LT6703IDC-2

Linear-Comparators

The LT6703IDC-2 is a linear comparator that can be used for various applications. This comparator is available as a single-channel, single-ended component, as well as an optional dual-channel, differential component. It is designed to operate from a single supply of +3 to +26 volts and is capable of driving a 3V output with a minimum of 0.8V in a rail-to-rail output configuration. It is also specified for a quiescent current of only 1.2mA, so it can be used in battery operated applications with low power consumption.

Application Field:

The LT6703IDC-2 comparator can be used in many types of applications, such as pulse width modulation (PWM) applications, with its high speed and low power consuming features. It can be used in low power applications, such as portable medical devices where high accuracy and low power operations are required. It can also be used in automotive applications, providing reliable operations under extreme temperatures. Furthermore, it can be used in voltage sensing circuit applications, switch mode power supplies, low level control, current monitoring, and many more.

Working Principle:

The LT6703IDC-2 works by comparing the magnitude of two input signals, one at its non-inverting input and the other at its inverting input. When the non-inverting input voltage is greater than the inverting input voltage, the output of the comparator turns on and saturates, providing a digital output logic state. Conversely, when the non-inverting input voltage is less than the inverting input voltage, the output of the comparator turns off, providing a digital output logic state. The output of the comparator is electric-current driven, meaning the output voltage is dependent on the amount of electric-current sinked or sourced by the comparator. By using an appropriate load, the electric-current sinking output at the positive supply can be transformed into a logic high, while the electric-current sourcing output at the negative supply can be transformed into a logic low. The LT6703IDC-2 also has an open collector output, meaning that no output voltage exists unless a active output pull-up resistor is connected.
