Description
General part information
INA185-Q1 Series
The INA185-Q1 current sense amplifier is designed for use in cost-sensitive space constrained applications. This device is a bidirectional, current-sense amplifier (also called a current-shunt monitor) that senses the voltage drop across a current-sense resistor at common-mode voltages from –0.2V to 26V, independent of the supply voltage. The INA185-Q1 integrates a matched resistor gain network in four, fixed-gain device options: 20V/V, 50V/V, 100V/V, or 200V/V. This matched gain resistor network minimizes gain error and reduces the temperature drift.
The INA185-Q1 operates from a single 2.7V to 5.5V power supply. The device draws a maximum supply current of 260µA and features high slew rate and bandwidth making this device an excellent choice for many power-supply and motor-control applications.
The INA185-Q1 is available in an industry standard SC70 package. The device is specified over the extended operating temperature range of –40°C to 125°C.
