INA226 Current and Voltage Monotors module 0-36V

ใช้วัดแรงดันไฟฟ้า DC 0 - 36V วัดกระแสไฟฟ้าได้สูงสุด 800mA ใช้แรงดันไฟฟ้าในการทำงาน 2.7V ถึง 5.5V ใช้กระแสไฟฟ้า 420 uA เชื่อมต่อกับไมโครคอนโทรลเลอร์ผ่าน I2C ความละเอียดการวัด 16 บิต Features: • Single-chip solution with I2C interface supports current, voltage, and power measurements, simplifying board design and addressing layout constraints without the need for an external multiplexer or ADC; • Industry's highest accuracy with 10 uV Maximum offset voltage and 0.1% maximum gain error for higher accuracy at low currents and smaller shunt resistors for reduced I*R losses; • Independently programmable conversion time and sample averaging techniques Not only simplifies the customization of speed requirements for each system, but also reduces software and memory requirements; • 420 uA maximum quiescent current and 2 uA maximum shutdown current for efficient operation, even with INA226 integrated ADC and power multiplexer Power consumption is also 3.5% lower than discrete solutions from competing products; • 140 dB common-mode rejection ratio (CMRR) and 36 V common-mode voltage (CMV) ensure minimal or no change over the entire operating range The varying offset voltages simplify the error analysis.
