TLV3402CDGK

TLV3402CDGK is a low-power linear comparator manufactured by Texas Instruments. The device is designed to provide precise, reliable, and fast circuits that compare two voltage levels and can be used in a variety of applications.

TLV3402CDGK is a dual-channel 8-pin linear comparator operating on a single +5V or +3V supply. It works with a wide range of input voltages, from -0.3V to +6V. One of the distinguishing features of the TLV3402CDGK is its high speed of 1µs max.

TLV3402CDGK employs a fully differential amplifier architecture for precise and fast performance. It will compare two input voltages with each other, and the output will reflect the relative voltage difference between the two inputs. When the voltage of one input (IN+ terminal) is greater than the other, the output (OUT terminal) signal is active-HIGH. When the voltages of both inputs are equal, the signal will switch to the inactive-LOW state.

The device is also equipped with an open-drain input signal, which is used to enable or disable the comparator independently of its input signal or power supply voltage. This allows the user to turn the comparator off and save power, while still keeping the logic state of the output unchanged.

TLV3402CDGK is ideal for use in battery-powered devices, as it has a low quiescent current of 0.1mA, and a supply current of 4mA. It also provides excellent accuracy and reliability and can operate over the temperature range up to +125oC.

TLV3402CDGK can be used in applications like motor control, temperature and speed control, high-precision current measurement, low-power process control, and signal fault detection. It is also suitable for systems with complex logic circuitry, such as alarm systems and surveillance systems.

In summary, TLV3402CDGK is an easy-to-use, low-power linear comparator that offers excellent performance and reliability. Its wide input range and low supply current makes it ideal for a variety of applications, and its open-drain input signal allows the user to turn the comparator off and save power.
