Overview
The INA206, INA207, and INA208 family of current-shunt monitors, including the INA206AIDRG4, are designed by Texas Instruments to provide accurate and reliable current sensing in a variety of applications. These devices can sense voltage drops across shunts at common-mode voltages ranging from –16 V to 80 V. The INA206AIDRG4, specifically, operates with a gain of 20 V/V and features a bandwidth of up to 500 kHz. It incorporates dual open-drain comparators with internal 0.6-V references and a 1.2-V reference output on 14-pin versions. These monitors are suitable for use in a wide range of environments due to their extended operating temperature range of –40°C to 125°C and a single supply voltage of 2.7 V to 18 V.
