Texas Instruments INA199A1DCKR

The Texas Instruments INA199A1DCKR is a high-side current sense amplifier that utilizes a high-precision, low-offset voltage amplifier to measure the current flowing through a shunt resistor. The device features a wide common-mode voltage range of -16V to +80V, allowing for use in a variety of applications, including automotive, industrial, and communication systems. With a quiescent current of only 110µA, the INA199A1DCKR is energy-efficient and helps to extend battery life. The device incorporates an industry-standard gain of 50V/V, which can be adjusted with an external resistor for customized gain values. The output of the device is tied to a comparator that trips when the current reaches a predetermined level, providing a simple and cost-effective current-limiting solution.

The INA199A1DCKR includes a number of additional features, such as a precision bidirectional output, fault detection and indication, and over-temperature protection. This allows for reliable and accurate current sensing, even in harsh industrial environments. The device is available in a small, space-saving SOT-23-5 package, making it easy to incorporate into almost any circuit design. Overall, the Texas Instruments INA199A1DCKR is an ideal solution for applications requiring high-precision current sensing, low power consumption, and robust protection features
