INA290EVM
2 Overview
The INA290-Q1 device is a voltage-output, high-side current sense amplifier with an enable pin in a very-
small SC-70 (5) package. As shown in
Table 1 , the INA290 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 +110-V common-mode voltages, dependent of
supply voltages.The device survives common-mode voltages from –20 V to +120 V. The device operates
with supply voltages between 2.7 V and 20 V, and draws a typical of 350 µA at room temperature.
