3 Description
The INA296x-Q1 is an ultra-precise, bidirectional
current sense amplifier that can measure voltage
drops across shunt resistors over a wide commonmode
range from –5V to 110V, independent of
the supply voltage. The high-precision current
measurement is achieved through a combination of
low offset voltage (±10μV, maximum), small gain error
(±0.01, maximum) and a high DC CMRR (typical
166dB). The INA296x-Q1 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 1.1MHz and fast settling time.
The INA296x-Q1 operates from a single 2.7V to
20V supply, drawing 2.5mA of supply current. The
INA296x-Q1 is available in five gain options: 10V/V,
20V/V, 50V/V, 100V/V, and 200V/V. Multiple gain
options allow for optimization between available
shunt resistor values and wide output dynamic range
requirements.
The INA296x-Q1 is specified over operating
temperature range of −40°C to 125°C.
