INA214AIDCKR Datasheet

Voltage Output, Low- or High-Side Measurement, Bidirectional, Zero-Drift Series, Current-Shunt Monitors


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. Six fixed gains are available: 50 V/V, 75 V/V, 100 V/V, 200 V/V, 500 V/V, or 1000 V/V. The low offset of the zero-drift architecture enables current sensing with maximum drops across the shunt as low as 10-mV full-scale.
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.

• Wide Common-Mode Range: –0.3 V to 26 V
• Offset Voltage: ±35 μV (Maximum, INA210)
   (Enables Shunt Drops of 10-mV Full-Scale)
• Accuracy:
   – Gain Error (Maximum Over Temperature):
      – ±0.5% (Version C)
      – ±1% (Versions A and B)
   – 0.5-µV/°C Offset Drift (Maximum)
   – 10-ppm/°C Gain Drift (Maximum)
• Choice of Gains:
