Sensor Arus Daya - INA219 Bi-directional Sensor

INA219 at -40C to + 1% can be achieved within the maximum error accuracy 85C temperature range, the maximum offset is 100 uV. The high-precision products combine the advantages of 12-bit resolution, as much as possible to help customers reduce the pressure drop on the shunt resistor, thereby minimizing power loss and power consumption and save board space. The device can be sensed bus voltage range of 0 V to +26 V. INA219 Other important features include: A precision amplifier measures the voltage across the 0.1 ohm, 1% sense resistor. Since the amplifier maximum input difference is 320mV this means it can measure up to 3.2 Amps. With the internal 12 bit ADC, the resolution at 3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is 400mA and the resolution is 0.1mA. Advanced hackers can remove the 0.1 ohm current sense resistor and replace it with their own to change the range (say a 0.01 ohm to measure up 32 Amps with a resolution of 8mA) Programmable calibration register can be read in units of ampere direct current, and read the power in watts. Up to 128 samples can be averaged to achieve filtering in noisy environments. I2C interface has a timeout setting, not only to prevent bus lock, but also provides high-speed mode, to meet the communication requirements of up to 3.4 MHz. All properties INA219 are software programmable to support. A single power supply with the operating voltage of between +3.0 to + 5.5V.
