INA209AIPWR FAQs

1.Q: Are there evaluation tools available for INA209?

A: Yes, Texas Instruments provides the INA209EVM evaluation module for prototyping and testing.

2.Q: What is the default I2C address of the INA209?

A: The default I2C address is 0x40 (7-bit), but it can be adjusted via pin strapping for multi-device systems.

3.Q: Does the INA209 support low-side current sensing?

A: Yes, while optimized for high-side sensing, it can also be used in low-side configurations due to its bidirectional capability.

4.Q: How accurate is the INA209’s current measurement?

A: It offers 1% typical accuracy for current and power measurements with a 100µV input offset voltage.

5.Q: What is the bandwidth of the INA209 current monitor?

A: The bandwidth is 11 kHz, sufficient for most DC/low-frequency current measurements.

6.Q: What package does the INA209 come in?

A: It is available in a 16-pin TSSOP (PW0016A) package with moisture-sensitive properties (MSL rating applies).

7.Q: What is the operating temperature range of INA209?

A: INA209 operates from -40°C to +125°C, suitable for industrial environments.

8.Q: What is the absolute maximum supply voltage for INA209?

A: The absolute maximum supply voltage (VDD) is 6V. Exceeding this may damage the device.

9.Q: What is the typical application circuit for INA209?

A: The typical circuit connects the INA209’s shunt input (VIN+/VIN-) across a current-sense resistor, with VDD to 3.3V/5V and I2C lines (SCL/SDA) to a microcontroller. A 0.1µF decoupling capacitor is recommended near VDD.

10.Q: What are the key features of Texas Instruments INA209 current/power monitor?

A: Key features include high-side measurement, bidirectional current sensing (up to ±26V), I2C interface, programmable gain (1-12x), 1% accuracy, alert function, and operation from 3V to 5.5V supply.
