum value of "input voltage range" was (V-)4. I thought that this means that even if I connect the (V-) of the TL071 to 0V (GND) and input 0.1V~1.0V, it will not be amplified correctly. So I thought it would be a good idea to prepare a negative voltage for TL071HIDR. It seems that LMC7600 will reverse the power supply and output it, so I thought I would put 5V in and output -5V. At that time, I would like to know whether the current supplied by the LMC7600 can drive the TL071HIDR. Figure 4 shows that the output voltage increases from -5V depending on the load current. Considering that the input voltage is around 0V, I would like you to keep it below -4V. In addition, I want to drive TL071HIDR4 and LTC19661 (155 μA typical, 170 μA maximum). I also want to know how many amps are needed to drive the TL071H.
