CMP401GSZ is a type of linear-comparator. It is commonly used in portable consumer electronics such as handheld calculators, digital cameras and watches. The CMP401GSZ operates in two modes: Single-Supply and Dual-Supply. The operating voltage range is 1.95 V to 5.5 V and the maximum current consumption is 8 mA.

In single-supply mode, two signals (A and B) are compared and the output of the device is either high or low depending on the relationship between the two inputs. One input (A) is receiving the power supply voltage, while the other (B) is variable. If A is greater than B, the output is high, otherwise it is low. The hysteresis switchover voltage (when the output switches states) is typically 100 mV for CMP401GSZ.

In dual-supply mode, one input (A) is connected to a positive voltage, while the other (B) is connected to a negative voltage, usually ground. The output is low when A is less than B, and high when A is greater than B. Again, hysteresis switchover voltage is typically 100 mV in this mode.

The device is useful in minimizing the errors resulting from noisy data lines, as it can ignore low-amplitude input so that they cannot cause false data transitions. The output is also a low-impedance CMOS output and can drive up to 120 pF loads. Additionally, the current consumption of the device is low and can be sub 1 uA, making it one of the best choices for battery-operated electronics where power savings are especially important.

The CMP401GSZ can also be used as a voltage reference circuit. It can be used to compare two voltage sources, which can then be used to modify the reference voltage. With the adjustable hysteresis, it can be adjusted to prevent excessive toggle between the two states. This is useful if the reference voltage needs to be adjusted regularly, such as for calibration.

CMP401GSZ linear-comparator is a versatile device suitable for various consumer electronics. It has a wide operating voltage range, low current consumption and adjustable hysteresis. Its output can drive up to 120 pF loads and also used as a voltage reference circuit. All these features make CMP401GSZ a great choice for battery-operated portable consumer electronics.
