Linear - Comparators

Comparators are often used in analog to digital systems, because they are able to compare an analog signal to a reference voltage or current. The LT6703CDC-2#TRMPBF is a fully differential high-speed comparator, providing exceptional immunity to digital switching noise and improved dynamic performance. This comparator is necessary for applications that require digital velocity feedback, such as motor control.

• Low input offset voltage
• High frequency operation

Applications

The LT6703CDC-2#TRMPBF is designed for a wide variety of linear and digital applications. It can be used in motor control systems, as well as closed loop speed control feedback systems. It is also used in operational amplifier designs, Multi-Bit DACs, high frequency communication systems, and other linear functions. The comparator is typically used as a comparator with either a single reference voltage or dual reference voltages, depending on the application requirements.

Working Principle

The LT6703CDC-2#TRMPBF is a differential high-speed comparator. The device has two inputs, a reference voltage input and an input signal voltage input. The output of the comparator is a digital signal which is either a logic ‘high’ or ‘low’, depending on the two voltages being compared. When the reference voltage is greater than the input signal voltage, the output of the comparator is a logic ‘high’. When the reference voltage is less than the input signal voltage, the output of the comparator is a logic ‘low’.

The comparator works by comparing the voltage of the reference voltage pin to the voltage of the input signal. Since the reference voltage is a known quantity, the comparator can accurately determine whether the input signal is greater than, less than, or equal to the reference voltage. When the reference voltage is greater than the input signal, the output of the comparator will be a logic ‘high’. When the reference voltage is less than the input signal, the output of the comparator will be a logic ‘low’. The LT6703CDC-2#TRMPBF has high-speed operation, with a response time of 1µs or less, making it a good choice for applications that require fast responses.

The LT6703CDC-2#TRMPBF is able to achieve such high-speed performance by using a differential input stage with high speed clocked comparators driving the output stage. This allows the device to achieve a response time faster than a comparable single-ended design. Additionally, the device is designed to reject high frequency digital switching noise, allowing it to be used in harsh environments without suffering from performance degradation.

Conclusion

The LT6703CDC-2#TRMPBF is a fully differential high-speed comparator, providing exceptional immunity to digital switching noise and improved dynamic performance. It is suitable for applications that require digital velocity feedback, such as motor control, operating amplifier designs, Multi-Bit DACs, high frequency communication systems, and other linear functions. The device provides a fast response time, low power consumption, and excellent noise immunity thanks to its differential input stage.
