The INA187 is a precise, bidirectional current sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range from –2V to 42V, independent of the supply voltage. The high-precision current measurement is achieved through a combination of low offset voltage (±150µV, maximum), small gain error (±0.25%, maximum) and a high DC CMRR (typical 120dB). The INA187 is not only designed for bidirectional DC current measurements, but also for high-speed applications (such as transient detection and fast overcurrent protection) with a high signal bandwidth of 650kHz and fast settling time.
The INA187 operates from a single 2.7V to 12V supply, drawing 650µA of supply current. The INA187 is available in three gain options: 20V/V, 50V/V, 100V/V. Multiple gain options allow for optimization between available shunt resistor values and wide output dynamic range requirements.
The INA187 is specified over operating temperature range of −40°C to +125°C and is offered in a 6-pin SOT-23 package.
