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.
