INA199B1QDCKRQ1 Description

Short technical summary and product information.

The Texas Instruments INA199B1QDCKRQ1 is an analog output current sense amplifier suitable for automotive applications. It features a wide common-mode voltage range from -0.3V to 26V, enabling shunt drops as low as 10mV full-scale.

 

This device provides a voltage output proportional to the current being measured, with selectable gains of 50 V/V, 100 V/V, or 200 V/V. Key electrical specifications include a maximum input offset voltage of ±150 µV, a typical input offset drift of 0.1 µV/°C, and a maximum gain error of ±1.5%. The bandwidth ranges from 14 kHz to 80 kHz depending on the gain setting.

 

The INA199B1QDCKRQ1 operates within an ambient temperature range of -40°C to 125°C. It is housed in a compact 6-pin SC-70 package, designed for surface mounting. This AEC-Q100 qualified component is functional safety-capable, making it suitable for critical automotive systems.
