Texas Instruments INA214
The INA21x are voltage-output, current-shunt monitors (also called current-sense amplifiers) that are commonly used for overcurrent protection, precision-current measurement for system optimization, or in closed-loop feedback circuits. This series of devices can sense drops across shunts at common-mode 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.- Min Voltage : 4.5V
- Max Voltage : 36V
- Channels : 2
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C

DESCRIPTION
Six fixed gains are available: 50 V/V, 75 V/V, 100 V/V, 200 V/V, 500 V/V, or 1000 V/V. These devices operate from a single 2.7-V to 26-V power supply, drawing a maximum of 100 µA of supply current. All versions are specified over the extended operating temperature range (–40°C to +125°C), and offered in SC70 and UQFN packages.
