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