The LM211DRE4 is a precision, low-power comparator designed to operate from a +4 to +36 volts supply voltage in industrial, commercial and automotive IoT application areas. It is a single package monolithic amplifier featuring two independent very high precision comparators, enabling analog SPDT logic operations without requiring external components.
The LM211DRE4 has a high input impedance, low input bias current and low offset voltage, making it ideal for many high precision, low amplitude signal applications. With a full temperature range of -55°C to +125°C, the LM211DRE4 is also very suitable for applications in extreme environments.
The LM211DRE4 has an hysteresis of up to 50mV. The hysteresis prevents chattering of the output when the inputs are close to the trigger level. The comparator includes open-collector outputs and Schmitt action making it robust against noise and other transient signals on the inputs.
The LM211DRE4 application fields include industrial, automotive and IoT. It can be used for safety and alarm systems as well as in control, automation, robotics and 3D printing applications. It can also be used to compare analog and digital signals in circuit designs.
The LM211DRE4 works on the principle of comparing two input signals and deciding based on those two inputs. It makes the decision using a comparator circuit, which consists of two voltage sources, two resistors, two transistors and two diodes.
When the input signal to be compared is applied to the non-inverting input and the reference signal is applied to the inverting input, if the input signal is higher than the reference signal, then the comparator output will be high. If the input signal is lower than the reference signal, then the comparator output will be low.
The LM211DRE4 can also provide an open-collector output. This output can be used to control other digital devices. It can also be used as an interrupt for an embedded microcontroller, allowing the microcontroller to react to an input change.
The LM211DRE4 is ideal for analog-to-digital conversion. It can be used to compare an analog signal voltage to a reference voltage, such as a fixed 5V or a voltage stair-like ramp. The result of the comparison can be used to determine whether the analog signal is above or below the reference voltage.
The LM211DRE4 is a precision, low-power comparator that has many applications in a wide range of applications. It features low current consumption, wide temperature range and low propagation delays, making it very suitable for use in automotive, industrial and IoT applications.
