3 Description

The INA901-SP is a voltage-output, current-sense

amplifier that can sense drops across shunt resistors

at common-mode voltages from –15 V to 65 V,

independent of the supply voltage. The INA901-SP

operates from a single 2.7-V to 16-V supply, drawing

700 μA (typical) of supply current.

The gain of the INA901-SP is 20 V/V. The 130-kHz

bandwidth simplifies use in current-control loops. The

pinouts readily enable filtering.

The device is specified over the extended operating

temperature range of –55 °C to 125 °C and is offered

in an 8-pin CFP package.
