INA196AIDBVR

The INA196AIDBVR is a high-precision, low-power, monolithic current shunt monitor from Texas Instruments. It is designed to measure both current and power in a wide range of applications, including battery-powered systems, industrial control, and renewable energy systems.

Description:

The INA196AIDBVR is a precision current shunt monitor that integrates a low-side current shunt amplifier with a precision 24-bit ΔΣ ADC. It is available in a 10-lead MSOP package and operates from a single 2.7V to 5.5V supply. The device features a programmable gain amplifier (PGA) that can be configured to measure shunt currents from 10μA to 10A.

Features:

1. Wide input voltage range: 2.7V to 5.5V
2. Programmable gain amplifier (PGA) with 16 gain settings
3. 24-bit ΔΣ ADC for high resolution and accuracy
4. Low power consumption: 190μA in normal mode and 2.2μA in shutdown mode
5. Wide shunt current range: 10μA to 10A
6. I2C and SPI communication interfaces
7. Alert pin for overcurrent detection
8. Small 10-lead MSOP package

Applications:

1. Battery-powered systems: Monitoring battery current and calculating remaining battery life.
2. Industrial control: Measuring motor currents and protecting against overloads.
3. Renewable energy systems: Monitoring the performance of solar panels and wind turbines.
4. Power supplies: Measuring output current and protecting against overcurrent conditions.
5. Energy harvesting systems: Monitoring the energy flow in energy harvesting applications.
6. Medical equipment: Measuring and monitoring currents in medical devices.

In summary, the INA196AIDBVR is a versatile and accurate current shunt monitor that can be used in a wide range of applications requiring precise current and power measurements.
