Linear comparators are commonly used in many applications in industry, communication systems, and analysis systems. A linear comparator, also known as a linear amplifier, is a type of integrated circuit (IC) that measures two electronic signals and compares the level of those signals. The TS861IN is a widely used linear comparator from the well-known manufacturer of integrated circuits, Texas Instruments. In this article, we will look at the applications and the working principle of the TS861IN.

Applications of the TS861IN

The TS861IN is a dual-input linear comparator which can switch from either positive or negative logic inputs. It is an ideal device for use in many applications such as AC power system protection, single supply circuits, power supply sequencing and temperature sensing. The TS861IN can also detect over-temperature conditions in thermal protection and monitoring circuits. Other applications include switch debounce, light intensity control and voltage reference.

Working Principle of the TS861IN

The TS861IN uses a differential amplifier as the core of its input stage. This differential amplifier consists of two inputs, one positive and one negative. The input signals are compared to each other and, when they differ by more than the specified amount, the comparator will switch from one logic to the other. The TS861IN operates from a supply voltage range of 3V to 16V and can handle supply currents up to 16mA. Its output is fully output compatible with common logic levels and can be used in applications that require sensitive, low power operation.

The TS861IN has an input range of 0 Volts to 16 Volts and a gain of up to 10. It has an offset voltage of 0.3 Volts max and short-circuit protection up to 16V. The TS861IN has a very high common-mode rejection ratio of 85dB, which couples a large rejection of external interference to the differential signals. This makes the TS861IN an ideal choice for applications where high accuracy and low power are required.

The TS861IN is available in an 8-pin package, which minimizes the amount of footprint area needed to use the device. In addition, the TS861IN has an integrated output driver and level shift circuit, which simplifies design and reduces the cost of the system. The TS861IN has an operating temperature range of -40°C to 85°C, making it suitable for a wide range of temperatures.

Conclusion

The TS861IN is a widely used linear comparator from Texas Instruments. It is used in many applications such as AC power system protection, single supply circuits, power supply sequencing and temperature sensing. It has an input range of 0 Volts to 16 Volts, an offset voltage of 0.3 Volts max, a gain of up to 10, and a common-mode rejection ratio of 85dB. In addition, it has an integrated output driver and level shift circuit, and operates over a wide temperature range of -40°C to 85°C. The TS861IN is available in an 8-pin package, making it easy to use and cost effective.
