Hi Engineers,
Recently I found the chip INA214 and this chip support very well my current shunt applicantion, but I tried to simullate on Tina my circuit but without sucess. My simulation appeared a saturation.
My circuit is a power supply with 3V peak sinuidal symetric power supply. My shunt resistor is 100R/0.1% and my load is a variable resistence between 0 and 300R. working with bidirectional
This current sensor will be send analog signal to ADC of Tiva129x, then I need adapt my signals to 3V Peak. This mode I need a Shunt amplifier with gain 50 to price Vpeak 1.5 + 1.5DC offeset.
Then I consider Rload = 0R then my current will be 30mA, and My ADC will read 3V and
I attached in design of circuit on TiNa. Someone can help me solve the problem. Thanks for you attention and best regards. 0181.correntesense.TSC
