2.3.6 INA901-SP

The INA901-SP is a voltage-output, current-sense amplifier that can sense drops across shunt resistors at common-mode voltages from –15V to 65V, independent of the supply voltage. The INA901-SP operates from a single 2.7V to 16V supply, drawing 700μA (typical) of supply current.

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