Linear comparators offer superior accuracy, high speed and low-voltage operation with a wide range of applications. The LM139DT is a dual comparator that uses one or two compartments of a differential amplifier to compare two differential inputs. The LM139DT offers high accuracy and performance over wide temperature ranges of -40°C to 85°C, making it suitable for use across a wide variety of automotive and industrial applications. The LM139DT features a low-voltage operating range of 2.7 V to 10V and a maximum quiescent supply current of only 880µA.
The LM139DT consists of two independent, high-speed voltage comparators with an open-collector output. The differential inputs are rejected from the first input stage by a relatively high-value resistor. This creates two isolated comparators that can be used to detect different input signals and provide a logic output. Each comparator has two separate outputs that can be used to reset logic devices or to provide a logic output for further digital processing.
The LM139DT comparator has several advantages that make it ideal for use in automotive and industrial applications, including: low-voltage operation, high-speed operation, low-noise operation, low-current consumption and high-precision operation. The LM139DT is also very easy to use and highly reliable, as it is certified to the Automotive Electronics Council AEC-Q100 standard.
In operation, the LM139DT essentially works by comparing two separate differential inputs, and then emits an output when the two signals are either equal or not equal. When the input levels are the same, the output will be high, forming a flip-flop condition. When the input levels are not equal, the output will be low, thus creating a latch condition. The output signals of the LM139DT can then be used to reset logic devices or provide logic output for further digital processing.
The LM139DT has a wide variety of applications across automotive and industrial applications, including: temperature measurement and control, automotive engine control, motor control, vibration sensing and motor speed detection. The LM139DT is an extremely reliable and cost-effective solution for any application where precise measurements need to be taken over a wide temperature range.
Overall, the LM139DT is an excellent choice for automotive and industrial applications where precise measurements need to be taken over a wide temperature range. It offers low-voltage operation with high accuracy, speed and low-current consumption, making it ideal for use in a wide variety of applications. With its certification to the Automotive Electronics Council AEC-Q100 standard, the LM139DT is an extremely reliable and cost-effective solution for any application where precision and accuracy are critical.
