♠ INA199 26-V, Bidirectional, Zero-Drift, Low- or High-Side, Voltage-Output, Current-Shunt Monitor
The INA199 series of voltage-output, current-shunt monitors (also called current-sense amplifiers) 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 shunt resistors at common-mode voltages from –0.3 V to 26 V, independent of the supply voltage. Three fixed gains are available: 50 V/V, 100 V/V, and 200 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 from –40°C to 125°C, and offered in both SC70-6 and thin UQFN-10 packages.
• Wide Common-Mode Range:
–0.3 V to 26 V
• Offset Voltage: ±150 μV (Maximum) (Enables Shunt Drops of 10-mV Full-Scale)
• Accuracy:
– Gain Error (Maximum Over Temperature):
– ±1% (C Version)
– ±1.5% (A and B Versions)
– 0.5-μV/°C Offset Drift (Maximum)
– 10-ppm/°C Gain Drift (Maximum)
• Choice of Gains:
– INA199x1: 50 V/V
– INA199x2: 100 V/V
– INA199x3: 200 V/V
• Quiescent Current: 100 μA (Maximum)
• Packages: 6-Pin SC70, 10-Pin UQFN
