Ina219 shunt resistor value
WitrynaA large value resistor will develop a larger differential voltage as the current passes through. The measurement errors will be smaller due to the fixed amplifier offset voltage. However, the larger signal creates a larger power dissipation across the shunt resistor (P = I2R). A smaller shunt resistor develops a smaller drop across the shunt ...
