The INA280 is a current sense amplifier that can
measure voltage drops across shunt resistors over a
wide common-mode range from 2.7 V to 120 V. It is in
a highly space-efficient SC-70 package with a PCB
footprint of only 2.0 mm × 2.1 mm. The current
measurement accuracy is achieved thanks to the
combination of an ultra-low offset voltage of ±150 μV
(maximum), a small gain error of ±0.5% (maximum),
and a high DC CMRR of 140 dB (typical). The INA280
is not only designed for DC current measurement, but
also for high-speed applications (like fast overcurrent
protection, for example) with a high bandwidth of 1.1
MHz (at gain of 20 V/V) and an 85-dB AC CMRR (at
50 kHz).
The INA280 operates from a single 2.7-V to 20-V
supply and draws a 370-μA supply current (typical).
The INA280 available with five gain options: 20 V/V,
50 V/V, 100 V/V, 200 V/V, and 500 V/V. The low offset
and drift of the INA280 enables accurate current
sensing over the extended operating temperature
range of −40°C to +125°C. INA280A1IDCKR
