INA180A4IDBVT Description
The INA180A4IDBVT current sensing amplifier is made for applications that are cost-effective. This device belongs to a group of current-sense amplifiers (also known as current shunt monitors) that detect voltage decreases across current-sense resistors at common-mode voltages between -0.2 V and +26 V, regardless of the supply voltage. A matched resistor gain network is integrated into the INAx180 in four fixed-gain device options: 20 V/V, 50 V/V, 100 V/V, or 200 V/V. This network of matched gain resistors lowers temperature drift and decreases gain error.
A single power source ranging from 2.7 to 5.5 volts can power all of these gadgets. The maximum supply current for the single-channel INA180 is 260 A, while the maximum supply current for the dual-channel INA2180 is 500 μA and the maximum supply current for the quad channel is 900 μA.
There are two distinct pin configurations for the 5-pin, SOT-23 package that houses the INA180A4IDBVT. The 8-pin, VSSOP, and WSON packages for the INA2180 are all available. A 14-pin TSSOP package is available for the INA180A4IDBVT. The expanded operating temperature range for all device options is -40°C to +125°C.
