INA220BIDGSR Digital Current and Power Monitor High/Low-Side 10mA 10-VSSOP
The INA220BIDGSR is a high-precision, bi-directional digital current and power monitor with an I2C-compatible interface from Texas Instruments. This digital monitor integrates a low-drift, programmable gain amplifier, a high-resolution ADC, and a precision shunt voltage reference to accurately measure current, bus voltage, and calculate power. Operating from a single 3V to 5.5V supply, it monitors a shunt resistor across a common-mode bus voltage ranging from 0V to 26V, making it ideal for system monitoring, battery management, and power optimization in a wide array of applications from industrial controls to portable electronics. Its digital output provides robust noise immunity and simplifies interfacing with microcontrollers.
