AD8672ARZ Typical application Circuitry

AD8672ARZ

AD8672ARZ is a high-performance, precision operational amplifier that is part of the AD867x series from Analog Devices. This dual op-amp is known for its low noise, low offset voltage, and high speed, making it suitable for applications in active filters, precision instrumentation, data acquisition systems, and medical devices.

The key specifications and features of AD8672ARZ include:

- Dual operational amplifier

- Maximum low offset voltage of 125 μV

- Maximum low input bias current of 1.0 pA

- Low noise: 8 nV/√Hz @ 1 kHz

- High bandwidth: 10 MHz

- Rail-to-rail output

- Single-supply operation: 5 V to 30 V

- No phase reversal

Now, let's explore an application scenario of AD8672ARZ in a precision active low-pass filter circuit.

Step 1: Determine Filter Specifications

- Finding the low-pass filter's characteristics, including the cutoff frequency, gain, and filter order, is the first step.

Step 2: Attach the input signal to the AD8672ARZ's reversing input.

- The input signal needs to be connected to pin 2 of the AD8672ARZ, which is the inverting input.

Step 3: Provide Power to the Chip

- Attach pin 4 (V-) to the negative power supply and pin 8 (V+) to the positive power supply. Ensure that the supply voltage is within the range of 5 V to 30 V.

Step 4: Configure the Feedback Loop and Filter Components

- Connect the output (pin 1) to the inverting input (pin 2) using a feedback resistor. The filter components, including resistors and capacitors, should be connected according to the filter design to form the low-pass filter.

Step 5: Attach the Output to the Following Stage

- The subsequent stage of the circuit's input can then be linked to the output of the AD8672ARZ.

When designing the circuit, these factors should be considered:

1. Stability and Bandwidth

- AD8672ARZ has a high bandwidth of 10 MHz, which is suitable for precision filtering applications. However, it is necessary to ensure the circuit's stability and minimize external interference.

2. Power Supply Noise and Ripple

- The power supply for AD8672ARZ should be clean and free from noise and ripple to ensure the op-amp performs optimally.

By following these steps and considerations, AD8672ARZ can be effectively used in a precision active low-pass filter circuit, ensuring that the desired frequencies are passed while unwanted high-frequency signals are attenuated.
