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 INA4290 device is a voltage-output, high-side quad-channel current sense amplifier in a QFN (16) package.
As shown in
, the INA4290 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 320 µA per channel at room temperature.
