2 Overview

The INA2290 device is a voltage-output, high-side dual channel current sense amplifier in a VSSOP (8) package. As shown in Table 2-1, the INA2290 has gains that range from 20 V/V to 500 V/V, depending on the gain option that is selected. The voltage developed across the device inputs is amplified by the corresponding gain of the specific device, and is presented at the output pin. The device can accurately sense voltage drops across shunts at 2.7-V to +120-V common-mode voltages, dependent of supply voltages. The device survives common-mode voltages from –20 V to +122 V. The device operates with supply voltages between 2.7 V and 20 V, and draws a typical of 350 µA per channel at room temperature.
