LM211DR Typical application Circuitry

LM211DR

The LM211DR is a differential comparator from Texas Instruments, designed with the capability of operating over a wide range of voltages, from single 5 V supply up to ±15 V dual supplies. An 8-pin small-outline integrated circuit (SOIC) package is the format in which it is offered. This component is optimized for low power consumption while still providing high-speed output switching.

1. Pin 1 (IN-): This is the inverting input pin to which you would connect the voltage that is to be compared. If your application demands comparing a signal to a set reference, this pin will receive the signal.

2. Pin 2 (IN+): The non-inverting input of the LM211DR is where the reference voltage would be applied. The output will change states if the voltage on this pin is higher than the voltage on the inverting input.

3. Pin 3 (Out): The output of the LM211DR is open-collector, requiring an external pull-up resistor to the positive supply voltage for proper logic level output. The input current and intended output speed can be used to modify the resistor's value.

4. Pin 4 (GND): This pin should be connected to the system ground. This ground acts as the reference point for both the input voltages and the power supply.

5. Pin 5 and Pin 6: These pins are used for balancing and strobing but are not always implemented in all versions of the LM211 series. If unused in the LM211DR variant, these pins are typically left unconnected or connected to a potential that disables the strobe feature, often the positive supply voltage.

6. Pin 7 (Vcc+): Attach this pin to the power supply's positive side. The LM211DR functions over a wide range of positive supply voltages, which should be chosen based on the requirements of your particular circuit.

7. Pin 8 (Vcc-): For a single supply operation, this pin would connect to the ground. In a split supply operation, it would connect to the negative supply voltage. The range of operation for the LM211DR makes it versatile for various configurations.

To ensure the accurate operation of the LM211DR, it is recommended to place a bypass capacitor (typically 0.1 μF) between the supply pins (Vcc+ and Vcc-) and ground, as close to the device as possible. This bypass capacitor helps in filtering out noise and stabilizing the supply voltage.

When designing a circuit with the LM211DR, one must be mindful of creating a layout that minimizes the length of the connections to reduce parasitic capacitance and inductance effects, which could otherwise affect the performance of the comparator. Moreover, verifying the LM211DR's datasheet for the specific electrical characteristics pertinent to the device is essential to avoid exceeding its maximum ratings and to ensure that all conditions for proper functionality are met.
