The INA310x is a high or low-side high-speed current-sense amplifier that offers a wide common-mode range, precision zero-drift topology, excellent common-mode rejection ratio (CMRR) and fast slew rate. Different gain versions are available to optimize the output dynamic range based on the application. The INA310x is designed using an architecture that enables low input bias current of 20 µA with a specified common-mode voltage range from −4 V to 110 V with signal bandwidths up to 1.3 MHz. The INA310x incorporates an open-drain comparator and internal reference providing a 0.6-V threshold. An external resistor 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 (see the RESET Function section).
