3 Description

The INA241x is an ultra-precise, bidirectional current

sense amplifier than can measure voltage drops

across shunt resistors over a wide common-mode

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 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 ensures minimal signal

disturbance at the output due to the common-mode

voltage transitions at the input.

The INA241x operates from a single 2.7 V to 20 V

supply, drawing 2.5 mA of supply current. The

INA241x 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 is specified over operating temperature

range of ?40°C to +125°C and is offered in a spacesaving

8-pin SOT-23 and 8-pin VSSOP package.
