INA301A3IDGKR

The Texas Instruments INA301A3IDGKR is a versatile current sense amplifier designed for high-precision measurements. It features a wide common-mode voltage range from 0 V to 36 V, making it suitable for various applications. The device integrates both a high-accuracy amplifier and a high-speed overcurrent comparator with a programmable alert threshold.

Key electrical specifications include a maximum input offset voltage of 35 µV, a gain error of 0.1% maximum, and a bandwidth of up to 550 kHz. The amplifier offers selectable voltage gains of 20 V/V, 50 V/V, or 100 V/V. The integrated comparator has a total alert response time of 1 µs and an open-drain output with latching mode capability.

This current monitor is available in an 8-VSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C. The INA301A3IDGKR is designed for applications requiring accurate current monitoring and overcurrent detection, such as power management systems, battery chargers, and motor control.

Features such as high precision, low offset voltage, and fast response time make the INA301A3IDGKR a reliable choice for demanding designs. The device's ability to handle high common-mode voltages simplifies system design and reduces component count.
