INA194AQDBVRQ1 TI Current Sense Amplifier | SOT-23-5 | 80V, 500kHz

Product Overview

The INA194AQDBVRQ1 is a high-voltage, bidirectional current sense amplifier from Texas Instruments, designed for automotive and industrial applications. It operates from a single 2.7V to 18V supply and can sense common-mode voltages from -16V to 80V, making it ideal for high-side and low-side current sensing. The device features a gain of 50 V/V and a bandwidth of 500 kHz, enabling accurate current measurement in fast-switching systems. Housed in a compact SOT-23-5 package, it is AEC-Q100 qualified for automotive reliability.
