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 with 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.
