3 Description

The INA241x-Q1 is an ultra-precise, bidirectional

current sense amplifier than can measure voltage

drops across shunt resistors over a wide commonmode

range from –5 V to 110 V, independent

of the supply voltage. The high-precision current

measurement is achieved through a combination of

low offset voltage (±10 μV, maximum), small gain

error (±0.01, maximum) and a high DC CMRR

(typical 166 dB). The INA241x-Q1 is designed for

high voltage, bidirectional measurements in switching

systems that see large common-mode voltage

transients at the device's inputs. The enhanced PWM

rejection circuitry inside the INA241x-Q1 ensures

minimal signal disturbance at the output due to the

common-mode voltage transitions at the input.

The INA241x-Q1 operates from a single 2.7 V to

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

INA241x-Q1 is available in five gain options: 10 V/V,

20 V/V, 50 V/V, 100 V/V, and 200 V/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 and is offered

in a space-saving 8-pin SOT-23 and 8-pin VSSOP

package.
