INA186
Overview
The INA186 is a low-power, voltage-output, currentsense amplifier (also called a current-shunt monitor). This device is commonly used for overcurrent protection, precision current measurement for system optimization, or in closed-loop feedback circuits.
- Wide common-mode voltage range, VCM: -0.2 V to +40 V
- Low input bias currents, IIB: 500 pA (typical) (enables microamp current measurement)
- Low power: - Low supply voltage, VS: 1.7 V to 5.5 V - Low quiescent current, IQ: 48 µA (typical)
- Accuracy: - Common-mode rejection ratio: 120 dB (minimum) - Gain error, EG: ±1% (maximum) - Gain drift: 10 ppm/°C (maximum) - Offset voltage, VOS: ±50 μV (maximum) - Offset drift: 0.5 μV/°C (maximum)
- Bidirectional current sensing capability
- Gain options: - INA186A1: 25 V/V - INA186A2: 50 V/V - INA186A3: 100 V/V - INA186A4: 200 V/V - INA186A5: 500 V/V
