The INA190A3IDCKR is a bi-directional, ultra-precise current sense amplifier manufactured by Texas Instruments. It features picoamp input bias (IB) and enable (ENA) and is designed to sense current in range of -40 to 125 V. The device is rated for a maximum voltage of 40 Volts and includes a 6-SC70 package. It is ideal for low noise, high-precision current sensing applications, such as portable medical equipment, robotics, and automotive systems. The device features integrated EMI filtering, input offset voltage which is low across temperature ranges, low-noise input amplifier, and output amplifier with low impedance drive capability enabling better protection from load faults. Its low input bias current makes it suitable for sensing low levels of current and high common-mode rejection ratio (CMRR) along with continuous short-circuit protection provides added safety for power systems.
