Overview
The INA193AMDBVREPG4, produced by Texas Instruments, is a high-performance current shunt monitor designed to sense voltage drops across shunts at a wide range of common-mode voltages. This device is particularly suited for applications in defense, aerospace, and medical fields due to its controlled baseline and extended operating temperature range.
The INA193AMDBVREPG4 operates from a single supply voltage of 2.7 V to 18 V and features a bandwidth of up to 500 kHz, making it suitable for use in current control loops. It is available in a space-saving SOT23 package and offers three output voltage scales: 20 V/V, 50 V/V, and 100 V/V.
