INA303-Q1 - Texas Instruments

INA303-Q1 High-Precision Current Sense Amplifier

The INA302-Q1 and INA303-Q1 (INA30x-Q1) devices feature a high common-mode, bidirectional, currentsensing amplifier and two high-speed comparators to detect out-of-range current conditions. The INA302Q1 comparators are configured to detect and respond to overcurrent conditions. The INA303Q1 comparators are configured to respond to both overcurrent and under.
