Linear - Comparators

The CD8447DR2G is a Linear - Comparators device most commonly used for efficient resistor ladder-based voltage designs. The CD8447DR2G can be used for many different applications, but its most popular use is for micropower linear comparators in a low-power system.

The CD8447DR2G operates off a supply voltage of 2 volts and has low power consumption for a Linear - Comparator. The device features a high accuracy, low power comparator with a wide operating range. The device uses an adjustable input “tail current” feature to adjust the sensitivity of the output signal. This allows the user to adjust the response characteristics of the device. The device also features a hysteresis parameter that can be used to improve the signal noise rejection ratio.

The CD8447DR2G’s output is a digital signal that is used to indicate a comparison. The output will be either high (1) or low (0) depending on the voltage applied to the input. The input voltage is compared to the reference voltage, and the output will indicate whether the input voltage is higher or lower than the reference voltage. The hysteresis parameter can be used to provide extra noise rejection of the input signal.

The CD8447DR2G can be used in many application areas, such as battery management systems, audio power management circuits, microwave circuits, automotive systems and communications systems. It is also used for voltage sensing, power management, and voltage regulation. Due to its low power consumption, the device is suitable for low power application.

The CD8447DR2G works with a differential input signal, applying opposite polarity voltages to a high (HI) and low (LO) input, which are compared to two separate internal reference voltages. When the signal on the HI input is greater than the reference voltage on the HI input, then a digital high output is produced. When the signal on the LOW input is less than the reference voltage on the LOW input, then a digital low output is produced.

The control of the device is further enhanced by the use of an optional input lag circuitry which provides hysteresis and improved noise immunity. This optional input lag also allows the user to control the sensitivity of the output signal as well as the level of hysteresis.

The CD8447DR2G is an efficient, low power device and is suitable for many linear applications. The device features a high accuracy, low power comparator with a wide operating range. The adjustable input “tail current” feature allows for adjustable sensitivity and the hysteresis parameter enables improved signal noise rejection. The device can be used in many applications such as battery management systems, audio power management circuits, microwave circuits, automotive systems and communications systems.
