MCP6004 Datasheet – A Look Into the Low Power Quad Op-Amp 

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.

MCP6004 Features

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.

Additionally, the wide bandwidth and low quiescent current make it more suitable for buffering in instrumentation amplifier circuits.

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.

Peak Detector with Clear and Sample CMOS Analog Switches

The MCP6004 has a low input bias current, a high input impedance, and rail-to-rail input/output. Therefore, it makes it good for peak detector applications.
