The CD4585BPWRG4 belongs to the family of logic-comparators. A comparator compares two analog values and generates a digital signal of high or low state, depending on the result of comparison. This product can handle dual voltage ranges, from 4.5V to 16V and from 2.7V to 6.5V. It offers a wide range of compatibility with TTL and CMOS. It is suitable for interfacing between analog and digital circuits, as well as for design of data conversion systems.

Application Field of CD4585BPWRG4

CD4585BPWRG4 can be used in a wide range of applications. It can replace a variety of products to reduce the cost of design and save board space. For example, this device can be used in the primary side of switching regulators, AC/DC converters, and DC/DC converters to compare the output voltage and current with a reference voltage and current. It can also be used in secondary side applications, such as motion controlled systems, to compare the voltages from different sensors and the time delay of motor responses to the ideal values.

Working Principle of CD4585BPWRG4

The working principle of CD4585BPWRG4 is based on the difference in voltage between two input terminals. The comparator compares the voltage at the two input terminals and determines which one is larger. When the voltage at the non−inverting (V+) input exceeds that at the inverting (V−) input the output state becomes high, and the opposite is true when V− is higher than V+. This is the basic principle of comparison.

In order to precisely compare two input signals, the transition ratio must be very high. The transition ratio of CD4585BPWRG4 is typically 2000:1 or higher. This means that for a small variation in the input voltages, the output state does not change. The comparator also includes an open collector output facility, allowing real-time monitoring and control of the output state. The output can be used both as a control signal or an indicator signal.

CD4585BPWRG4 is a high-performance device that has been carefully designed to provide excellent accuracy and stability in comparison operations. Careful design and precision manufacturing techniques ensure that the product meets the required specifications and offers improved performance over a wide range of operating conditions. This device is designed to provide reliable operation throughout its life, even in harsh environment, such as extreme temperatures, humidity, and changing light conditions.
