The INA280-Q1 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-Q1 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-Q1 operates from a single 2.7-V to 20-V supply and draws a 370-µA supply current (typical). The INA280-Q1 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-Q1 enables accurate current sensing over the extended operating temperature range of −40 °C to 125 °C.
