SOT-SC70 (DCK)-5-4.2 mm² 2 x 2.1
The INA290-Q1 is an ultra-precise 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 ultra-precise current measurement accuracy is achieved thanks to the combination of an ultra-low offset voltage of ±12 µV (maximum), a small gain error of ±0.1% (maximum), and a high DC CMRR of 160 dB (typical). The INA290-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 INA290-Q1 provides the capability to make ultra- precise current measurements by sensing the voltage drop across a shunt resistor over a wide common- mode range from 2.7 V to 120 V. The INA290-Q1 is available in the SC-70 package minimizing solution size area.
