LM224DR Typical application Circuitry

LM224DR

The LM224DR is part of the LM224 series, which consists of low-power quad operational amplifiers. These devices are designed to operate from a single power supply and can also be adapted to dual supply modes. The LM224DR is notable for its ability to handle wide voltage ranges and its low supply current draw, making it suitable for battery-powered devices, sensor amplifiers, and other applications requiring multiple op-amps in a single package.

1. Power Supply Pins:

- Pin 4 (VCC+): Connect this pin to the positive supply voltage, which can range from 3V to 32V for single-supply configurations or ±1.5V to ±16V for dual-supply operations.

- Pin 11 (GND/VCC-): This pin is for the ground reference in single-supply setups, or the negative supply voltage for dual-supply modes.

2. Operational Amplifier Inputs and Outputs:

- Pins 1, 2, and 3 (Output, Inverting Input, Non-Inverting Input of Op-Amp 1): The LM224DR's first operational amplifier's output is Pin 1, with Pin 2 as the inverting input and Pin 3 as the non-inverting input.

- Pins 5, 6, and 7 (Output, Inverting Input, Non-Inverting Input of Op-Amp 2): The second op-amp follows a similar configuration with Pin 5 for output, Pin 6 for the inverting input, and Pin 7 for the non-inverting input.

- Pins 8, 9, and 10 (Output, Inverting Input, Non-Inverting Input of Op-Amp 3): Respectively, for the third amplifier within the LM224DR.

- Pins 12, 13, and 14 (Output, Inverting Input, Non-Inverting Input of Op-Amp 4): These pins serve the fourth operational amplifier.

3. Feedback and Frequency Compensation:

- Each operational amplifier in the LM224DR typically requires a feedback path, which can be established by connecting the output to the inverting input either directly for unity gain or through a resistor network for different gain settings.

- To ensure stability, especially in bandwidth-limited configurations, a capacitor might be added to the feedback loop or between the inverting input and ground.

4. Biasing and Input Protection:

- The non-inverting inputs of the LM224DR may require a path to ground or a reference voltage via a resistor, depending on the desired operation point.

- Protecting the inputs against voltage spikes can be achieved by placing diodes or resistors in series with the input pins.

5. Decoupling for Noise Reduction: To safeguard the LM224DR against power supply fluctuations and noise, a decoupling capacitor is generally placed between the VCC+ and GND pins in close proximity to the IC.

When incorporating the LM224DR into any circuit, it is imperative to ensure that the connections are secure and follow the recommended practices outlined in the device's datasheet. This ensures optimal performance and prevents any instability or malfunction. Consulting the LM224DR datasheet is also critical for acquiring detailed specifications on the acceptable range of external components, such as feedback resistors or capacitors, that the device will interface with.
