The MAX9120EXK-T is a linear-comparators device specifically designed for flow, temperature, force, and vibration monitoring applications. It is an integrated voltage-comparator IC with TTL, CMOS, and open-drain logic outputs. With its low power consumption and wide input voltage range from 2.5V to 6.0V, the MAX9120EXK-T is widely used in numerous industrial, consumer, and medical applications.

The MAX9120EXK-T includes on-chip hysteresis logic and voltage reference generator. The outstanding hysteresis of this device sets it apart from its competitors. The internal hysteresis leaves the device in a fixed state until a threshold voltage is exceeded. This feature prevents the output from oscillating due to slow-to-change (noisy) input signals. By programming the external capacitor, the amount of hysteresis can be adjusted by the user.

In addition to its on-chip hysteresis, the MAX9120EXK-T also includes an internal temperature-compensated voltage reference generator. This reference generator is connected to the comparator inputs, allowing the reference voltage to vary with the temperature of the environment. This compensates for changing input conditions due to temperature changes so that the reference voltages remain accurate and consistent.

The MAX9120EXK-T features CMOS and TTL output types. The CMOS outputs allow for fast response to changes in the input voltage. The TTL output allows for higher noise immunity since the output is clamped to the logic level whenever input voltages are outside of the normal range. The open-drain option provides easy integration with external logic circuitry.

Apart from its voltage-comparator function, the MAX9120EXK-T also has a noise filter. This noise filter eliminates unwanted noise by reducing the high-frequency component of an input signal to an acceptable level. This feature helps prevent erratic output changes that can occur due to electrical interference.

In summary, the MAX9120EXK-T is a versatile linear-comparator device that has been designed for flow, temperature, force, and vibration monitoring applications. It features easy integration with external logic circuitry, low power consumption, and an on-chip hysteresis and temperature-compensated voltage reference generator. The TTL, CMOS, and open-drain logic outputs also make this device great for a wide range of applications.
