3. Personal Safety
a. Wear personal protective equipment (for example, latex gloves or safety glasses with side shields) or
protect the EVM in an adequate lucent plastic box with interlocks to protect from accidental touch.
Limitation for safe use:
EVMs are not to be used as all or part of a production unit.
2 Overview
The INA2290 device is a voltage-output, high-side dual channel current sense amplifier in a VSSOP (8)
package. As shown in
, 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.
