Voltage Output, High or Low Side Measurement, Bi-Directional Zero-Drift Series - INA199A2

INA199A2 (ACTIVE)

Voltage Output, High or Low Side Measurement, Bi-Directional Zero-Drift Series

Recommended alternative parts

  • INA214  -  Higher Accuracy: 60uV Offset (max) & 0.02 Gain Error
  • INA216A3  -  Low cost option with reduced accuracy and common mode volatge range limnited to 5V maximum

Description

The INA199 series of voltage output current shunt monitors can sense drops across shunts at common-mode voltages from –0.3V to 26V, independent of the supply voltage. Three fixed gains are available: 50V/V, 100V/V, and 200V/V. The low offset of the Zerø-Drift architecture enables current sensing with maximum drops across the shunt as low as 10mV full-scale.

These devices operate from a single +2.7V to +26V power supply, drawing a maximum of 100µA of supply current. All versions are specified from –40°C to +105°C, and offered in both SC70 and thin QFN-10 packages.

Features

  • WIDE COMMON-MODE RANGE: –0.3V to 26V
