LMH6643MMX/S7002247 Typical application Circuitry

The LMH6643MMX/S7002247 is a high-speed, low-power, voltage feedback operational amplifier (op-amp). It is known for its excellent speed-to-power ratio, making it suitable for a wide range of applications.

Applications: This chip is commonly used in applications requiring high-speed signal processing, such as video amplifiers, ADC/DAC buffers, active filters, and high-speed data acquisition systems.

Key Parameters:

1. Supply Voltage Range: 2.7V to 12V, accommodating various power supply configurations.

2. Output Current: Capable of delivering up to 80mA, suitable for driving a range of loads.

3. Slew Rate: 130V/µs, ensuring fast response times in high-speed applications.

4. Bandwidth: 75MHz, providing ample frequency response for a wide range of signals.

5. Input Offset Voltage: Typically 3.5mV, ensuring accuracy in signal processing.

Designing a Non-Inverting Amplifier with the LMH6643MMX/S7002247

1. Connection to Power Supply:

- Single-Supply Setup: Attach the positive supply to pin 8 (V+) and ground to pin 4 (V-) of the LMH6643MMX/S7002247 to create a 5V supply.

2. Input Signal Coupling:

- AC Coupling: Use a capacitor (e.g., 1µF) to couple the input signal to the non-inverting input (pin 3) of the LMH6643MMX/S7002247, blocking any DC component of the signal.

3. Feedback Network:

- Gain Setting: Connect a feedback resistor (Rf) from the output (pin 1) to the inverting input (pin 2), and a resistor (Rg) from the inverting input to ground. For a gain of 2, use Rf = Rg = 10kΩ.

4. Output Load:

- Load Considerations: Ensure that the load connected to the output (pin 1) of the LMH6643MMX/S7002247 does not exceed the maximum output current rating of 80mA. Use a series resistor if necessary to limit the current.

5. Decoupling Capacitors:

- Power Supply Decoupling: Place a 0.1µF ceramic capacitor close to the V+ pin of the LMH6643MMX/S7002247 to provide local power supply decoupling and improve noise performance.

Crucial Design Pointers

- Supply Voltage Range: Verify that the supply voltage falls within the LMH6643MMX/S7002247's designated range.- Signal Bandwidth: Design the circuit to accommodate the bandwidth of the input signal, considering the 75MHz bandwidth of the LMH6643MMX/S7002247.

- Slew Rate: Ensure that the slew rate of the LMH6643MMX/S7002247 is sufficient for the application's speed requirements.

- Load Compatibility: Make sure the load attached to the output doesn't draw more current than the chip can handle.

Because of its high speed performance and low power consumption, the LMH6643MMX/S7002247 chip can be used for a variety of tasks, including non-inverting amplification. Utilizing the capabilities of the LMH6643MMX/S7002247, you may design a dependable and effective circuit by adhering to the comprehensive circuit design rules and taking important variables into account.
