Product Overview: Texas Instruments INA212BIDCKR

The INA212BIDCKR is a precision, low-power, voltage-output, current-shunt monitor from Texas Instruments (TI), designed to measure the voltage across shunts at common-mode voltages from -0.3V to 26V, independent of the supply voltage. This versatile component is housed in a small, SC-70 package, making it an excellent choice for space-constrained applications.

With a wide input common-mode voltage range, high accuracy, and low quiescent current, the INA212BIDCKR is particularly well-suited for portable and battery-powered systems where power efficiency and space are critical considerations. It is capable of providing bidirectional current sensing by measuring the differential voltage across a current-sense resistor and converting it into a proportional output voltage.

Key Features

• Wide Common-Mode Range: The device operates over a wide common-mode voltage range from -0.3V to 26V, which is particularly useful for tracking battery levels and sensing in systems with varying ground potentials.
• High Accuracy: The INA212BIDCKR offers a high accuracy current measurement capability, which is crucial for precise monitoring and control in power management systems.
• Low Quiescent Current: With a low quiescent current, the device helps in maintaining overall power efficiency, an essential feature for battery-operated devices.
• Gain Options: The INA212BIDCKR comes with a fixed gain of 200 V/V, providing a straightforward implementation without the need for external gain-setting components.
• Small Package: The SC-70 package is one of the smallest available, making it ideal for portable electronics where space is at a premium.
