VSSOP (DGK)-8-14.7 mm² 3 x 4.9
The INA310x-Q1 is an ultra-precise current sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range from –4 V to 110 V, independent of supply voltage with an integrated comparator. The high precision current measurement accuracy is achieved through a combination of low offset voltage (20 µV, maximum), small gain error (0.15%, maximum) and a high DC CMRR (160 dB, typical). The INA310x-Q1 has a high signal bandwidth of 1.3 MHz designed for high voltage DC current measurements and high-speed applications like fast overcurrent protection.
The INA310x-Q1 incorporates an open-drain comparator and internal reference that provides a 0.6 V threshold. An external resistive divider sets the current trip point. The comparator includes a latching capability that can be made transparent by grounding (or leaving open) the RESET pin.
The INA310x-Q1 operates from a single 2.7 V to 20 V supply and draws 1.6 mA of supply current. The INA310x-Q1 is available in five gain options: 20 V/V, 50 V/V, 100 V/V, 200 V/V, and 500 V/V. These gain options address a wide dynamic range of current-sensing applications.
