3 Description

The INA241x-Q1 is an ultra-precise, bidirectional

current sense amplifier that can measure voltage

drops across shunt resistors over a wide commonmode

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-Q1 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-Q1 provides minimal

signal disturbance at the output due to the commonmode

voltage transitions at the input.

The INA241x-Q1 operates from a single 2.7V to

20V supply, drawing 2.5mA of supply current. The

INA241x-Q1 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-Q1 is specified over operating

temperature range of ?40°C to 125°C.
