2 Overview
The INA241x device is a voltage-output, high-side current sense amplifier in a small SOT-23 (8) package with
enhanced common-mode PWM rejection and bandwidth of 1 Mhz for all gain options. As shown in
, the INA241x has gains that range from 10 V/V to 200 V/V, depending on the gain option that is
selected. The device is in preview mode and only the following options of INA241A1, INA241A2 and INA241A3
are populated on this EVM at this time. 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 –4-V to +110-V common-mode 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 2.5 mA at room temperature.
