INA296B 的說明
The INA296x is an ultra-precise, bidirectional current sense amplifier than can measure voltage drops across shunt resistors over a wide common-mode 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 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 operates from a single 2.7 V to 20 V supply, drawing 2.5 mA of supply current. The INA296x 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 is specified over operating temperature range of −40°C to +125°C.
