INA199A1DCKT Description

Short technical summary and product information.

The Texas Instruments INA199A1DCKT is an analog current-sense amplifier, also known as a current-shunt monitor. It is designed for applications requiring precise current measurement, such as overcurrent protection and system optimization.

 

This device features a wide common-mode voltage range from -0.3 V to 26 V, making it suitable for various system voltages. It offers a maximum input offset voltage of ±150 µV and a gain error of ±1.5% (for A and B versions), enabling accurate shunt drop measurements. The amplifier supports multiple voltage gains, including 50 V/V, 100 V/V, and 200 V/V, with bandwidths of 14 kHz, 30 kHz, and 80 kHz depending on the configuration.

 

Operating within a temperature range of -40°C to 125°C, the INA199A1DCKT has a low quiescent current of 115 µA maximum. It is available in a compact 6-pin SC-70 package, suitable for surface-mount applications. The bidirectional sensing capability allows for monitoring current in both directions.

 

Key specifications include a high CMRR of 100 dB, low offset voltage drift, and low gain drift, ensuring stable performance over temperature variations. This makes the INA199A1DCKT a reliable choice for current monitoring in demanding environments.
