Product Overview: INA213BIDCKR from Texas Instruments
The INA213BIDCKR is a high-precision, voltage-output, current-shunt monitor from Texas Instruments (TI), designed to measure the drop across shunts at common-mode voltages from -0.3V to +26V, independent of the supply voltage. This particular model comes in an SC-70/SOT-323 package, which is known for its compact footprint and is suitable for space-constrained applications.
With an impressive quiescent current of just 50 µA, the INA213BIDCKR is optimized for power-sensitive systems. This low power consumption makes it an ideal choice for battery-operated equipment. The device boasts a wide input common-mode voltage range, ensuring versatility in various use cases, from industrial to automotive and consumer electronics.
One of the standout features of the INA213BIDCKR is its accuracy. It offers an error of less than 1% over the entire temperature range, which is critical for precise current measurement applications. The device is capable of sensing drops across shunts at full-scale voltages of 100 mV to 500 mV, providing flexibility in the selection of shunt resistors.
The INA213BIDCKR also features a gain of 50 V/V, which allows for small-signal differential voltage amplification. This is particularly useful when dealing with low voltage drops across shunt resistors, as it ensures that the output remains within a readable range for analog-to-digital converters or other monitoring circuits.
This current-shunt monitor is designed with ease of use in mind. It has a simple two-terminal input that connects directly across the shunt resistor. Additionally, the output is directly connected to a measurement or control system without the need for complex circuitry. TI's INA213BIDCKR is also RoHS compliant, adhering to environmental standards and regulations.
Overall, the INA213BIDCKR from Texas Instruments is a robust and reliable solution for current measurement in a wide array of applications. Its high accuracy, low power consumption, and compact form factor make it an excellent choice for designers looking to incorporate current sensing capabilities into their systems with minimal impact on the overall size and power budget.
