LM211DRE4 Typical application Circuitry

LM211DRE4

The LM211DRE4 is a variant within the LM211 family of high-speed differential voltage comparators, renowned for their reliable performance in systems that require voltage monitoring or quick response times. This particular component is designed to function effectively across a vast array of applications, from simple voltage level detection to more complex systems like analog-to-digital converters.

1. Supply Voltage Pins:

- Pin 8 (VCC+): This pin on the LM211DRE4 is where you'll supply the positive voltage. Adaptable to a broad spectrum of voltages, the device can handle between 3V and 36V when operating with a single power source, or between ±1.5V and ±15V when utilizing a dual supply approach.

- Pin 1 (GND/VCC-): When the LM211DRE4 is configured with a single supply, this pin will be your ground connection. Alternatively, in a dual supply setup, this pin will be tied to the negative voltage supply.

2. Input Pins for Voltage Comparison:

- Pin 2 (Inverting Input): The LM211DRE4 compares any voltage present at this pin with the voltage at the non-inverting input. Typically, a reference voltage would be applied here.

- Pin 3 (Non-Inverting Input): This is where the input voltage, which you want to compare to the reference voltage on the inverting input, is connected.

3. Output Pin Configuration:

- Pin 7 (Output): For the LM211DRE4 to signal its comparison result, this open-collector output requires an external pull-up resistor. The output is dragged to ground when there is a voltage differential between the non-inverting and inverting inputs.

4. Stabilization and Feedback: To prevent the LM211DRE4 output from toggling erratically due to noise, a feedback resistor is often added between Pin 7 (Output) and Pin 3 (Non-Inverting Input) to introduce hysteresis. For temporal response tuning, a capacitor can be connected in parallel with this resistor, dampening the output's reaction to transient changes.

5. Biasing and Protecting the Inputs: Appropriate biasing is necessary for the inputs. Select resistors that match the input bias current requirements as specified in the LM211DRE4's datasheet. To protect against voltage spikes, diodes may be placed across the inputs.

6. Balance and Strobe Pins:

- Pin 4 (Balance/Strobe): While essential in some advanced applications for offset balancing or enabling the strobe feature, this pin may not be used in standard comparator configurations.

- Pin 5 (Balance): Works in conjunction with Pin 4 for the purpose of differential input voltage balancing but is typically left unconnected in basic applications.

7. Non-connected Pin:

- Pin 6 (NC/No Connection): This pin is not utilized and thus does not need to be connected within the circuit.

In any design involving the LM211DRE4, a bypass capacitor is generally placed near the power supply pins to filter supply line disturbances, ensuring the device's stability. While integrating the LM211DRE4 into a design, proper grounding and adherence to the datasheet's layout recommendations are essential to maximize the device's performance and reliability.
