3 Description
The INA181-Q1, INA2181-Q1, and INA4181-Q1
(INAx181-Q1) current sense amplifiers are designed
for cost-optimized applications. These devices are
part of a family of bidirectional, current-sense
amplifiers (also called current-shunt monitors) that
sense voltage drops across current-sense resistors
at common-mode voltages from –0.2V to 26V,
independent of the supply voltage. The INAx181-Q1
family integrates a matched resistor gain network in
four, fixed-gain device options: 20V/V, 50V/V, 100V/V,
or 200V/V. This matched gain resistor network
minimizes gain error and reduces the temperature
drift.
These devices operate from a single 2.7-V to 5.5-V
power supply. The single-channel INA181-Q1 draws
a maximum supply current of 260μA; whereas, the
dual-channel INA2181-Q1 draws a maximum supply
current of 500μA, and the quad-channel INA4181-Q1
draws a maximum supply current of 900μA.
The INA181-Q1 is available in both the 6-pin, SOT-23
and SC70 packages. The INA2181-Q1 is available
in a 10-pin, VSSOP package. The INA4181-Q1 is
available in a 20-pin, TSSOP package. All device
options are specified over the extended operating
temperature range of –40°C to 125°C.
