Overview of INA199B1DCKR

The INA199B1DCKR is a precision current-sensing amplifier designed for use in applications that require precise current measurement. It operates from a single power supply, typically ranging from 2.7V to 5.5V, making it suitable for a wide range of portable and battery-powered devices. The device features a high common-mode voltage range, allowing it to sense currents even in high-side applications. It offers a gain bandwidth product of 500kHz and a low input offset voltage, ensuring accurate current measurements. With a typical quiescent current of 60 microamps, it minimizes power consumption, making it suitable for low-power applications. The INA199B1DCKR is available in a small SC70 package, enabling compact designs in space-constrained applications. Its integrated features and small form factor make it an ideal choice for precision current sensing in various industrial, automotive, and consumer electronics applications
