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.
