TIINA238AQDGSRQ1
Overview
The INA238AQDGSRQ1 is an automotive-qualified (AEC-Q100), high-side or low-side power monitor with a 16-bit delta-sigma ADC and an I2C-compatible interface. It measures shunt voltage, bus voltage, and temperature while providing integrated power, current, and energy calculations. With a wide common-mode range of -0.3V to 85V, it is designed for precise current sensing in high-voltage vehicle systems.
Why Choose This Part
It offers exceptional accuracy with a 0.1 percent gain error and a high-resolution 16-bit ADC to minimize measurement uncertainty. The device reduces host MCU overhead by performing onboard calculations for power and current while maintaining low power consumption with a 640 uA typical operating current.
Applications
Key Specifications
Getting Started
Interface with the device via the I2C bus using a standard micro-controller; the programmable conversion times and averaging help filter noise in switching environments. For rapid prototyping, look for the INA238EVM evaluation module which provides a hardware platform for testing various shunt resistor configurations.
