Texas Instruments INA199
The INA199 series of voltage-output, current-shunt monitors (also called current-sense amplifiers) are commonly used for overcurrent protection, precisioncurrent measurement for system optimization, or in closed-loop feedback circuits. This series of devices can sense drops across shunt resistors at commonmode voltages from –0.3 V to 26 V, independent of the supply voltage. The low offset of the zero-drift architecture enables current sensing with maximum drops across the shunt as low as 10-mV full-scale.| Part No. | INA199 |
