LM358ADGKR Typical application Circuitry

LM358ADGKR

LM358ADGKR is a dual operational amplifier (op-amp) designed for general-purpose applications. It is characterized by its low power consumption, wide supply voltage range, and the capability to operate from a single power supply, making it versatile for a broad spectrum of applications such as sensor interfacing, signal conditioning, and active filtering.

Application Scenarios

A common application for the LM358ADGKR is in active low-pass filters, which are used in audio processing, data signal smoothing, and noise reduction circuits to attenuate high-frequency signals while allowing low-frequency signals to pass.

Parameter Features

- Dual Op-Amps: The LM358ADGKR contains two independent operational amplifiers, enabling the design of two separate circuits or more complex configurations like differential amplifiers.

- Wide Supply Voltage Range: It can operate from a single supply voltage ranging from 3V to 32V, or a dual supply voltage of ±1.5V to ±16V, providing flexibility in various application environments.

- Low Power Consumption: Because of its effective power utilization, this makes it perfect for battery-operated gadgets.

- Input Common-Mode Voltage Range: Includes ground, making the device suitable for single-supply operations.

Circuit Connection Example: Active Low-Pass Filter

Implementing an active low-pass filter with the LM358ADGKR involves several crucial steps:

- Power Supply Connections: Connect the positive supply voltage to the VCC pin (pin 8) and the ground to the VEE pin (pin 4). Ensure the supply voltage is within the 3V to 32V range for single-supply operations.

- Input Signal: Apply the signal to the first op-amp's non-inverting input (pin 3). To set the required input impedance, use a series resistor (R1).

- Feedback Loop: Attach a feedback resistor (R2) between pin 1 of the first op-amp's output and pin 2 of its inverting input. Parallel to R2, connect a capacitor (C1) to ground to set the filter's cutoff frequency.

- Output: The first op-amp's output (pin 1) contains the filtered output. This output will contain frequencies below the cutoff frequency set by R2 and C1.

Design Considerations

When designing with the LM358ADGKR, it's essential to consider the bandwidth and slew rate of the op-amp to ensure it meets the requirements of the application, especially in filters where these parameters are critical for performance. The performance of the op-amp can be directly impacted by changes in the power supply, thus it should be steady and noise-free. Additionally, the layout should minimize the length of signal paths to reduce noise pickup and potential oscillations. Care should also be taken to ensure that the input signals remain within the common-mode voltage range of the op-amp.

In summary, the LM358ADGKR is an excellent choice for designing active low-pass filters in audio processing and signal conditioning applications. By carefully addressing power supply stability, bandwidth and slew rate requirements, input signal levels, and PCB layout considerations, designers can effectively leverage the LM358ADGKR to achieve high-performance filtering solutions.
