MAX975ESA

The MAX975ESA is a single-channel, general-purpose comparator designed for +3V and +5V single-supply applications. It features three operating modes: high speed, high speed with auto-standby, and low power. In high-speed mode, it boasts a propagation delay of 28ns. The device consumes only 250µA in high-speed mode and reduces to 3µA in low-power mode. An auto-standby feature allows it to automatically switch between low-power and high-speed modes based on input signals.

This comparator is optimized for battery-powered systems, RF ID tags, and keyless entry applications. Its inputs have a common-mode voltage range of -0.2V to (VCC - 1.2V), and the differential input voltage range extends rail-to-rail. The outputs are capable of rail-to-rail operation without external pull-up circuitry, making them ideal for interfacing with CMOS/TTL logic. All inputs and outputs can tolerate a continuous short-circuit fault condition to either rail. The comparator's internal hysteresis in high-speed mode ensures clean output switching even with slow-moving input signals.

The MAX975ESA is available in an 8-pin SO package, suitable for surface mounting. It operates within a temperature range of -40°C to 85°C.
