INA237AIDGSR
Brand: Texas Instruments
The INA237AIDGSR extends TI's digital power-monitor family with a -0.3 V to +85 V common-mode range — well beyond the INA226 — and a faster I²C interface running up to 2.94 MHz. Its integrated 16-bit ADC and programmable ±163.84 mV / ±40.96 mV shunt range make it a versatile monitor for high-voltage bus and battery-pack power measurement.

Analog Features & Applications
- -0.3 V to +85 V common-mode range reaches well beyond the INA226 for high-voltage bus monitoring
- I²C output at up to 2.94 MHz gives faster telemetry updates than the standard-speed INA226
- Programmable ±163.84 mV / ±40.96 mV shunt range adapts to different shunt-resistor values
- Integrated 16-bit ADC digitizes both shunt current and bus voltage without external converters
- -40°C to +125°C extended-temperature rating suits automotive-adjacent and outdoor equipment
- 10-pin VSSOP package keeps board footprint small for space-constrained power-monitoring designs
