The INA241x is an ultra-precise, bidirectional current sense amplifier that can measure
voltage drops across shunt resistors over a wide common-mode range from –5V to 110V,
independent of the supply voltage. The high-precision current measurement is achieved
through a combination of low offset voltage (±10µV, maximum), small gain error (±0.01%,
maximum) and a high DC CMRR (typical 166dB). The INA241x is
designed for high voltage, bidirectional measurements in switching systems that see large
common-mode voltage transients at the device inputs. The enhanced PWM rejection circuitry
inside the INA241x provides minimal signal disturbance at the
output due to the common-mode voltage transitions at the input.
The INA241x operates
from a single 2.7V to 20V supply, drawing 2.5mA of supply current. The INA241x is available in five gain options: 10V/V, 20V/V, 50V/V,
100V/V, and 200V/V. Multiple gain options allow for optimization between available shunt
resistor values and wide output dynamic range requirements.
The INA241x is
specified over operating temperature range of −40°C to 125°C.
