Application Field

The NCS2202SN2T1G application field includes a wide variety of power-sensitive applications, such as portable instrumentation, automotive testing equipment and industrial test points. Its versatility makes it suitable for a broad range of applications. Its linear configuration is well-suited for low voltage devices with a requirement for tight control of supply current, making it an ideal solution in tunable RF power amplifiers, power-sensitive sensing and closed loop control applications. It is useful for Amplifiers where High Input Range Accuracy and Stability is required. The high speed configuration opens up possibilities for ultra-fast system designs.

Working Principle

The NCS2202SN2T1G Linear-Comparator has two common-mode inputs, a positive and negative input. The inputs can be held at any voltage when the power supply is applied. Output is the difference in voltage between the two inputs. Output of the comparator depends on the relative level of the two inputs. When the negative input is greater than the positive one, the output is low. On the other hand, when the positive input is higher than the negative one, the output is high. When the two inputs are equal, the output depends on the output state which was set before the inputs become equal.

The NCS2202SN2T1G has an active ground connection pin that enables the user to connect either the positive input or the output ground to other grounds. Flyback protection is used to prevent output latch-up, and the comparator has an internal clamp-diode structure to prevent damage from high input voltages. The NCS2202SN2T1G has been designed to use the lowest possible power when in test mode. This reduces the number of test cycles required, and ensures that the tests are completed faster.

Conclusion

NCS2202SN2T1G are high-speed, low-power CMOS linear- Comparators designed for a wide range of applications with tight control of power dissipation. The two common-mode inputs allow for level shifting, voltage translating, and voltage follower operation. Its flyback protection and clamp-diode structure prevent damage from high input voltages, making the NCS2202SN2T1G an ideal choice for amplifiers, RF power amplifiers and closed loop control applications. It is also suitable for test points and portable instruments due to its low power consumption when in test mode.
