Linear comparators are electronic circuits used to compare two input voltages, and they are quite versatile. The TS393CDT is an example of a linear comparator, whose main application is to compare a reference potential to another voltage level, producing an output signal when the levels are different. This output signal can be used as an indication of a level crossing, or for control purposes. Further, the TS393CDT can be used for various tasks such as frequency detection, threshold monitoring, and power supply control.

At its core, the TS393CDT is built around a differential amplifier, or a differential pair made from two transistors. The differential pair amplifies the difference between its two input terminals, producing an output proportional to the difference between the two inputs. The TS393CDT is designed to interface and respond to input signals in the range 0 to 200mV. To reduce the possibility of any error due to offset drift, the input amplifier stage is compensated with trimable resistors, which help to keep the differential amplifier balanced.

In addition, adjustable hysteresis is implemented by means of the feedback resistor circuit. The hysteresis adjusts the comparator’s response window. This is important since if the comparator cannot distinguish between two subsequently high and low input pulses, then it may not be able to synchronize to the signal and will not provide the required output. The hysteresis general allows for a wider range of input signals, allowing for more accurate and synchronized outputs. Alternatively, a capacitor may be used instead of resistors to control the hysteresis but this can require additional computations.

The comparator output is a square-wave whose pulse width depends on both the input signal and hysteresis. The voltage levels of the comparator’s output are dependent on the ‘low’ and ‘high’ levels at its input terminals. The ‘low’ and ‘high’ levels of the input can have either a positive or negative voltage. The comparator’s output will be ‘high’ or ‘low’ depending on the input levels; this means that the level of the comparator’s output will shift when the input levels are shifted.

In addition to this, comparators such as the TS393CDT also come with adaptive skew control capability, which allows the compensation to be synchronized. This is especially useful in situations where the input can change frequency or amplitude due to various factors. The adaptive skew control enables synchronization of the comparator’s output relative to its input, allowing for better overall accuracy and stability.

Overall, linear comparators such as the TS393CDT have a number of advantages over other comparators. They are able to accurately compare two input voltages and produce a response signal, complete with adjustable hysteresis and adaptive skew control capability. They are also very versatile, able to be used for a wide range of applications, including frequency detection, threshold monitoring, and power supply control.
