The INA2191 device is a voltage-output, dual channel, bidirectional current sense amplifier in a DSBGA (12) package. As shown in Table 1-1, the INA2191 has gains that range from 25V/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 plus the bias voltage supplied to the corresponding reference pin. The device can accurately sense voltage drops across shunts at -0.1-V to +40-V common-mode voltages, independent of supply voltage. The device survives common-mode voltages from –0.3 V to +42 V. The device operates with supply voltages between 1.7 V and 5.5 V, and draws a typical of 48 µA per channel at room temperature.
