An operational amplifier (Op-Amp) is an electronic device that works with external components like resistors and capacitors to amplify voltage. Therefore, MCP6004 works best for general-purpose tasks and maintains a typical 45 degrees phase margin with a 500pF capacitive load. If you need guidance on using the MCP6004 datasheet Op-Amp, read on to understand the Op-Amp better.

Here are the features of the MCP6004
- Firstly, it is a gain bandwidth product (GBWP) with a gain of 1 MHZ; hence is a low power operational amplifier.
- Secondly, it has a supply/ operating voltage range from 1.8V to 6V
- Also, has an open-loop gain of 112dB
- Fourthly, the Op-Amp has a quiescent current of 100uA and an output pin current of 30mA.
- Then, it has an open-loop gain of 112dB
- The MCP6004 utilizes rail to rail input and output
- Lastly, the Op-Amp has an extended temperature range and is good for most circuit operations.
MCP6004 Application Circuits
Instrumentation Amplifier with Unity-Gain Buffer Inputs
The rail-to-rail input and output properties of the MCP6004 operational amplifier make it perfect for unity gain buffer applications.

Active Second-Order Low-Pass Filter
The MCP6004 has a low input bias current, enabling it to partner the Op-Amp with small capacitors and large resistors.
However, with the application of Op-Amp as a low-pass filter the noise increases with an increase in circuit resistance.

Additionally, using large resistors and parasitic capacitances changes the frequency response. You’ll also need to set the Op-Amp’s bandwidth to be 100 times or more than the filter cutoff frequency.
Therefore, you’re guaranteed a good amplification in such a setup, and the system becomes more sensitive to circuit components tolerances.
