Linear - Comparators

The TSM922CUA+ is a quad general-purpose linear comparator commonly used when applications require a low input current, low voltage differences, and low power consumption. It features a symmetric output rail to rail, adjustable input threshold, and a fast response time. It also includes an enabling pin which can be used to put the entire device in a low power state.

Application Field

The many features of the TSM922CUA+ make it an ideal choice for a variety of application fields. This device can be used to measure analog signals, detect threshold levels in audio circuits, and compare inputs to determine the highest or lowest value. It can also be used in data acquisition systems, medical equipment, automotive, and in other applications requiring low current and low voltage differences with fast response time.

Working Principle

The TSM922CUA+ is designed with two differential inputs. These inputs are connected to an internal amplifier whose output is fed to a latch. When an input voltage exceeds its reference voltage, the amplifier output switches and the latch will be set or reset accordingly. The outputs will remain in the respective states until the next comparison cycle. The internal latch of the device can be disabled using the enable pin. The TSM922CUA+ also includes an open-drain power saving mode which allows the device to enter an ultra-low power state.

Conclusion

The TSM922CUA+ is an ideal linear comparator for applications that require low current, low voltage differences, and fast response times. Its symmetric output section and adjustable input threshold make it suitable for a wide variety of applications such as medical, automotive, and data acquisition. Its internal amplifier, latch, and enable pin make it a versatile device with many applications.
