Part Number: TIDA-00328 Other Parts Discussed in Thread: INA300 , INA225 , INA225EVM Hello,
I am checking the TIDA-00328 50MA to 20A current sensing solution, it could be useful for my application.
Please, what is the role of R1 (0ohm) and R2 (0ohm…
Part Number: INA300 Other Parts Discussed in Thread: INA225 , TIDA-00328 Hi, Let me talk about the small current sensing. Customers are considering using INA 300 with a threshold of about 40 mA. I want concerns and advice about sensing design with small…
Hello Hari,
The maximum full-scale linear output ratio I calculated was a quick calculation of Vout_max/Vout_min = 5V/0.05V = 100. This is actually not techincally accurate, but just for comparison. Any voltage output amplifier will have a linear region…
Hello Tomoaki,
What is your desired output range? Are you seeking a 0-5V output signal to be fed into an ADC? With such a large current range, I would recommend taking a look at TIDA-00328 , which uses the INA225 along with the comparator of the INA300…
Hello Nikos,
1. The datasheet was written over 40 years ago...I don't know if it was actually built...the original authors are long gone. But it is a common circuit.
2. Assumptions were probably a large current .The LM324 is not considered a "precision…
