The INA299 is a
precise, bidirectional current sense amplifier that can measure voltage drops across shunt
resistors over a wide common-mode range from –2V to 80V, independent of the supply
voltage. The high-precision current measurement is achieved through a combination of low
offset voltage (±150µV, maximum), small gain error (±0.25%, maximum) and a high DC
CMRR (typical 120dB). The INA299 is not only designed for high voltage, bidirectional DC
current measurements, but also for high-speed applications (such as transient detection and
fast overcurrent protection) with a high signal bandwidth of 650kHz and fast settling
time.
The INA299 operates
from a single 2.7V to 12V supply, drawing 650µA of supply current. The INA299 is available in three gain options: 20V/V, 50V/V, 100V/V.
Multiple gain options allow for optimization between available shunt resistor values and
wide output dynamic range requirements.
The INA299 is
specified over operating temperature range of −40°C to +125°C and is offered in a 6-pin
SOT-23 package.
