3 Description

The INA950-SEP is an ultra-precise, current-sense amplifier that can measure voltage drops across shunt

resistors over a wide common-mode range from 2.7V to 80V. The ultra-precise current measurement accuracy

is achieved thanks to the combination of an ultra-low offset voltage of ±12µV (maximum), a small gain error

of ±0.1% (maximum), and a high DC CMRR of 160dB (typical). The INA950-SEP is not only designed for DC

current measurement, but also for high-speed applications (such as fast overcurrent protection, for example)

with a high bandwidth of 1.1MHz and an 85dB AC CMRR (at 50kHz).

The INA950-SEP provides the capability to make ultra-precise current measurements by sensing the voltage

drop across a shunt resistor over a wide common- mode range from 2.7V to 80V. The INA950-SEP is available

in the TSSOP-8 package.

The INA950-SEP operates from a single 2.7V to 5.5V supply while only drawing 370µA from the supply (typical).

The low offset of the zero-drift architecture enables current sensing with low ohmic shunts as specified over the

operating temperature range (−55°C to 125°C).
